Actually everything you hear plus or minus about wood interfaces, lithic interfaces, or composite interfaces is so system dependent you cannot take anything other than your informed opinion about how the Granite sounds in your unique system. I trust your ears as much or more than anyone I know.
An extreme example of mass would be the Rockport table I saw in Seattle. (Thanks Mikel I am forever in your debt.) This table weights in at a monstrous 450 lbs from what I remember and 250 lbs of that is the lithic base.
I heard it with my own ears. No smearing allowed. This thing is so grounded you just forget there is a source at all.
I gotta think with all your mass below the stand, the Granite will provide a flat and solid interface to level the turntable. When I sold high end scientific scales, putting them on a slab of marble or granite was pretty much required in order to get accurate measurements. That and enclosing them so the air movement would not distort the readings.
I figure a needle in a groove needs the same type of precision interface. The more solid the foundation the better a turntable seems to sound in my direct experience.
I look forward to seeing you in July. The TD 125 looks pretty fine with that new unipivot tonearm. The granite looks like a perfect match for color.
Congrats on a nice Craig list buy.
