Jay I consider you one of the most important audio reviewers for two reasons. You are young and you took the time to listen to a very large sample of high end and vintage gear before you really ramped up your review channel. Most reviewers at any age have relatively small sample sizes of the gear they have actually listen to. They don't know what they don't know. As a 60 year old audio guy I think it's critical to high end audio that younger enthusiast like yourself carry this forward. But I would suggest your read on Danny was misplaced. He basically invited all camps to join him and see were it would lead. Sure it came off as arrogant but when you get older you find less time to sugar coat your thoughts. When I look at the room treatments, good quality speaker stands, audio platforms and other things you are using it would seem to me that you and Danny are totally aligned. So why would Danny send his cable or speakers to some reviewer that did not believe any of these things matter. Yet you interpreted his bluntness as a personal insult. This also seems to be motivating you to hyper scrutinize any claim GR makes at a level you don't seem to do with any other manufacturer.

[@Jayiyagi]

@@theaterboyeBay thanks for the comment. I do not have any intentions to hyper criticize anything. I just wish to thoroughly check the claims as I am personally interested. Many are also curious as Danny does put out many claims out there. I told Danny in an email that I will be fair in the assessment of his product and he said that he trusted me to do just that. I have no interest in betraying that trust and the trust of the viewers JUST to discredit or take a shot at Danny. I’m here for audio and I will stay true to that fact and passion. Thanks !

@@Jayiyagi Watched a bunch of Jay's reviews. Was anticipating this one, having actually heard a cheap (non upgraded) sample. Best speaker ever?!? No not exactly. Super impressed for the parts and price. Yes hard to beat. After the podcast and back and forth, this introduction and feedback in the comments is not surprising. What I believe stands out to people that have seen Jay in action is that he is overly eager to find avenues to discredit GR's creation. Measuring the purity of the connection, getting the accuracy through 3rd parties. I'm all for it, but he has not ever come close to considering doing this to his retail reviews (nor the CSS) It feels like you got the horse before the carriage and now you try to save face. If you would have only have approached this initial view as all your videos.... Hard to go back from here.. Danny is an A$$ calling people out. He comes across very arrogant, but clearly provides great value for Sound in the DIY market. With Jay coming in hurt and tainted does not help anyone.

[@WillyLax24]

I have recently gotten into designing and building my own speakers and I like learning as much as I can on the subject. What I don’t care about is “drama”, so I really appreciate you taking a professional approach to this review. For people like me, a speaker I get to build myself is actually a good thing, not a bad thing. I get for others that it is definitely a bad thing to have to build the speaker, but I like to be able to make things my own (picking my own paint color or wood finish).

[@Justwantahover]

I have also been building speakers since the 70s. But then I was just putting drivers in boxes and designing crossovers (like most speakers). If I just did that now, I would only build one set. But cos I don't just do that, I have built several sets in the last few years and I'm going to probably end up selling some. The concept is a med/treble open driver mounted on top of the box (either FR or coaxial driver) and a 10" woofer in the box. I have some AU $2,400 B&W 706 bookshelf speakers (to get an idea of how a speaker should sound). My made speakers completely smoke the B&Ws! Yet the B&Ws do help a lot (especially with bass that varies in the room with my movement). And they improved my speaker hobby immensely! Yet I don't like them, with a slightly "muffly" voice sound. But (really) that's a minor detail, generally, a reference of the bass, med, and treble levels is what really helps me. That's the important thing! Recommended if you haven't got a soundproof room and all that gear. So I make my made speakers sound a bit different but not too different and mine sound way better, for me, at least. They are dipole with the sound coming out the back as well as the front. They sound like panel speakers and the med is incredibly clean, compared to normal speakers (not one sour notes on mine). But it's till hard to get it but not as hard as normal speakers.And if there is any echo in a recording, you are going to hear it! You are in with the band! And being point source as well as dipole, it's holographic off the scale, sounds come from nowhere! 😂 Put a woofer in a box with a big inductor on it and a 5" Tang Band or Fostex FR driver mounted on top of the box (sloped back so it's not so in your face). You can use Blue Tack for temporary mounting solution. I use zip ties and eye hooks. 😂 I tried the setup with no crossover filter on the 5" FR and sounds good, but a 100 mf cap on it is recommended for more power handling and that gives more bass for the woofer. If you are like me and want the best sound, you can make a crossover filter for the FR. I use AU $9 FR and they need the highs to be kicked up, with a 2 mf cap and a small resistor iñ parallel with it (to make it simple). But I go full out and have a few parts on the 5" open driver (including an inductor for less upper med). Definitely well worth a try, they sound hi end (especially with a large woofer). More impact.

