How can power cords make a difference?

Hi JHunter,

I now have three NBS Statement power cords, two on my bi-amps (Aloia) and one on my SACD
(SCD-1) player. I have BMI Whales on the pre-amp and suppling my PS300 conditioner.

I have actually done a lot of testing with power cords with these same guys over the years. We have had sessions where they or I are blindfolded and we will try two, maybe three cords. The trick of not switching is a good one to see them squirm, but I've found it meaningless. My experience is it's almost 50/50 as weather they heard anything. I've tried to inject the no switch test a few times in one night and all that happens is confusion from the listener, and then they begin to doubt everything they hear. I'd say my experience with that trick is it may actually be counter productive and invalidates earlier findings.
This blind testing has become a game for us, it's fun to see how well we pick up on subtle changes.
It's not ABX, but I insist the results are as good or better. I have two amps, exactly the same model. We've played with switching between amps with exactly the same interconnect model, of exactly the same age. We have found one of the amps to be a bit better in it's high range than the other (guess which amp is wired to the bass and which to the midrange tweeters). I suppose it could be burn in because they were bought at different times, of it could be shelf placement, or one having cleaner terminals, I happen to believe nothing man made is exact, and two identical pieces are never identical. This is why I believe my testing methods as described many times here on these threads provide more valid results than the clinical approach demanded by some here. It's funny that the demands keep coming for tests, but there are no attempts at real tests by these guys, and a flat un-acceptance of the results reported by so many here on Audiogon. I guess again I'm proven too stupid to understand there higher life form. Happy testing, oh ah listening, no enjoying the music, wasn't that the purpose?

While not cable related, an an anecdotal exchange occurred this past weekend that gives an interesting bit of insight into how some people's training is almost akin to brainwashing.

A couple of friends helped move my large items like furniture to a new place. My system had been moved and set up a week ago, though it is still going through fine tuning for the room.

Both of these friends are mechanical engineers. Rex is a vibration control expert who's into home theatre. We've had many a lengthy, often times spirited, exchange on equipment. Rex is, for the most part, a non-believer in tweaks and cables (after a point). This was the first time he's heard my system. John, as I've described before, is an acomplished musician and has spent many an hour in my living room listening to music. He knows my system almost as well as me.

The work finished we settled in for a couple of beers and a demo for Rex' benefit. Unrelated, but I found it interesting that Rex, Mr. HT, found it necessary to drive the volume far beyond what the room would handle. Not just as a test of its limits, but as a chosen listening level. He did exhibit a good ear by pointing out a shifting image in the soundstage I hadn't found yet.

Anyway, at one point Rex picked up a spare set of Black Diamond Racing cones that were lying next to the rack. The gist of the commentary was that all tweaks are "snake oil", that nothing in his training allowed that they could possibly do anything to effect the production of sound. He and John kidded about going into business making something that *seemed* exotic and how well it would sell. Then I made a mistake. I reminded John about an experiment we'd done with the BDR cones. One afternoon we had put a spare pair under the pre- and, he admitted, then and in this conversation, that it *had* changed the sound. He blubbered some excuse to Rex about not being able to quantify whether it was an improvement (his otherwise good memory suddenly failing him) and the subject was quickly changed.

While helping me return the moving van John took an opportunity to mildly chastise me for embarrassing him in front of another professional engineer. He was obviously torn between his education and that of a respected colleague's and first hand experience.

It's at times like this that the fact I am, for the most part, self educated, has great value. It has not been drilled into my head that "this is *always* the case" and the ability to see things for what they *really* are is still part of my faculties. It's unfortunate that education somehow has taught these otherwise intelligent people to believe books before their own senses. That's not to say education is bad, just that the rigid thinking it promotes is one of its downsides.

BTW, I know deep down John is actually a convert as he's been around while my system has matured. He's seen what various cables and tweaks have done, both good and bad. Rex doesn't know it, but he's next.

Redkiwi: Your last post shows we're somewhat in agreement. I would gladly participate in an exchange with the members in question if it were an open minded exchange. I simply refuse to participate in circular debate. It serves no purpose except to occupy space and time. That and it frustrate me. Apparently you, too, after awhile.

Albert, Jadem6 -

OK, I'll bite. Could you two get together and figure out, say, 2 cords the most likely to differ from stock? I'm willing to listen to them, first sighted and then blind, and will report back the results (and return the PCs, maybe . . .). Might have a chance to pick up a PC from Bruce, but would like to keep the total to a reasonable number.

Cheers,
Jhunter

Jhunter. I just spoke to Jim Aud of Purist Audio Design. Jim has graciously offered the (temporary) loan of a Dominus Power cord for your testing. If you will contact me via the Audiogon e-mail system, and give me your physical address, the cable will be sent directly to you freight prepaid.

I will most likely get my Acrotec cables back this next Tuesday, and I will ship them separately.

this is *great*!!! i *love* it!!! now, all we need is for 702 & stevemj to agree to try 'em...
