Cheap tweaks...What would YOU reccomend?

Upgrade your fuses!
This may have been mentioned before in this copious thread. I cannot emphasize and recommend the difference this simple, relatively inexpensive tweak can make highly enough!
If your system is HARSH this will make it smooth, if you desire more definition this will improve it. If you desire greater clarity, cohesiveness and bass control these can help.
I have upgraded the fuses in every piece of equipment own an have yet to hear a definite improvement.

Upgrade you wall outlets to Maestro! I have Porter Ports before, and they were a terrific bang for the buck, but the Maestro were equivalent to a component upgrade, with just one installed on my wall outlet that the power conditioner is plugged into.

Yes Bullot, the Maestro ac outlets are an AMAZING BARGAIN....Price vs Performance !... You can read my review here... http://forum.audiogon.com/cgi-bin/fr.pl?raccs&1280581691

Make sure the CD is absolutely level while it is spinning.

DAKIOM feedback stabilizers which control vibration electronically is the BEST tweaks you can have and I have 30 plus years of tweaking experience and a former high end home theater installer and electronic tech. I have used dbx, omnisonic imagers, hughes, srslabs,bbe, behringer, carver sonic holography, peavey, aphex and many other sound processors, dakiom stablizers coupled with any of these sound processors including acoustic research tds 202 is the cheapest and most effective tweaks in cleaning and expanding the soundstage of a system. Tube rolling is also helpful in solid state. Cables makes very little improvement unless your gear is that high up in the food chain. For the most part, most cables are just for aesthetics