Peerless / Vifa / Scanspeak have been making great performing and cost effective speakers drivers for a long time. The 1st set that I built 51 years ago used a 5" Peerless mid-woofer and a Audax dome tweeter and had not one of my kids decided that the domes should be flat I would probably still be using them. My 75 year old ears that spent 15 months on an M60 main battle tank are not that discerning and anything above 12,000 hz is fiction to me.

[@Gabster1]

Hi Jay Love your Chanel, I have used the Ali-express cables for a while and did a small video about them on my Chanel Something must be wrong with these Cables some possibilities to check 1) Mislabeled polarity 2) Not all the strands are soldered in the termination sometimes they are sloppy. I suggest cutting the banana plugs out and use the bare wire 3) A bad example of Ali-express cable check that each strand is about 0.75 mm in diameter (0.03 inch) the total of each 12 strands (not 24) bare copper should be 3.5mm. (0.14 inch) Each strand should be made of multiple thin strands not solid 4) Bad connection with the speakers not tight enough accidental polarity swap. 5) May be stuffing the cable with a rope ( like GR shows how to do it) , does make a difference I would try that at the end. Very Curious how it goes I would really hate to have to buy his Cables we must find the secret :)

[@vinylcabasse]

how do the GR cables and the ali cables measure as far as resistance/capacitance/inductance? something seems fishy about the aliexpress. i'd love to see a number that can be correlated with the cable and why it might sound different.

I look forward to your review of their speaker and cable comparison against Blue Jeans, which I currently use.

Could the cheaper cables be incorrectly marked to be out of phase? That would explain why such a big difference in low end if it turned out to be the case.

[@flynow5614]

I built my GR-Research cables. First point it was a fun project. 2 They sound great. End game for speaker cable for me.

[@bart7695]

About the speaker cables: It's either the connectors or the core. GR uses a thick rope as a core to stretch the cable and make individual wires cross at a larger angle. Lefthand rule: less interference. Put a rope core in the Aliexpress cable, change the connectors over and find out.

[@markcarrington8565]

You’re right, although I understand that Danny slides a PTFE tube as a core. This is available from aliexpress and adds about 20% to the cost of the cable overall. I know because I did it. No idea how mine sound against the GR Research cables, obviously, however, my cables were a significant upgrade over my old plain copper cables.

[@pliedtka]

The higher gauge wires almost always sound as if the sound was fuller and a bit more bass wass added. It's not night and day difference, but it's noticeable. The same thing happens when someone upgrades crossover inductors in the woofer circuit from 16ga to say 12ga, but even 14ga inductor with it's 60% impedance of the 16ga makes a measurable difference during freq sweep on woofer's connectors. Generally the total series impedance of wires and crossover shouldn't be more than 15% of the woofers impedance.

[@guyboisvert66]

You forgot about the copper: The best is Pure OFC. The Aliexpress cable are probably made of cheaper copper mixed with other metal(s). Insulating material is probably different too.

[@HardCold-Alquan]

@@guyboisvert66 I have some on the way and it is better than OFC copper, it is OCC copper. Those cables sure look thicker than I'd prefer, but i'll see. I have 10-gauge right now and I don't want to go any lower. It was hard to do the math to figure out what gauge these Ali's were and the seller could not convert the size for me either... I had the 24 core.

[@gustercc]

@@hurkamur1 that’s some compelling evidence you’re presenting there.

[@chrisburn7178]

I think the simpler reason that Danny doesn't measure below 200Hz is pragmatic: in order to eliminate room reflections the measurement software takes maximum 5ms "slices" of sound, which means that anything lower that that frequency can't be measured as you're not even capturing a full wave. As far as I know anyway.

[@andrewskaterrr]

The main reason is in room response will be entirely based on your room. To measure below 200hz you need anechoic/outdoor/spinorama measurements

[@JimBob_1975]

Are you sure that polarity markings on the cheaper cables was correct? Had someone fitted a red connector on the end of one core and a black connector on the other end of the same core? Is it possible that as a result your speakers were out of phase?

[@alcophone8072]

I probably missed it, but if the GR Research cable has tube connectors and the AliExpress one has banana plugs, how did you test them on the same speakers?

