Dear Andrew Robinson: I Know Whats Inside Your Speakers.

Danny, I love your hospitality and It makes you one of my favorite people on the internet.

Thank you Danny, I learned so much about crossover design from your videos, I was able to modify the kit I purchased, I am so impressed by simply changing the caps and resistors, about 65 bucks and found out the supplied components were worth less than 12 dollars. The best speaker I have ever owned!

This is the most humble and informative "get off my lawn" I have ever seen.

What you do is a very valuable service. I review, build and teardown in-ear monitors and i've seen a LOT of bad engineering and thought to myself, "man i'd hate to waste this potential"
the crossover is the most important piece of a multi-speaker enclosures. It is the literal beating heart of the speaker.

What GR Research does is greatly appreciated, most speakers are overpriced. Also what GR does is no different than adding a custom exhaust to your car or better brakes or intercooler to improve it’s performance.

Paul from PS Audio also recommends upgrading capacitors with better ones of the same value when the time comes. Last, people modify their cars and etc, there's no difference. The consumer has the ultimate say.

Man, your honesty and openness is what it's all about. Just listen and tell us what you hear. Amen. That attitude separates you from the crowd in my opinion. Keep that ethos and you can't go wrong.

You are super respectful!!! Love what you do and agree 100%!!

Appreciate your support. You’re right, Danny. You provide great value that is not recognized by all. I learn from you all the time and will continue to support. Cheers

Lots of people are interested in what goes into products that they buy or would like to buy. "This Old House" is a prime example of people wanting know what goes into making things operate or work the best. This increases their comfort level when making decisions on what to purchase, what effects it's performance, what elements influence it's characteristics. Some others really don't care and purchase based on advertisements (sheep), what is considered better than their neighbours (sad), what their buddy recommends (lazy?), or what they feel like at that particular time (more money than ambition or brains?). I know who I like sharing my time and energy with. Carry on GR Research.

Truly excellent example of an informal and non-confrontational re-buff!! Great info and great video!!!

You are a professional!
There are many customers who are not interested in learning, or understanding
And there is a public that likes to delve deeper into the product, to understand that they are really getting the best, or trying to make a better product themselves.
Thank you for your service.

We should be concerned about what’s inside. It can reveal what the consumer is actually paying for. It’s not for everyone but for some it does matter.

I watch tons of audio reviews and I have to say this was one of the most informative videos I have seen. Keep up the good works Much appreciated.

I can personally vouch for what the service GR Research provides. I had my PSB 800 crossover tested, and bought new parts to rebuild it; and I was amazed at the difference in sound quality. I could A/B with my old crossover and hear a big difference! I know the service they provide is worth the money.

Thank you for making electronics FUN again.. 😁 I was 12 years of age when I started building simple electronic projects, had a career in engineering, I'm 51 now and I'm still building/repairing/upgrading stuff, mostly high end (tube)amplifiers; improving transformers, caps, resistors, pots, etc.... Not for the money, just for FUN! Glad to see the DIY scene hasn't entirely vanished yet due to lack of time.

Have been listening to stereo components for over 60 years and gr research seems to be one of the most thoughtful commentators I have ever listened to online. I knew someone back in Boulder Colorado in 40 years ago whose whole business is just a little home business was to replace the crossovers with more high quality parts to improve reasonably good stereo speakers. So this guy makes sense... And his presentations are always balanced and thoughtful.

I appreciate what you do, Danny! Got my start in the 1970’s with a Speakerlab kit (remember those?), and I’ve opened and worked on every single speaker I’ve ever purchased. Why oh why does every manufacturer cheap out on something so basic as damping material?! 😂 I don’t have a treated room and I’ve never spent huge amounts of money on speakers, but if you love sound, how can you NOT be curious about what’s inside?! Keep it up, man! 👏

Audio is like the automotive industry. 99% of the folks out there buy a stereo system and they are done. Then there is that 1% that likes tweak what they have. They might use heavy gauge OFC wires. They might replace their op-amps with a higher grade chips. And some might tweak the crossover. Hot rodders have been tweaking cars for years.

