Best DIY tweak?

I'm SHOCKED!!! nobody has tried my teflon tape tweak.... A good place to start is on all three prongs of your AC plug on your power conditioner...try it and your see what I'm talking about...........

Hifisoundguy,
I tried your tweak with my RF cable to my cable box .
Sorry, no change, no improvement.

Ozzy...Did you use PTFE teflon tape from Wal-Mart? You need to try it on all your AC plugs too.....

"Best Tweak" Just sit and listen. Costs nothing and you might find your system sounds good.

Maple Butcher Block Cutting Boards used as Amp Stands.

I was able to buy a 18 X 18 x 3 1 1/2" thick Maple cutting board.
I painted it Black and placed it under my Amp.
The footers used on the Amp are the Finite Elemete Cerapucs.

Anyway, the Maple wood does change the sound ever so slightly from when I was using a Granite slab under the Amp.
The sound is little mellower and fuller sounding, not a night and day change, very suttle but good pleasing change.
