In my experience different pieces of gear react to different thing.. I found the better the power supply, no mater what they are suppling react LESS to high dollar power cables. If there is a huge gain in performance because of a PC change, I'd look more at the power supply other than the cable. I wholeheartedly believe that because I've proved to myself..
An old Mcintosh MC275 doesn't know a piece of lamp cable from a Krell PC. WHY? Look at the power supply..
Their BRAND new stuff ALL has room for either Mac or aftermarket PC.
WHY... thing are a changing even MAC has much better cabling NOW.. Sure took long enough..
I could see a Mac fuse.. I wonder what they would price one at.. Macs aftermarket cabling is pretty reasonable.
But even I have to look at what we're getting when we buy a Mac NOW.. I'm looking for my LAST preamp/power supply C100/1000/2000 series..
I think ALL tweaks, and even cables are a back burner issue.
Plug it all in, clean up the mess and Prepare the room FIRST.
Speaker placement in a treated room goes a long ways to ELIMINATE future tweaks (which are patches in disguise). A real tweak is something like a real good contact enhancer... It works no matter who you are or what it's used on. 5 people will hear a difference in 5 different systems..
BUT someone that's using cabling to modify the way something sounds... NO! I want it to reveal what's there, not HIDE, CHANGE, or exaggerate it.. REVEAL, UNMASK, SHOW ME, the beef!!!!