BRAVO, DANNY!!! Great info, clearly spoken, wonderfully impartial. Thank you Bro.

This may get some people riled up.
While I think Andrew could have been less condescending with his feelings towards the speaker modding/upgrading community, i very much understand his point.
He doesn't review DIY/modded equipment. His reviews have to be based on what he receives from a manufacturer or retail store. It truly doesn't matter what parts are in the product. If it's good, he explains why. If it's not, he explains why. If it's really bad, he doesn't post a review.
His channel has never been about telling viewers to buy something, take it to someone else to fix problems with it, then take it home and enjoy it.
I guarantee that, as long as he's been in the HIFI world, he understands what crossover parts do to a signal. It's just that, for the purpose of what he and Kristie do with their channel, they don't matter.
If you don't like the way a speaker sounds from the factory, don't buy it. Definitely don't buy expecting Danny to be able to work miracles and make it sound like something that would cost you $3-4K more than what you paid. Just buy one of Danny's kits and get the good stuff the first time.
Much as I don't come to Danny's channel for info on how well a particular pair of Paradigm towers might blend in with the decor of my living room, i don't go to Andrew's channel for detailed technical analysis of how they perform. I watch Andrew and Kristie to get info about it would be to live with a particular product as it comes from the manufacturer.

Danny you've got class thanks for all you have taught me.👍👍👍👍👍👍

Difference is, some people listen with their ears, others listen with their eyes.

When these things devolve into personal criticism they completely lose me.
I get both points of view.
For me, if the quality of the sound is (subjectively to me) is commensurate with the price, then we’re good.
DIY upgrades are a perfectly legitimate way to enjoy the hobby. OTOH, Expecting speakers to sound good with out upgrades is reasonable.
The $/sound ratio is what matters.
As someone whose solder joints look like used bubble gum, I need a decent sound from the factory.
You both have perfectly valid opinions. So let’s get back to the music.

Class act Danny.

A couple of years a ago, I took my Jamo 7.2 speakers in to have my bass woofers repaired. My speakers were 20 years old at the time. The repair shop gave me the option to rebuild my crossovers. There was no need to redesign, just upgrade very old and very cheap components. WOW! What a difference. I spent close to $1000, but the difference was nothing short of amazing. I think Danny is providing a much needed service. It is a shame that speaker manufacturers go cheap on the crossover components, but they do. I am sure some of the improvement was because the components were old, but I know they never sounded this good even when new. By the way, the tweeters and midrange drivers were still in great shape and nothing was done to them.

I've done gr-research upgrades to rp8000f and lrs+ speakers, and they're both phenomenal.

Well put together Danny!! , I have told you before, I truly think you have had a huge part in resurrecting Hifi and get soooo many young people back in the hobby. Cudos and thanks

I follow and enjoy both the AR and GR channels. When I saw the original AR video, I anticipated this response from GR. Personally, I took AR's "don't care" comments in a different context. He's using the "black box" reviewing technique, in that whatever he can't hear or see from the outside is irrelevant. He's "blind testing" things such as the crossover components, dampening material, bracing and binding post material, which aren't visible to him. He can't control the decisions made by the designer and therefore "doesn't care" how the designer got to the end result, only how it fares against the direct competition with its outward characteristics (i.e. sound, aesthetics, construction). Ultimately, he's judging it by the same characteristics as the typical end consumer. I'm sure he appreciates (and can likely hear) the benefits of better crossover components, non-magnetic binding posts, etc. but he also realizes the cost concessions required at certain price points and trade-offs to be made. Perhaps, instead of saying "doesn't care", a more accurate statement would be "I don't want to know". He's relying on his senses for the review and doesn't want to influenced by the brand name on some crossover component.

It is the difference between a paid listener and an engineer. It’s that simple. Some people will pay 100X for something they can plug in over 2X that is better.
Keep it up!

You want more drama? 🎭 Please make upgrade kits for Tekton speakers 🔊

A truly genuine dude. No bullshit. I used to put sound system in peoples' homes in the 80s. I used to tell them then that the most important part of your system was the room!!! I like this guy, not hidden agendas, just trying to educate people who think that a bluetooth speaker is the best way to reproduce music with accuracy. You will never hear the hard work that the engineer put into the mix to get the most realistic soundstage of a recorded guest without paying close attention to how that complex waveform gets to your ears. Built to a pricepoint. love it. If you take ego out of the equation of most "reviewers" they would see that you are indeed correct!

