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.
Mike, Do WHATEVER is necessary to get the sound you want. I had some Hales Revelation II's (with concrete baffle -wish I had them back) that didn't come to life until I put them on bases composed of (from ground up): 12" X 12" X 1" patio slab, two full height cinder blocks, another patio slab, two half height cinder blocks, topped of by, U guessed it, another patio slab. This was in my living room. EVERYTHING snapped into place when I removed the front cone (left rear two in place). So much for short speakers...
why not simply replace your floors with concrete? maybe granite? it'd be much more aesthetically pleasing. my god, who but an 8 footer finds it comfortable to sit on a couch raised half a foot from the floor? com'on guys, this is the sort of stuff that makes 'philes sound even more like freaks 'n geeks.
