I have tried a number of different power cables (some with astronomical pricetags) in my $25K system, which has sound to die for (Vandersteen, Audio Research, OPPO, Musical Fidelity).

They don't change the sound of the system one tiny bit compared to using the stock power cords supplied by OPPO, Audio research, and Musical Fidelity. If I can't hear the difference in my high-resolution system, I find it rather unlikely that there is any difference to be heard.

As far as I have been able to determine, the hype regarding premium power cords is a lot of horse patooties heated by a lot of hot air.

Furthermore, as an electrical engineer I find the idea of putting a different power cord in front of a well-designed power supply circuit to be something that cannot possibly make any difference. If the power supply is well-designed, which is almost invariably the case in any decent piece of electronic gear, it is more than capable of supplying absolutely pure DC power regardless of the power cord.

To believe that a different power cord is going to make a difference, I fear that one must be extremely ignorant of the engineering principles involved.

Any circuit which is already supplied by the correct DC voltage is not going to perform any better by changing a power cord.

The whole thing reminds me of the amazing secret carburetor that would double an engine's horsepower while increasing its gas mileage (and don't forget the Tice Clock...).

Of course there are any number of perfectly good reasons why audiophiles sometimes don't hear changes in power cords or interconnects or anything for that matter, even the Tice Clock. Stereophile Magazine, perhaps ironically ran George Tice's letter to a disgruntled customer explaining the facts of life in the fast lane, and the reasons why audiophiles sometimes don't hear certain tweaks.

I liked these products so much that I'm trying out a prototype Maestro power strip that wont be on the market until later on this year sometime.

The noise floor is PITCH BLACK...the silence is AMAZING!! I've only had it for two weeks, I'll give a full review later on when they come on the market.

Silence?

Try turning the power switch on first.

Thanks! for sharing.