[@ericschultz9925]

The connectors and the damping from the added core that Danny adds.....can make all the difference in the world. Remove the connectors from the Ali cables and twist all the bare wires together and cram them in the jacks on the amp and speaker......it will sound worlds better.....then put the same core into the middle of the cables and listen again. Not saying the wire is identical.....but if it is.....connectors and damping can make a ton of difference.....everything makes a difference.

A lot of electrical cable made in China is aluminium based with copper plating. Of course, on must remember that high frequency is conducted on the surface of a conductor and if the Chinese cable only have a few microns of copper plate over the conductor then obviously the character will be a lot different to a solid copper cable. Chinese wire is also mostly hard drawn, which is different than an annealed copper or a single crystalline cable. So yes you are correct in saying a cable is not the same if its construction and material used is not the same, at higher frequencies this does come into play.

[@andrewskaterrr]

Luckily the majority of speaker cable isn’t copper clad

[@onebylandtwoifbysearunifby5475]

Woofer weight is a myth. Some manufactures ADD weight to their woofers (especially rampant in car audio). In reality, if the woofer is well designed and the materials are well chosen, the weight is not often relevant, not like people assume. Big magnets are like big car engines: something already went wrong when you need excess power. Make your car (or speaker) lighter, and you can get around the track faster (accelerate faster).

[@gregorymorrill7558]

Woofers don't take corners. You can only make an rough analogy to acceration and braking. Reality is that motor strength is very important, especially in the woofer of a 2-way speaker that is tasked with handling some deep bass and thus making some pretty deep excursions.

We certainly don't all agree but we all are in it to share, learn and improve our sound. Love the Ali-express bit too.

@@donalddietz4755 pure copper is an excellent conductor, however it makes for a poor (traditional) connector. It is not very springy, so it is easy to deform the material. For a pure copper banana, it's so soft that (depending on the design) it can easily lose the pressure required for a quality connection. Tube connectors design their way around this limitation. This is why most bananas are brass (more springy) or even steel (gold covered even). Brass and copper will oxidize in normal humidity, so unless you want to frequently de oxidize / clean them it's a good idea to add a more stable surface.

[@stephenscharf6293]

Regarding the woofer driver frame material: it's composite because its 1) mechanically stiff 2) light and 3) non-resonant. Oh, and it doesn't ring, which is probably it's most important attribute. Personally, I don't understand the concern of _what_ something is made of; what matters is _how_ it functions. I'll just add that F1 cars are composite as well. Regarding the cables, one can't draw informed conclusions of a speaker cable simply from what it looks like, the quality of the materials, it's geometry (how it's wound) and the....dielectric (insulator) matter also, and, most importantly all these factors _interact,._ just as Time and Temperature often interact as factors in a chemical reaction. The Ali Express cables likely use PVC for the insulator, which has a notably negative impact on sound qualty, the best-sounding dielectric material is FEP (not Teflon). Again, what matters at the end of the day is how it *functions* (i.e., how it sounds). Regarding the tube connectors, not only is it important they are made of pure copper, but low mass as well. Danny's products are very well thought-out with respect both functionality, but also they're designed to _maximize_ interactions that contribute to functionality and sound quality and _minimize_ deleterious interactions that impact sound quality. The issues I see with almost ALL reviewers* is they approach product functionality from a very simplistic frame of reference: that is, single factors by themselves are responsible for functionality (in this case, audio quality), without giving any consideration to the fact that design factors, materials, and control variables often _interact._ I can tell you that as someone who spent 40 years working as a professional scientist and 10 years as a Design for Six Sigma Master Black Belt, this overly simplistic perspective/viewpoint of single factors, functioning independently by themselves, is almost *never* how the REAL WORLD *works.* (*-they also don't perform any statistically valid measurement systems analysis [MSA], either, in fact, they don't even know what MSA is, but that's a story for another day).

[@MrAKbass]

There shouldn't be much of a difference between measuring with MLS software or measuring in an anechoic chamber. MLS removes the reflections, the size of the room determines the time window and therefore the lowest possible frequency one can measure without reflections. The frequency lies somewhere between 200 - 350hz (depending on room size), which is low enough for designing proper cross-over circuits. Most stuff below 200hz can be simulated quiet well since the cabinet's "shape" doesn't interfere that much with these low frequencies. I use this method for all of my designs. I know there's some negativity around GR Research and I know Danny can be pretty direct in his communication but I must say that I agree with a lot of what he has to say. Btw. I have experience with designing loudspeaker for about 35 years, I've build stuff for home audio, studio monitors and instrument / PA loudspeakers.

