Maybe the shielded cables happen to have lots of capacitance and are acting like a bit of a filter for noise in addition to the RFI benefits of the shield? Just a wild guess really. When I get my wooferTester, I am planning on measuring as much as I can with those.I was really surprised that a power cord actually had an effect. I stumbled upon it by accident. I mistakenly used a cheap PC cable and the magic really went away. The next day I put the original cable in just for kicks and the magic was back. I did multiple double blind tests with folks and they all said the same thing without knowing what I was changing.

Bill:You don't need 'fancy' OR 'expensive' to use the right gauge of cable with any component!
Even prosound guys will tell you - if you starve a big amp for current using too small of a supply cord, or the wrong sized branch circuit, then the amps bass performance goes out the window.
Cable gauge after the amp is equally (if not moreso) important because now you're driving even MORE current (at a lower voltage of course).
Now, if a cable that costs $1000 sounds better for use with a subwoofer, is it because it's a superior design? Or just because it has larger conductors?
6 feet of #8 or #10 SOWA or SOOW service cord (cab-tire) with 2 cord ends does NOT cost $1000.
Then again, if you're a REAL audiophile and you don't spend $1000 on an AC cord you just might not hear a difference!
Mine cost me $7 apiece and they sound great. :) Simple shielded 14g Volex.
