Where to put damping sheets?

what kind of adverse affect can putting too much damping have?

On the matress?

The adverse effect is that the music loses it's dynamics and lifelike sound ( duller or darker ).

Mburnstein that's a dumb answer. You don't want damp sheet on the mattress, they need to go in the dryer!

What results did you experience with the places you applied the sheets, and how did the placement relate to the power supplies?

after putting the damping where i did, things seemed a little more focused. although i didn't do real extensive listening, cause shortly after that i changed the op-amps from the 2604's to the dual 627's. now that did a lot. stretched things out, gave it better depth, and detail, but very smooth.

i'm not saying you're wrong but if the purpose of the damping is to reduce vibration, and you put so much you remove ever vibration in the player, woudlnt' that result in the most accurate playback? how can you overkill on removing vibration?