Andrew said that he doesn't think it makes sense to buy speakers that need to be improved later, but it makes more sense to buy speakers that you like right from the start. And what does it matter what's inside the speakers if you like how they sound? Then everything will be fine. If you like speakers in which the manufacturer has used cheap parts, that's your problem.


I'm a customer of yours both products and upgrades love what you do and the fact you share your knowledge. Your not trying to bull us. I have enjoyed learning from you and have upgraded my cheep speaks that now sound better. Thank you!!!!

Saying parts quality doesn't matter in audio is like saying food quality doesn't matter in cooking.

I'm so glad that you made this video. I'll be putting together a system in a few months. You are now my #1 choice of speaker manufacturer. I think you really clarified some misconceptions. Thank you!

I'm a fan of Andrew Robinson and watched that particular video, and I have to say he's wrong. I'm an electronic engineer by trade and someone who loves audio. It really matters to me the quality of the crossover and the impact it can have. Speakers that have high-quality crossover parts are unfortunately overpriced, so upgrades can be an affordable route without the financial impact.

Qudos to Danny for taking the high ground. He used it as a teaching opportunity, not getting sucked into a spat.
I was dubious about being able to hear changes in components... Until i tried it.
It really is astonishing what the human ear can differentiate.
He also understands the psychology of the diy audio enthusiast...
Some people throw money at something and want to believe they have "the best". It bolsters their ego somehow and makes them feel superior.
Whereas the diy guy sees it as an incremental journey of improvement... With no expectation of ever reaching perfection, but a determination to keep striving for it.
It's an interesting hobby, not a consumer fashion statement.

When you took off your glasses and zoomed in on the affiliate links…
Epic!

The alleged shill reviewers sound like timeshare salesmen
Danny went through his bona fides recently and yet he has to address the alleged shill reviewers
One reason I build my own speakers is that the mark-up is insane and you generally get crap parts
Ignore the shill reviewers

Danny, I appreciate your content and I appreciate Andrew's content. I also get that Andrew seemed to be the first one to fling the poo so here we are. I think right here says it all 33:50 --what I mean by this is, you're going to have to accept that your audience and Andrew's audience aren't necessarily the same person. That stated, there are people in Andrew's audience who might be interested in your level where the reverse might not be as true. Do you see where I'm going with this?
Not everyone and in fact most people (including myself) who appreciate audio are going to have the budget or the lifestyle (or let's face it, a significant other that might be less passionate on the topic) that allows them to have a dedicated room and automotive level budget for high-end audio. I'm a musician and talk about gear, I own most of the things that create the sounds that audiophiles gush over. You think my Hammond A100, Rhodes Mark I Seventythree, 50's era Wurlitzer, Amps, Mics, Basses, Guitars, Synths and all the outboard gear live at home?? Wooo the divorce papers would be a comin'
At home I have a decent sound system with some Bob Gross Super TLs and a simple Marantz 2235B. My turntable is a Kenwood KD550. My streamer is a Bluesound Node. The speakers are off the wall but there's no sound treatment going on, my 90 year old raised foundation, flat walled, hard wood floored home resonates like crazy (its kind of fun actually). Could I do better? Absolutely I could and probably will down the road BUT do I like what I have, YES. Do I know it's not perfect? Of course.
Andrew is coming at it from a little more of "don't sweat the small stuff" approach. While he might be making money with affiliates, remember, the measure of responsibility you're holding Andrew to, is your measure, not his. His measure aligns more with the casual listener who maybe wants to get into the hobby because they love music but isn't interested in the micro-science and precise levels of engineering that you are. He's listening and measuring speakers in an imperfect environment because that reflects his viewers. That's what makes Andrew, Andrew and you, you. I mean we're in a world where 98% of people are listening to their favorite songs on cell phone speakers or horrible earbuds, I give anyone credit who wants to hear something in better fidelity than that.
I believe what Andrew is getting to are people that are interested in the hobby but they want the systems that blend into their lifestyle, not consume it. Maybe one day they'll really want to get into the quality and engineering of it, that's when they'll find you. That's exactly how I found you.

