Chord GroundAray Review

This is a strange type of entertainment, but it grows on me more and more every time. Thank you!

The special material inside that dissipates the noise though quantum tunneling to a parallel universe is AKA snake oil. Another wonderful debunking video Amir for a set of devices that's not cheap either. Thanks for making a YT video review as I suggested.

[@mysock351C]

Shamelessly preying on people's ignorance. Analog filter on an ethernet network using balanced differential digital signals. If its noisy enough to cause issues, you just don't have any audio at all. It simply drops the data packets.

@Douglas Blake I would consider it’s intended application to be as such in principal for the sake of argument. In this case it would be equivalent to an open stub of coax. But given there is no control over the dielectric properties or dimensions, not to mention the housing is likely floating, it probably couples and passes a very tiny amount of HF RF components through the RJ-45 connector rather than where they claim it goes, which is magically dissipating in the wire inside. Never the less, even if it did have actual passive or active circuitry inside and it did present a low impedance to noise, it would still be useless even if it did quiet things down. The digital signal is differential and by design rejects noise.

My very first experience as an audiophile started in a local audio shop in my area. They had amongst other things these noise filters, a plug attached to a cylinder. They said it removes electrical noise from the outlets, improving clarity and sound fidelity. I knew something was already off, and this item you reviewed is certainly the same thing revisited. Glad to have you on our side. Keep it up.

[@cornerliston]

A psychiatrists explained to me once in a very easy way how our cognitive works: Say you're walking in the streets and you notice there's a lot of different cars from many different manufacturers. The focus is ‘there's a lot of different cars.’ Later you decide you are going to buy a car. You decided on a specific car or maybe a specific colour of that car. Now walking the streets your focus will instead be set on that very model or colour, making you think that this car or colour is specifically popular. While in fact nothing has change other than your cognitive.

I wonder if Danny at GR research has an upgrade kit for it. What makes me mad is not the existence of these. Its the fact people have the disposable income to buy this trash vs donate it to an animal shelter or non profit.

[@cityoflights3808]

Don’t give Danny any ideas…I can just see him offering a kit with “upgraded” “audio class” capacitors and resistors and wire connectors that costs more than the unit itself and requires rebuilding the entire pcb board. Like many of the speaker upgrade kits inexpensive or ancient speakers that cost much more than the speaker itself, sometimes speakers that are fine to amazing for their price point to begin with (Andrew jones pioneer and jbl 530 for example). Why people buy such things instead of just getting a different speaker boggles my mind. I have pair of cheap to begin with and now very old Mordaunt short ms30i with cheap as chips first order crossover and a bit of beaming as a result, but also pretty spectacular high e d imaging and sweet midrange on vocals. After all the woofer and tweeter were both designed to work well with a first order and the cabinet, As an experiment , I tried a few order crossovers at different crossover points (diy, decent parts) and guess what, the beaming was gone but so was the all the character of the speaker. Yes I have “better” measuring speakers, but what’s the point of having vintage and vintage-y stuff unless you enjoy them as they were designed. An old MG can be fun, no need to try and make it a Miata or Ferrari. If I want to listen to precise studio monitors or other better measuring speakers I have those too. …though I do have a pair of mirage MRm-1 that I would love a bit more if their center imaging weren’t so fuzzy (these are not omnipolat or bipolar types).

Thank you for another informative myth busting video. I have a q, hope someone can help. The room with my audio gear has no grounded power outlets. On the rca inputs on the amp i can feel the electricity running when lightly touching (small vibrations). After plugging in rca in amp to 3.5mm audio plug into laptop it seems less/gone. Is the laptop grounding the amp or am i placeboing myself? For proper grounding would it work to connect a wire from one of the rca inputs on the amp to the grounding metal on a grounded power outlet in a different room? So like using a modified grounded power plug with just the grounding wire used, terminating into rca on other end.

[@AudioScienceReview]

It is "normal" to have that kind of leakage current, i.e. enough to give you a buzz. It is safe from electricity point of view but can cause ground loops.

[@mfr58]

You need a competent electrician to assess your wiring. Ungrounded equipment, designed as such, class 2 or double insulated, can float at elevated potentials, often half the line voltage. Whether it is healthy to have a computer sitting on your lap with such fields present for prolonged lengths of time is open to to question.....

If you take that wav file and boost gain by 105db you can hear those differences. The differences are muddled by the noise floor, but technically there is a difference. Is it possible to do that null test between an r2r dack and a delta sigma dac?

[@AudioScienceReview]

As I explained, that difference is there even if i don't change anything. It is hard to get perfect sync due to variable clocks. As to R2R dac test, yes, that would be good to run this against. Currently I don't have one to test but when I get one, will run the null test.

After this most recent round of reviews of “tweaks”, resamplers, power cords, cables and conditioners (plus other science based testing by Amir and others) , one can be pretty confident in the general inference that such products are worthless at best, and often make things worse. In fact what are great about Amir’s reviews of these items is he explains the failure of these products through scientific principles such that the results are applicable to the entire “class” or type of products (ie, not this expensive power cord but every power cord) and cannot be ascribed to be particular product or even one item or set up. Either the designers do not understand basic principles of electrical physics and acoustics, or they make engineering mistakes that are simply unacceptable at any price (see the Chord resampler) or they are cynically dishonest.

To the point of focusing on the music when evaluating something, I've noticed this even when testing cheap audio gear after a repair or speaker swap. I'm amazed how good that cheap thing sounds! Then I get used to it and realize it's not that special.

