granite base for speakers


Gentlemen- I'm using a trio of Vibrapods w/my Silverline Sonatinas on low-pile carpet. While everything sounds great, I'm the insatiable type- I'm an audiophile! -so once again, I'm experimenting with stone speaker platforms. I've got some 4" (thick) granite slabs that I put under my speakers, using the Vibrapods to decouple. What is your take on stone speaker bases? Is this this too drastic of a change in height? I beliefly listened and heard this; imaging was much improved, palpability was very much improved, strike that it was more like believeability was much better. Bass response was diminished and midrange appeared to be a bit harder than before. Problem is that I'm right in the middle of burning-in (2) Shunyata Viper v2 power cords, so everything is in flux. I realize I'll have to wait till the cords have settled-in abd a/b the granite but just wanted some opinion on my query. Thanks guys. Mike mwalsdor@cscc.edu

I use concrete blocks as a base for my Dunlavy speakers (the blocks are painted for WAF). This raised the speakers 7" -8" off the ground and so I had to raise the sofa to match the height difference. ( with concrete blocks also, not appreciated by the wife, who nonetheless has stopped complaining about it). The results are remarkable. Dampening is excellent, dynamics are improved. Overall an excellent tweak at an extremely modest cost. But it is important that your listening place (sofa, etc) is also increased by the same height as the speaker base. Otherwise, you are listening off-axis and no lateral movement of the speakers can compensate for the difference in sound.
Seriously, concrete blocks are one of the best methods of dampening your system. It doesn't take much creativity to disguise them, i.e., a wood surround, or paint, etc. In fact, all of my amps (10 of them) are now on concrete blocks approx. 2 feet high with a polished wood base under each amp. As for the sofa, I really don't notice the difference (I'm 5'10"). It seems the sofa designers make the legs as short as possible to accomodate the widest range of height differences. Interesting how we assume that things as they are, are as they should be.