I watched about 20 seconds of Robinson and that was enough. Very telling he doesn't understand industries selling billion$ of upgrades for headers, turbo chargers, chips, and 1000's of upgrades for cars that were already 'just fine'. He doesn't understand that piddling around with this stuff is our hobby a lot of the time and it's fun and satisfying. It's not just audio, is what I'm saying. People love to try to improve things they enjoy. Poor guy probably never stepped into a Radio Shack back in the day. He's a video version of Stereophile magazine, which I loved in the 90's until it just became a pump for the overpriced audio companies, which became boring.

You did a good point!
The room is a big part of a system. But still i yet have to find a trustfull source for correct room treatment guides. Any video is marketed with brands. I step out and quit after i hear. Our sponsor blabla-Audio….
Without a shop its impossible to get it to the right direction nowadays. There is so much wrong things out there.
My take on it…. Maybe i miss something..
One last thing. Less than 1% of ppl wanna have dedicated listening room. There is always a canvas or a TV between the speakers.
Its bad i know but its reality! No one focus on things ppl want.

The guts ARE important. The high end audio industry is NOTORIOUS for not only snake oil but "reviews" that often feel like paid ads. Manufacturers have privately admitted that when they set HIGHER prices, their products are perceived as better by the high end industry in general. The budget of a product allocated to cosmetics alone can be a significant chunk of the selling price.

If you’re happy with your speakers stick with them and don’t worry about upgrades. If you want more or are interested in exploring, the upgrades are for you. I personally enjoy the educational aspect of upgrades. Like a lot of things it doesn’t have to be one or the other. Different strokes for different folks.

Andrew Robinson's point seems to be that upgrading a speaker's crossover may not always offer the best value. After purchasing speakers and then investing in crossover upgrades, you may have spent enough money that it would have been better to invest in a higher-quality speaker from the start, avoiding the additional work and hassle. While DIY speaker projects can be enjoyable and are a valid hobby, for the average person who may not want to invest the time and effort, their money could be better spent elsewhere.
Although crossover upgrades can make a difference in sound quality, the improvement doesn't always justify the cost. Spending significant money on upgrades may only result in a marginal improvement, without addressing the inherent limitations of the speaker's design. True innovation in speaker performance comes from a ground-up approach that considers the entire design, not just the crossover. Ultimately, how a speaker measures in performance is often more important than individual component selections when it comes to how it will sound. This isn't meant to criticize anyone's choices but simply reflects a personal opinion. Cheers!

Well said Sir!!!!. As always very professionally done.

Kit speakers or custom are always better than mass market.
Andrew gets commissions will say anything for money

For me there are a couple of good reasons to do an upgrade:
1: for the fun of it, on a set of speakers you like but know are flawed (likey you've had for a while or have bought cheap second hand.)
2: as a hobby project to resurrect a vintage set. You know, bring them into the 21st century.
3: As a repair job where wiring and/or other internal components have gone bad and instead of replacing, you'd rather repair and upgrade.
Because you want to see how good you can get a set of Sony SCSS-5's sounding.😅 (Falls into the hobby project)
However:
Simply 'fixing' a modern speaker you just bought new... This is counter productive. In this case I agree with Andrew. Better to buy the speaker you like the sound of and be done with it. Doing a good audition of speakers is so important here. Andrew often says: 'Remember, the only person who has to like the sound of your system is you.' i feel this is where he's really comming from. If the crossover is a pice of tin foil and steel wire wraped around a nail and it sound good to you👍. If you don't like the sound. Don't buy. His reviews are no targeted at the diy/hobbiest. They're often at the mid-to-high end buyer that wants to know how it sounds, not really the underlying nuts and bolts.
Keep up the good work Danny and GR team. I always learn something.

