Cheap tweaks...What would YOU reccomend?

Do you have any particular brand preference for the antistatic spray?Thks

The best and cheapest tweak you can do is speaker placement. Experiment with moving your speakers away from the back and side wall. Aiming them to face in front of you or behind you. If you have floor standing speakers lifting them off the floor a few inches can make a considerable difference.

Mod Squad "Soft Shoes" under my DVD/CD player. For less than $50 I got what sounds like a component upgrade.

I accidentally found this on my decent preamp, I was trying to use 2 "Y" connectors from my CD player to connect 1 set of interconnects to preamp "TAPE", second set to a HT receiver, but instead I hooked it into preamp "AUX1".
(I was in the process of doing it and got interrupted with something else for couple days).

When turn on preamp with BOTH "TAPE" AND "AUX1" on, the sound is .. drasmatically changed, with unbelievable detail, image, even loudness.

Just about to post as question if this is a mistake, but I enjoy it so much that I decide to keep it this way, maybe until something ... explode !

I've been very impressed with those ultralight Neuance shelves under my CDPs (made a HUGE difference under the Rotel, and a more subtle improvement in coherence with my 44lb EMC-1 MkII). Far greater bass articulation and PRAT than inner tubes.
Also, the LAST thing you want to put under your speakers is an air cushion! Spikes, rollerblocks, THIN sorbo between
satellite/base sections are all great, but the object is to optimize the coupling to the floor...not isolate it (as you would do with other components...especially front end ones).
Have fun! Ern
