Todd, it is so easy to overdamp. I have 0 dampening material in my system..I have removed all dampening materials from the surface of my walls. With the correct materials and geometry either designed into the rack or in addition to the room itself you can bring the music closer to the real thing.I am an active proponent of direct coupling all equipment including the room boundaries. I am a dealer for a certain product line that is an original. A product line that takes some shots from the readers here..I personally have been using some of these products for 10 years. I did some experimenting with bags of lead shot..adding them one at a time to my system. At first I thought WOW what a difference, and there was a difference..I continued to add more dampening/mass...until I said my music has left the room..I reversed the process one at a time..The music started coming back,piece by piece..till finally the lead was gone but the music was back...You really need to check out the Audiopoints.com site. I am a dealer for them..but before you buy any point, bearing, rubber or fill material read their pages..Tom
