I like that you could hear a difference, but not sure what your reference was.

What grounding scheme were you using prior to the QKore, and, I guess, which other grounding products were you comparing it to?

If none, then I would be wary of the conclusion, because that would become a comparison of grounding vs. not grounding, which all audiophiles know is a crucial sound issue.

If you ended up sending the product back and not keeping it, I would recommend a Google search for "start grounding," as I have found that to be a superlative grounding approach.

I enjoyed the show report, I saw this product was in use in their display room, I wonder what their ultimate ground "anchor" was way up in that high rise!

Cheers, Jason!

First paragraph: ... in a high-end system that, in my case, is fed by an 8-gauge dedicated line with its own copper ground rod driven into the terra infirma of the fault-ridden Pacific Northwest.

"low voltage attractor plate etc. etc."

I sure would raise an eyebrow.
It's meaningless pseudo scientific gibberish from beginning to end.

A suggestion: Connect your grounding rod via another 8 gauge wire to your main household water supply pipe with a metal strap. (It's standard practice here in the UK.) Then take your 'household ground' from one or the other, not both.

Pseudo science is rather popular among audiophiles. Don’t you know?

But I'm not new. I have been interested in high fidelity music reproduction since the 1960's. Nowadays I see so many 'useful idiots' in the hifi magazines advocating such garbage (and many people falling for it) that it is beginning to put me off the entire hifi 'environment'.

...you seem to be new on this site. I used to be bothered by audio flat-earthers when I started reading this magazine (and other audio related stuff). Now, I just laugh at all audio pseudo-science.

But only feel moved to comment when I see reports on nonsense such as this. (I'm a mathematician/physicist by trade, employed, but now semi-retired, in the 'big' computer industry in what you might call 'leading edge applied physics'.)

The pure unadulterated gibberish I see so often in the hifi industry and its dependents, such as the magazines, has, I feel, greatly damaged the credibility of the industry as a whole. EG: Where I live, Southampton UK, used to have about eight specialist hifi shops. Now it has only one, and that one is not doing well, despite that expensive hifi is not something people usually buy online.

Also of course the 'mass' manufacturers have come up so well that the tiny specialist manufacturers can offer very little in the way of better sound except possibly for speakers. It's not a matter of diminiahing returns, it's a matter of no returns at all from the high priced specialists, even more so when the price of all other electronic equipment is reducing while theirs goes up and up. It's not that people can't afford it, it's that they choose not to buy it.

How can you deny what Jason heard?

Side note: I am fine with changing 'pseudo-science' to a term that doesn't associate itself with science at all. How about we switch to 'audio mythos' or 'audio superstition' and get well clear of besmirching science at all.

But what he (or anyone else, including myself) think we hear and what sound is actually emitted are not necessarily the same.

As for your other comment, "pseudo-science" is fine. It underlines the total falsity of many of these claims. Here in the UK we have an 'Advertising Standards Authority' and some cable companies have been prevented from making such false claims.

Why, what could possibly go wrong with that?

The EU regulators who blocked amplifier outputs must have seen this insanity coming.

"...Connecting just a single power distributor or conditioner to a QKore1 or QKore6 brought marked improvements; adding as many additional components as possible increased the effect greatly. The law of diminishing returns does not apply; the differences were cumulative, and anything but subtle..."

A sure shoo-in for the next Nobel Prize for Economics, just a matter of showing empirically these thingies do indeed invalidate a fundamental tenet of economic theory!

It's physics too. This nonsense box from Nordhost, the recently announced 24,000 dollar loudspeaker cables from Audioquest, etc, etc, etc.

And there is no known science behind any of it.

THEREFORE I will only consider purchasing any of such stuff when the manufacturers show me their Nobel Prizes for physics. Until they can it all remains snake oil.

Waiting for the review of that $24,000 speaker cable by JVS :-) ...........

Bogolu Haranath's picture

If the loudspeaker is Quad wirable, the total cost for the speaker cable would be $100,000 :-) ..........

That would be the 'law of increasing returns' :-) ............

May be DSD 1024 and PCM 32/768 are examples of 'law of increasing returns' :-) ............

mrkaic's picture

The stuff is actually too cheap. It would sound so much better if it cost twice as much.

spacehound's picture

As I have said before, here and elsewhere, when these manufacturers show me their Nobel Prizes for discovering previously unknown physics I will start to believe there may be some truth in what they claim.

But there is another problem. I have never seen any physics equations with 'price' as a factor and I doubt I ever will.

Happy new year!

spacehound's picture

I have got fed up with all the nonsensical stuff reported on many Hi-Fi sites so mostly only comment when I feel really annoyed by all the garbage.

For what it's worth Stereophile is far better than most. There is one well-known site where the 'anti-science' (not just ignorance) has reached ludicrous levels and any semblance of objectivity appears to be actively discouraged by the site operator.

Happy new year to you.
