Entreq Tellus grounding

[Orb]

Ok I give in and yeah I never worked engineering from day of the Modems through to modern day DWDM/WLAN/3G/etc and the various IC for those transmissions in each era and the hardware that connected to these via various interfaces and cables (including all aspects of PBX old and modern digital)... Sarcasm just in case you were wondering.
Thanks for simplifying it for me Kevin (although you miss the context and point to fit your argument) and lets leave it at that, for god sake please stop pushing Jim Brown (yes I know about him) and mostly the focus on HAM, other engineers have had to work with signals and mains.

Edit:
Reading your comments again, it really does not answer anything I raised several times in the right context, in fact in many instances you go to a very different tangent to what I was discussing.
Again I was differentiating between mains and signal related issues especially with unbalanced RCA, the reason is because I have always said we needed multiple solutions that compliment each other (it is too late to do anything with the actual audio system components as designed and implemented by the manufacturers, which much of what Brown and others work would relate to putting aside the mains side)
TBH is to be honest.
You say olden times interference was very different to now in reference to I assume my background because I mentioned the sensitivity of communications equipment historically and yet you keep presenting papers from 80s relating to signal-noise-ground (that would also need to consider interference and multiple system connectivity).

That is interesting, as far as I am aware no one has ever been able to tell the difference between an after market power cord and a kettle lead, in an unsighted comparison.Does that mirror your experience?
Keith.

Interesting statement. You might want to get out more. Maybe read some reviews from virtually every country in the world. Check out some of the professional recording studios that use our products, like Astoria, that just happens to be in your neighborhood. Check in with the many audio manufacturers that use our products in their research labs and listening studios and at audio shows. Many of these companies also use our power and signal wiring within their products. Perhaps read some of the feedback from thousands of customers.

So I have question for you. Have ALL of the products you sell been ABX/DBT tested and certified by an independent association or organization?

Interestingly, that is how i discovered power cords in the first place. I had not been aware at all of after market cords that cost serious money. I walked into my local store, heard a system of good quality midfi for about 30 seconds...and was absolutely shocked at the solidity of the notes, the weight of the presentation. After about 30 seconds, i realized...duh!...must be an audiophile CD.

...changed it to MTV Unplugged which i use all the time...solidity and profound silence/background still there. I went out and interrupted the Manager and i said 'no way that system should sound that good...what did you do?' He was dumbfounded and said nothing special. i went back in...and after 5 minutes, came back out again and actually asked him to come into the room and listen.

After 15 minutes of going component by component, i spied some big black cord thing and asked...what the heck is that?

...Purist Audio Dominus Rev B power cable.

...i took it home to audition and bought it later that week.

For me, the ultimate blind test. i discovered a new sound in a system i was reasonably confident i knew, and had no idea why...the manager said there was no change...and i had to go back in again and re-verified to myself NO WAY...and after 20 minutes, we both discovered i was hearing the benefit of the PAD Dominus PC which i liked and still like to this day. That was 7 years ago. I still have that cable and with the same component.

This is hilarious. This last few days have been full of posts outdoing each other, here and on Peter B's thread.

 

[Barry2013]

You seem to assume much and know very little. I am an advocate of blind tests, sighted tests and scientific measurements. But keep digging the hole.

Keith is good at digging holes. There are many cemeteries looking for this skill.

Keith.

I have never heard two power cords that sounded alike. Presumably, your experience is the opposite. In some ways I envy you and in others I'm sorry for you.

The envy is more money saved using the OEM cord, the sorry is not hearing said components to their fullest potential...

I well remember when ARC component had attached power cords, and I am sorry that I had to use them for years. Once I cut off the attached pc and used a IEC pair and my own pc. Also once I cut a hold in the chassis and shaped it to take an IEC chassis mount.

