Best DIY tweak?

Hifisoundguy, I am interested in what you have written but not sure I understand exactly.

Are you basically saying to wrap the bottom portion of the center RG6 cable with Teflon tape and push the tape down tight where it touches the Connector barrel ?

Can you send me a picture ?

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

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.

Using the Ultra Bit Platinum liquid on your CD's.
Doesnt seem like it should make as much difference as it does.

I have made many compliations of my favorite artists. Ultra bitting the CD to copy from and the CDR (usually a Mam-Audio Master Gold CDR's) to be copied to.
The copy comes out much better than the original.With better soundstage, treble, midrange, bass.

I also will add that after buffing the heck out of the CD's, I then use my Bedini Clarifier on the CD's to prevent static build up before I copy them.