Look at those beautiful solid steel speakers stands in the back, they’re so beautiful but expensive.

[@NeilBlanchard]

It may be that the spacing (fiber?) that is inside the cable is what is making the difference?

[@RennieAsh]

That's interesting about the cables, sounds like a fun diy project.

[@rmzidann]

Do you send all speakers for anechoic chamber testing and copper analysis of the binding posts? 🤔🤔🤔

[@Jayiyagi]

RE: anechoic chamber Yes we do for the majority as long as logistics allow it. It is usually reported via soundstage website for measurements as I am just making sure everything is OK from engineering perspective (that there is nothing terribly wrong) I often summarize relevant points in accordance with my listening tests :) RE: binding post No manufacturer really emphasized copper posts like GR did so this is something new for me as well

[@rmzidann]

@@Jayiyagi . That’s good to know. But then again I have never seen you get the drivers out and comment on driver “quality”. Would you consider opening up the sonus Fabre speakers and looking at their drivers and their crossover?

[@Jayiyagi]

@@rmzidann actually. I used to take the drivers out and show internals often. I do comment on driver and component quality of speakers and gear often in my videos. I stopped with opening up speaker as much unless it is DIY because nowadays there are many internal cutaways by manufacturers. I do take a look inside at times to verify the cutaway pics BUT sometimes it is not viable like in case of the sonus fabers - it is annoyingly difficult because there are no screws outside and just not worth damaging such an expensive speaker that I bought. I don’t strive to disprove manufacturers or be this solution to everything. Sometimes I can’t provide what you are looking for - I just share what I can.

I look forward to your comparison with blue jean and other commercial cables. I was thinking to buy the GR research cables to replace my DIY cables and am interested in your impressions.

[@JosephTrinh]

the cable might still be the same kind, I think. Just the connectors that make the different in terms of sound. do you think?

[@AT-wl9yq]

No, its the whole cable that's making the difference, not just the connectors. Whoever made the cheap cable used the same mesh that holds everything together. Anyone can buy that stuff. What's inside the cable is what really matters. That's why most of the well established cable manufacturers don't use off the shelf materials like that because counterfeiting is a huge problem.

[@JosephTrinh]

I bought the raw bare cable and striped all 24 strains, inside the mesh looks legit. Can not tell if it’s 100% copper or not, but definitely heard a different making the switches from Canare 4s11 cable to this aliexpress I bought $120 bare cable for 20 ft.

[@stevieg2755]

[@mpix8302]

Dude, you really should spend some time on the DIY forums, and read the books and magazines for DIY'ers, learn what's what. Ask Danny what rope to buy at your local home center and thread it thru your Ali Express cable, see if that makes them more sonically equal to the GR-R cable. It should. With a braided or twisted cable, the closer to 90º X intersections of the braid strands and the more air (space) between strands the better the sound will be, that is the reason for Danny threading rope thru the center of his cable. Re Tube Connecters. I feel Danny didn't tell you the whole story. it's not just that they are pure copper (pure Silver would be better), plenty of pure copper binding posts on the market, it is the lack of metal that makes them good. Minimal metal will be better than a huge chunk of machined copper binding posts. Think WBT Nextgen, and Eichmann binding post. Also, you're wasting your time with the jeweler, if Danny says they are pure copper believe him. If you want to nitpick send it to a metallurgist for grain structure and purity testing. Anyway, they say nothing good happens between 2am and 7am, and it's almost 4am now so that's all you're going to be getting out of me on this, I don't feel like proofreading and backing up statements with the science behind them at this hour, sorry. Peace.

Hi Jay, yes Danny could have worded his video with a bit less intensity , but I get what he was saying in regards to a good room to let one hear a speaker to it’s fullest . My old loft in Montreal was a great sounding room and a mid hi system sounded better than hi end in a small bad room. System was, Vandersteen 5, vtl 150 power amp, Aesthetix preamp and more. Thanks for sharing you listening experience.

I like this video. Jay is going to be a genuine detective. Look forward to seeing if the Blue Jeans are as good as GR-Research cables.

[@robertbreish8182]

Paradigm Founders bookshelves are just absolutely stunning. Indeed they are truly a very special speaker. I’ve got founders paired with an Anthem MRX 740 and it is a match made in heaven. Just rewires my entire HT with Kimber 8PR which I admittedly wasn’t sure I was going to hear a difference. I was very wrong and the founders sound completely different with the Kimber Kable and I didn’t think they could sound any better. Can’t wait for your review of them!