This video popped up on my feed and I thought Andrew Robinson sounded familiar, I looked through my history and had started watching his video "Do Home Theaters NEED a CENTER SPEAKER?" at one point and remember being extremely off put by the weird interview sitting in a chair style with blurred background...Strange. But to each their own. I watched for about 5 minutes and couldn't take his voice or the female background voice anymore... I've always been of the mindset, if you don't like it, don't buy it. If you don't want an expensive cable, don't buy it. If you don't want to buy a speaker upgrade, don't buy it. I'm just getting into the DIY speaker world and can't believe how much smack talk there is about this company. I bought a center channel kit from GR and couldn't be happier. Questions were always answered, no pressure was ever put on me, just great customer service and a quality product.

All I know is, I have speakers the manufacturers highly regarded ,once I tested the speakers , was quite disappointed and wanted to return them. I found out you had an upgrade kit for those speakers I bought and installed the upgrade kit , am I glad I did ,I can almost melt into the same music after the upgrade that I was disappointed before. I trust your work because the results is definite, stay unwavering some of us that know better got your back through your proven work, those that do not know ignorance is bliss

I think you missed his point and made his point at the same time. Here’s an analogy. He’s saying buy the car you like and if you don’t like it trade it in for one you do. Your saying buy a car if you don’t like it puts new rims, wrap it, put a turbo on it and so on. It just different preferences.

I'm really glad to have run across GR recently and appreciate what you do and how you do it. It just makes sense and sounds like the truth. well said and the high road taken. you clearly care about the quality of music reproduction and the experience. Its the difference between what an audio engineer and a salesman can offer. for a sales type to say he doesnt care what's in a product? fine. but there are those who do care, because it matters, and want to learn and improve and arent afraid to learn, as opposed to that smug, know it all attitude (usually a cover for insecurity). no one benefits from that but the salesman's ego. great work.

He is true, only sound matters to the customer. For 99%. The 1% would like to know. But the 99% is where the money comes so ask again who cares. Not me too. I do know the speakers i use sounds good. Iw had few, from genelec G5 to "the ones" to few Klipsh models to Jamo one to and so on. Triangle antal stays. For now :D You can upgrade the crossovers and what ever, that is like changing engines intakes and adding turbo to the car, its not for everyone, maybe to the 1%.

Soundstage/Imaging, a genuinely Holographic presentation is the single-most important factor in EVERY aspect of my audio equipment. Across the board. This is coming from someone who began selling high-end retail audio back in the 80s. I've had all of these years to determine what provides the most enjoyable experience (for me).

I stopped watching his channel long ago. Quickly became obvious what his understanding and skill level was of audio.

Danny, you burst my bubble! I thought that I was the only one placing components on the positive and negative side. I feel somewhat inspired to make a crossover using a buffalo nickel as the base and using cheddar core inductors with twine insulated wires, and a gum wrapper to conseal the contents. Definitely a Mickey mouse job!

Andrew & Kristi.... I love your reviews. I get what you're doing and why. No issues with it at all. BUT..... There's a lot of validity to what Danny is saying. I realize your not engineers and just want results and caring how the results happen isn't important. I get that we live in a world of buy good or buy better. Not picking a side, because Danny knows I'm brutally honest.
Danny.... something you didn't mention. The expense to upgrade a speakers crossover isn't always going to provide enough "leveling up" to warrant the cost. The gain can be fractional on some speakers and simply isn't worth it.. Some speaker can really use an upgrade, but not all and not all are worth the investment.

I'am a hobbyist that was buying from Zalytron on long Island back in the day. I had "the books" and some software but learned that it was much better to send the drivers out to madisound, have them analyzed, and have the crossovers designed by people that really knew how to use LEAP. That being stated, It's obvious i got my feet pretty wet and the few people that are getting into this now, should really carefully watch, listen, and understand your vids. They are 100% accurate. If I was to do another build (which im not), I would send the drivers to GR, or Madisound! But it gets to the point where one would be better off simply buying a proven speaker other than wasting countless hours trying to re-invent the wheel! Edit: as far as your upgrades, it's a great idea and small investment for people that want to keep and upgrade their "vintage" speakers, or even "fix" the newer ones that they may own! Thank you for such great vids!!!

