Cheap tweaks...What would YOU reccomend?

Turn off refrigerator! The improvement will melt you away!
(And your ice cream...)

I think I may have heard of this one long ago, but a gentleman pulled it on me last night and damned if it didn't work! When playing a CD, put the player or transport on pause for a few seconds before you start playing it (or if you want to see if you can hear the effect, do it while it's playing). Don't know why, but focus of the images improved noticably, usually after the first try, sometimes it took two pauses. Go figure!

Here's a very cheap tweak; it cost me nothing!

After posting a write up of my 2-channel only system on Audiogon, which included pictures of the room, a couple of readers suggested removing the television from between the speakers. It's now in a different room altogether. The result was improved clarity, a touch more air and a major reduction in a sibilance problem I've been chasing interminably.

Another cheapie tweak is to buy a small bubble level and use it on everything. Source components, shelves, speakers, etc. Leveling the CD transport made the most noticeable difference. The sound became more relaxed and had less hash and grain. The change was enough that now everything except the cables have been leveled. I tried to get them straight, but no matter what I did they drooped...

Fpeel, I understand there's a new product called Hardwire to be marketed by Pfizer. You apply it to your cable(s) one hour before each performance, and it lasts the whole night!
Cheers.

3 or 4 DH Squares under the TV/monitor produces noticeable improvement in picture quality - a more stable image and better definition.