[@SimplestUsername]

You should try splicing a GR Research tube connector on the Ali Express cable and see if that improves it.

Nice vid. I really favor the A to B blind comparisons. It may seem harsh but ultimately we all want to know what's best and who we can depend on for quality products. I don't listen to music in a chamber so I don't care about that. I'm more interested in how they sound in your day to day listening room.

[@jwilson086]

Danny may chime in as well but in regard to the composite material that the woofer frames are made from, that is by design. Danny likes that they are non-resonant and they are also surprisingly strong. He had a picture of one of his drag cars driving over one at some point I believe and they didn’t break. Looking forward to watching more as you continue to listen to them, especially the blind A/B tests.

My take on this is he cheaped out where it didn't degrade the performance. Which is a good thing. I wonder if these drivers are the standard ones or ones that he's using due to supply chain issues, they do look a little different. Could be presented a little better with less cheap plastic.

[@davidsykes2825]

The way a speaker looks matters. I understand too that appearance can have some subjectivity. These speakers are so cheaply designed though from an astheatic perspective. The design (astheatic design) is part of the quality and skill of speaker design. Even if it is over priced by many manufacturers, at least they understand the importance of that aspect of the product. It may make no technical difference on the sound but it can make a difference on how the speaker makes you feel. And in turn, how you feel about the sound. This may not be true for everyone but I think it is for many.

[@behappybevegan]

Compare the cables with basic 4mm copper ones.

[@hoth2112]

I ordered some 8TC-based interconnects from Ali-express for comparison recently cuz for $30-$35 why not? They sounded like crap. Just annoyingly bright, even after putting some time on them. Come to find out, after further inspection, over half of the strands were just shoved into the RCA end. Not connected to anything, nor properly insulated to prevent shorting out against the barrel. They look nice for the price, but definitely not worth killing the equipment.

[@Jayiyagi]

I honestly don’t know what they do to make it sound this obviously bad. Sounds like something is terribly wrong but not enough to notice if you didn’t try any other cable… very weird

[@AT-wl9yq]

I see a couple of problems with this. First, 8TC is a speaker cable. I have no idea why someone would want to make an interconnect cable out of it. Why not clone a pair of Kimber interconnects instead? Also, even though they may be able to get the cable to look like an 8TC by braiding them the same way, internally they are very different products. The real 8TC will have a much higher grade copper, but if you strip the individual wires down, you'll notice that the individual strands of copper are all different sizes, and they are wound in a very specific way. The clone is just going to have off the shelf 20 gauge (or whatever gauge looks close to the Kimber), stranded cable. The point is, the clone may look the same, but they are very different products. If you are interested in this type of thing, someone just posted (I think it was Darko) a video of the process Cardas uses to terminate their cables. Its just amazing to see how much skilled labor goes into sticking a pair of RCA connectors on the end of a cable.

[@hoth2112]

@@AT-wl9yq Correct, it's way too-many strands in a small location. Likely why only 4-5 stands were ever connected on either end/leg, but it really defeats the benefits of a braided geomtry, cutting the effective gauge of the cable as well. That said, the Chinese clone cables also use a variety of sizes within each wire, much like the Kimber, but the purity and materials aren't as good. It's certainly not OCC and Likely using PVC or polyethylene instead of teflon like the kimber. I still need to watch Darko's Cardas video.

you did a really good review and like most things audio. there are subjective preferences. speaker designers as long as i have been alive have tried to maximize the inexpensive driver. i just have never personally heard one that really impresses me and i am familiar with that woofer. when you put the power down the problems always show up. my current favorite $1k bookshelf is the dynaudio emit 20. great drivers. basic crossover and reasonable box but the drivers deliver even when pushed to their physical limit

[@davidketley5359]

Can you measure the difference?

[@alanburnham9832]

Great job!

[@dmark2639]

I think it's about finding drivers that are predictable and perform in a way that is controllable and complementary to each other so that the crossover point is smooth and natural. Many times excessively overdesigned drivers use exotic cone materials like ceramic or magnesium, or other metals that may be stiff and pistonic, BUT ring like bells! Crossovers can only do so much to control such bad behavior, and it just adds complexity and additional expense to the overall design to control the "high tech" overbuilt drivers that may look better, weigh more, but also cost more too. These are not "cost no object" speakers...they are engineered to perform way above their price point when compared to other speakers. I hope Jay reviews them with that in mind.

[@pauldavies6037]