Excellent explanation of how parts effect sound. I built a pair of your Brutes with the high end options. I could not find a speaker anywhere that performs as well for the price. I have built several pairs of speakers including Open Baffles, which are my favorite. Parts do matter! Facts are often difficult for people today, Danny you need to put more feeling into your reviews so the wannabe's can understand what your offering. Andrew is clearly a very sensitive man, he needs a hug.

You, sir, are a gentleman, a professional, and most likely a genius. Andrew is just a listener. But I really like his interpretations on some things. I’ve actually purchased some of the things he recommended which leave me very happy with the purchase I made however, after watching your channel I bet you things can get better.

I stopped watching his channel a long time ago. If I had not, going out of his way to demonstrate ignorance about speaker design would have done the trick. 🤪

My GR-Research crossover upgrades were my first introduction to how speakers should really sound and led me down the right path in my audio journey which has brought me many hours of enjoyment. In my opinion after experiencing the upgrade experience myself, anyone who thinks negatively about it doesn't know what they are talking about or are biased for some financial or other self interest.

well in a way Andrew is right. There is a clear segmentation in the audio equipment market. The DIY and tinkering aspect of the hobby is not to everybodies liking. And for those, who don't want to bother with this aspect, it's probably not worth it to do an upgrade. Andrew is calling this a boutique market (and it surely is, if you want this kind of parts quality from stock speakers). But even Danny kind of agrees, that it's often better to start from scratch (with one of his kits), than to try and fix something that never was intended to reach this kind of quality in the first place.

Humble honest and great points. I have been around “high end” hifi with my dad since the 70s. I’ve worked with some people who are very well known in the industry. This is not bs. I built a power supply and swapped caps for a year before I landed on the right filter caps. When it comes together it is amazing.

Recently I completed the Dennis Murphy Mod for my Pioneer SP-BS22 bookshelf speakers. I can say there absolutely was a great improvement in sound. The sound stage is now more expansive and deep with a smoother high end. I learned from practical hard proof: Crossovers matter. The original speakers were quite nice for the price but the upgrade took them to a new level.

As a guy who enjoys building DIY computers, I totally understand where you are coming from. There are different audiences for for audio just as there are for computers, and the "truth" will change accordingly for each group. There are enthusiasts and there are DIY hobbyists. What makes sense for a DIY guy who will welcome the challenge of upgrading something and appreciate the results a lot of times will not makes sense for the person looking to buy something and be satisfied out of the box.

I have listened to both of these men. I will continue to listen to both of these men. I do not see this as a reason to "pick a side" or turn this into some street beef-type situation.

The upgrade tech talks are the best bit. I've learned so much about speaker design from this channel. The keep it simple design philosophy in GR-Research really works. I understand the acoustic physics, but the hands on design / measure / iteration approach is the best.

I admire both Danny and Andrew. I think it’ll be educational for Andrew to visit GR and bring his reviewer expertise to Danny. In this wonderful hobby one can always learn.💎💎

Holy cow did I learn a lot on this one. Thank you!

Gosh andrew’s facial expressions are so smug. He should at least try to hide how pleased he is with himself.

It's NUTS. I just upgraded my first crossover on a pair of 60s Sansui SP-200s. Craziest thing I've heard... I honestly never thought it would make that big of a difference. They will blow away a lot of super high end stuff now.

Crossovers are the weakest point on any speaker that are build for price point what ever is the price point, period. I upgraded my speakers crossovers with better components and it was BIG upgrade! All those cheap sandcast resistors, electrolytic capacitors and iron core coils removed with better parts was game chancer!

Very classy response Danny you just showed how much of a gentleman you are. I was watching the whole time thinking invite Andrew invite Andrew….and bam! 👍🏻

I find it fascinating that we are being told that you need a special room set up to listen to your speakers in the real world are a least in my world our entertainment is usually set up in our living area , everyone doesn't have the luxury of have a dedicated listen room

Hello Danny, this is Anthony from DE. Outstanding video
Very informative and one of your best videos!!

Danny you should make a test set on encores and use cheap crossover parts send it to Jay. He would be a good guy to do a fair comparison . Do a downgrade to prove your point.

