Longer Power Cords Sound better?

ROMEX? Out done again, rats!

Ie, if you hear a difference, by all means do it! Especially if it's a VH Audio DIY Flavor cord. I like Chris's stuff. I may just buy the components to make a 20 footer to see if I CAN hear a difference. But this time I'll use a hot pink jacket and shrink tubing.

Clearly, even in audio, size does matter.

Me, I would think about the room first before I start to think about power cord length. the room will more difference than any cable or IC now if the room is done OK or go spend money on music YMMV Marc

In a word; NO.
If your PC sounds better in a longer length, then you've got the 'wrong' pc. Of course, by wrong, I mean 'less than optimal', not 'horribly awful'.
I've listened to pc's in roughly .5awg increments between 9awg and 13awg, and in .5 ft increments between 3ft and 8ft (in gauges 10-12).
Yes, I'm that obsessive.
And when you find the 'right' gauge and length, that's when you discover just what your gear is capable of.

...13, 14???
