Twl I am not getting any feedback at all even in high listening levels, so if I read between the lines you feel this would add no value to the dynamics. The reason I am thinking about this is I have a salamander synergy 40 w/ 30 extention for amp pre amp and source equ. TNT sits on a salamander synergy tv-30 looks just like the other but has a huge top, I just thought a little more weight may help dampen it a little better Thanks for all imput on this issue. David