18:14 "what makes it sound different is how much the signal is degraded" is a good argument for active crossovers, I'd say. Basically then there's nothing between the drivers and amplifiers except for some (usually very short) cable.
I can say this much for a fact - every single time I've had the chance to compare actives to passives, regardless of price, the actives win. Much more dynamic and "fun" because the amp has full control over that driver with no crossover components that store energy or add resistance between them.

12:20 Andrew: As an electrical engineer and an audiophile, I CARE about the crossover network design and components.

Danny and Hans are about the only audiophile guys I trust on RUclips any more. This has been a tremendous video. And I remain a very happy GR Research customer.

❤Andrew, his reviews are straight talk and resonate with 99% of us hobbyists who despise the hate filled forums snobbery and people telling what me what I should like.
Honestly, a bit arrogant to think he’s talking about you, he was referencing his career and what he’s seen over the years.

I used to watch Robinson’s channel. Just his attitude toward the “I don’t care what’s inside of a speaker.” It honestly made me very disappointed and upset to hear him say. As I said on his page “I care what’s inside my speakers.” I enjoy replacing caps let alone researching what individual caps sounds like even within the same brand! Please Keep up the excellent dedication to our speakers Danny!

Another point is, ,in general, the higher end higher cost speakers tend to use better parts in the x-over, wiring, connectors etc.. Why would they do that if it made no differeince? PS audio speakers for instance. Nothing but high quality parts.

I have pair of Timekeeper 2’s from Tyler Acousics designed by Danny. I hear new things in music I have been listening to for 50 years!! Amazing sound & detail. Danny is the real deal!!

Danny,
It's real simple,... tell those guys to whip out a dual trace oscilloscope, and a high quality signal generator...
Set the o-scope up for dual trace mode, as well as your divisions for an audio time based grid, and then put your signal generator on square wave mode..
Place one "trace", or probe directly to the output of the signal generator, then pass the signal THROUGH what ever component you want to do diagnostics on....
The scope will (WILL) show the differences between iron core inductors, sand cast resistors, and electrolytic caps VS using HQ AIR core inductors, poly FILM caps, and wire wound resistors...
I've een in the industry for decades, and believe me- this simple O-scope test will show the differences in ringing, smearing, and time delays..

Literally decades before I ever heard about GR Research I knew that upgrading crossovers can make a tremendous difference. Redesigning poor crossovers is beyond where I take upgrades, but obviously a poor design is best replaced by a better one. No question.

i think you and Andrew are on more of the same level than you both think. the niche market he's referring to is the speaker "hot-rodders" like yourself. nothing wrong with it, just not for everyone

This is an excellent account on the importance of parts quality in the signal path. Well done.

I believe Andrew once said that speakers don't break-in over time. I stepped back from him after hearing that opinion.

Danny is right about Andrew. I did upgraded two pairs of tower speakers of KLIPSCH on my own before I knew about GR Research and those speakers turned out so much better than original parts

You're always criticised by those who do less never more. These companies pay very little into research & design & expect consumers to just such up the end product.

Like me, I'll bet a good amount of people do not have money to spend on audio. I've built all my own gear and at one point decided on spending $450 on a pair of vintage B&W 602 S2's and $300 for Danny's upgrade, I don't think I could've found anything comparable in that price range. Thanks Danny for helping plenty of us out!

Andrew comes off as a Best Buy sales guy in a previous life...

Phenomenal explanation and analysis. Thank you!

Andrew’s “who cares” response came across as hugely pompous to me. Big turn off.

Andrew thinks that the B&W 801 D4 is a fantastic speaker. It's also obvious he's bought and paid for! I'm a Brit living in the States since 1990. This speaker was my personal "Holy Grail" and I bought a pair earlier this year. I can tell you I have never been so disappointed in my entire life. They are getting changed out, but as of late I'm not sure what to.

Thanks for the video, I'm still loving my X-statiks.

Wow!! I learned a lot about speakers from you. I understand why someone would ask what's inside the speaker.

Andrew said: "As long as a speaker sounds good, I don't care what parts are used inside it". His logic is sound, as the end goal is for a speaker to sound good.