[@GMG0479]

Not saying it works or not, but at least the intention of use is to connect it to an unused connection on the streamer or DAC, not to a spare port on the network switch. Rj45 are isolated so maybe it doesn’t make sense. But RCA connections on a DAC share a ground, so maybe this thing has a chance if it is connected to 1 unused RCA while music is played through another set of RCAs. Probably not, but just though it makes sense to point out the usage

And decide to change their views. Indeed this is why I continue to get products like this to test. Also, prior to purchasing these things, people perform searches and land on "reviews" that are basically informercials. They see all positive messages and think that is the consensus. It is important that in these searches, the counter point is also shown on equal footing, i.e. video. Finally, opinions are changing in audio. Every day more and more people put value on proof points about audio claims. That is happening because of continued testing like this where there is hard proof and not just an opinion that they don't work.

Personally for music, if I already have that much bass response, I would not bother with a sub. If you want to add one, then must measure the room response and get it to be even in bass. Otherwise you can have very boomy bass.

[@johnsmith1474]

@@AudioScienceReview - Does the sub drive the passive to any meaningful degree? Thanks!

[@johnsmith1474]

@Douglas Blake - "It can ... depending" is no more information than exists and is implied in my question, so thanks but that's unhelpful. I understand physics quite well (why I asked). The essence of my question is however, "... to any meaningful degree" ie "... in practical application." A boat may be leaky, but if it's inconsequentially small and you have the means to deal with an increase then sail on. To turn it around: there are a lot of well known best practices the hifi hobby but I've never seen a statement about subs used with passive radiators such as "Don't bother, it sucks." A 15" Klipsch sub goes far lower than the Forte II so the idea is enticing, but it may be impossible to achieve without muddiness across their low end overlap areas because the passive is so easily resonant, whereas a sealed box would have far less of an issue.

[@JJSDesignPL]

Reputation of Chord company went down to zero after your recent episodes... what a shame for them. Do you think they feel ashamed selling something like this for almost $800?

[@AudioScienceReview]

As I noted and strangely so, this is another Chord company than the one that makes DACs. This is called "Chord Company" and the other, "Chord Electronics."

[@jimfarrell4635]

It's interesting to note that Chord Co. have recently revived an old brand, English Electric. Their first product is *sigh* an "Audiophile" network switch. Sounds like from being a decent cable company they are taking a dive down the rabbit hole. It's a shame, as I said below, they do make sensibly priced, well constructed cables.

MoFI should use this to cut their digital vinyl #mofigate , A company makes vinyl from digital files, sells as pure analog "from the original source" , no audiophool finds out for decades. (the same people claiming to hear jitter and cables )

Good suggestion. :)

[@xprcloud]

@Douglas Blake Did it ever occur to you the snake oil of using vinyl as an effect machine? adding wow flutter , EQ and dynamic compression, mechanical, distortion and lots of noise to a digital perfect 1st generation recording? turning it into a 3rd generation degraded "analog" artifact, and a bunch of audio phools applaud as we poke a finger in the eye of Hi-Fi science and any engineer that ever developed a better way of reproducing music, Also forget about boasting the longevity of viny, and analog tape digital perfect copies live in multiple regional cloud data centers across the globe, and within each center, multiple copies, on enterprise class storage systems, and within each region, additional data centers physically separated from one another, hold additional copies , and accessible from your device in microseconds from any place on the planet well excluding NKorea ....VS a decaying vinyl that sounds "different" every time you play it

[@hoobsgroove]

aren't you just missing the point in what you said about low noise floor, it's designed with people who have very noisy systems not a quiet system like yours. that's the purpose of it the ones I've ever seen have a earthing terminal on them that doesn't???

[@MichaelBeeny]

Someone thinks it works!!

[@AudioScienceReview]

How is my system quiet and yours noisy? This is a computer workstation with tons of activity. Its ground is surely polluted as I see with poorly design DACs and such. But sure, let's have the company run the same tests on a system -- any system -- of their choosing that shows a difference.

[@olasv097]

Why do you so often make reviews of these “junk products”? Why not focus on normal products instead. No matter how many of these review you make very few will stop buy these products. Your fan base would never buy these products in the first place. No offense.

[@olasv097]

@Douglas Blake, no, not really. I would however personally never buy these kind of products. I think these kind of reviews are counter productive. I get a feeling they are made for pure entertainment for the already “enlightened” ones. It just enhances to polarization imho.

[@olasv097]

@Douglas Blake, I’m an engineer, dealing with high frequency signal transmission and processing on a daily basis, I kind of have a clue what could work and not. There is a lot of snake oil out there. My point was that it would be nice to see a focus on good stuff instead of the bad stuff.

[@AudioScienceReview]

My "fan base" are the ones that are sending these products in for testing. Many have doubts and once they see the analysis, change their opinion and realize they were just following the crowd. For sure there is an impact. Not on the hardcore, head in the sane people, but the rest which is quite large population sadly.

[@alexanderfleming9104]

I see you have many reviews, but your results are all based on your mega-expensive analyzer, and interestingly... YOU NEVER DISAGREE WITH YOUR ANALYZER. From my perspective, your analyzer is the reviewer, and you are just an AUTOMATON, is that right? Your analyzer is YOUR GOD, and you are the Mesurements Jesus for the masses... Is that right?

[@AudioScienceReview]

Are you a real person or just an automation? I ask because the review starts with listening tests and that is the core of it. Null test shows conclusively that this device made no difference -- to my ears or anyone else's. Next time please watch the review before commenting. Would save time for you and me.
