RainEX as CD treatment.

Using furniture spray on the label side of compact discs(preferably Pronto from Johnson's), because of the static inhibiton inherent in the spray. It makes for tighter bass, deeper soundstage, more analogous sound.

Speaker Cables! No one ever believes it, myself included, until you do an AB comparison. I change the 24 GA zip cord in every cheap stereo I can find to the cheapest Kimber model (4PR) and it's like you just tripled the price of your system.

Used two pieces of fine-grade marble slabs to make a Kevlar sandwich back in the '80s as a platform for my Thorens 'table. What a difference I noticed in terms of damping resonance! Sorry I didn't market the idea before Bright Star's inception.

At least a 24 hour warm-up before listening.

Pc sound card: upgraded the sound quality on a regular 6-channel card by 'modding' it: 1) added a voltage regulator 2) beefed up the decoupling caps 3) wrote a new windows fm801 driver (without a word of a lie, this actually made a huge difference)

A top notch audio rack; then rid your system of all that junk that everyone puts under their equipment.

sorbathane under the cd player and under the sand boxes the speakers sit on. (upper floor listening room).

Lot's of beers for Rock and Roll. Bottles of wine for Jazz. Kaopectate for New Age.

I've been using the thin green perforated rubber pads that are sold for refrigerator drawers between spearks and stands. I think it provides damping and slide-resistance similar to Blu-Tack and allows for easier fine-tuning of speaker position on stand. Costs a buck.

Instead of the really pricy CD mats, I took apart an old 5.25 inch computer disquette. I run it on the demagnitiser along with the Cd and insert everything in the Cd tray. Great sound and really cheap

cables, i now believe

not a tweak, per se, but i recently shipped my Classe power amp back to the factory for servicing (right channel was cutting out on me at unpredictable times, not reproducable on demand, but frequent in occurrence). they had it on their test bench for 2 weeks, at which point they said they couldn't reproduce the problem. they shipped it back to me, without doing anything to it at all. after reconnecting it into my system, is has performed flawlessly -- the channel drop out is gone! strange!

OK, you asked for it. Here it is. Brillianize! For cleaning records, no kidding. I know Mikey