Guys,
I notice your selecting Keith/Purite Audio for his stance but he is not the only one in this thread with views on power cables, Speedskater goes even further:

It only works as an interference antenna when there is nearby interference. But sometimes audiophiles prefer signals with a little bit of background noise or interference, it seems to add definition or sparkle.
.....
Not a rationalization, when real differences are heard between cables, my first thought is background noise or interference. An audiophile's preference may not be for the quieter cable.

Cheers

Well if anyone can point to an unsighted test where a listener has consistently selected the after market cable, or if one of the manufacturers here can provide some measurements that would explain the perceived differences?
Keith.

Hi Keith, Yes, me using my Wife, which is far from being fan of this hobby.
I replaced stock PC cable with Elrod Gold PC, without telling her to be concentrated on how improved the sound was with the ELROD PC.
She didn't ask me measurement to prove it.

 

[JackD201]

..... if one of the manufacturers here can provide some measurements that would explain the perceived differences?
Keith.

Would you even believe it if it were presented to you?

 

[Orb]

Some measurements even from manufacturers would be a start, power cables, grounding boxes , let's see them.
Keith.

What measurements have you taken when improving the house earth and house mains using Triton/transformers/separate spur-ring/etc
Funny enough my own experience, the original earth-bonding to pipe was pretty mediocre and not done to best standards, changing this improved the perceived noise floor of my equipment-music played for the better but I doubt the measurements you would consider would prove that should happen; even the electrician (yes building regs/P certified) was dubious until he heard the difference (and this was easier objectively to identify as a perceived trait).

[Orb]

That said Keith,
Speedskater is suggesting that Entreq is actually adding noise or interference (in fact applies this to cables in general it seems and aligns in many ways with your own POV), so you should be able to measure the negative effect quite easily

SO get one on a 30-day money back (think that is available) and measure it.

[Orb]

Some traits go beyond anecdotal Keith.
Noise floor and noise with music or specific sounds is very easy to check don't you think if done carefully with listening?
Same can be said about distortion, this is not general casual listening to whole tracks and albums but focusing in specific trait at specific sounds-points in a track.

But are you debating my point about the house improvement earth or more generalise listening for noise, or even the subjective improvement listeners mention with Entreq and also slightly off-topic cables?
Anyway why not purchase their basic model on 30day back guarantee and measure it-system output for noise and interference ala Speedskater (his views seem to fit with yours) mentions is happening to cause a difference.

Seems you are throwing up arguments against for the sake of it now.
And you neatly side stepped my question to you as well on measurements and the fact it would not necessarily show what your looking for with my own experience of earth-grounding or possibly some aspects of Triton and other solutions

Orb

At least he has been consistent in throwing up the same argument across forums, across threads, for many years.

I can understand why, looking at what kind of speakers uses to make its test.

 

[Orb]

So Peter Walker is fine Keith but any other engineers from other manufacturers are not?
Not sure what you feel raising Peter Walker actually adds to this *shrug* when you will not accept other engineers in audio companies (and before you respond I am not talking about the "designer" at Entreq who I feel has problems communicating his product's effects technically IMO but more traditional mains and hifi companies).
I assume you would say Naim and MSB Tech then must be doing a con with their additional-improved external PSU and even cables with Naim, because surely their products should be built to highest spec for mains-input stage-etc.
Ah, but then Weiss also offers the external PSU101, and Chiron cables; Yes I appreciate you sell Weiss and their extra PSU-cables
Its a smile because I cannot see how these sit with the position you take in this thread, and critically when you present Peter Walker.

Why would anyone bother? I still want to know if all your equipment was bought as a result of DBTs.

 

[caliaripaolo]

You aren't comparing Peter Walker to the 'cat litter' boxes are you, or to the rebuilding of commercial cable in fancy sheathing, because they are not in my opinion engineers.

I like the part of the interview where Peter is asked whether they listen to their amplifiers.
Keith.

Hi keith,
I do not want open again the debate or argue about "cat litter" or "plastic trumpets" but I want to ask you a simple question. Each has its own opinions and I respect your
Please, respond yes or not only:
Do you think some sort of "Stray Voltage" and/or “magnetic fields” have any influence on sound quality?
