marble or granite slab under floorstanders?


Anyone have advice on whether to go with marble or granite ?

I'm looking for a custom size made, where's the best place to buy from? Thanks

Don't know which or if either are best under floorstanders. To your second question, I'd suggest checking granite/marble/quartz countertop companies near you, they usually have smaller remnant pieces that they can cut to size
Helmut Brinkmann uses 2-3” thick granite under his Model 7 Vandersteen speakers at the Munich audio show and most Of his electronics have an integral Granite base w exception of tables where HRS Designs purpose built bases w constrained layer technology. @ctsooner has a pair of Quattro on granite to great effect I hear..
Definitely Granit. From a countertop store that hadles stone tops etc. Google it in your geographic area.
You might also want to consider a 3" or 4" thick maple butcher block sold here on Audiogon.

Go to a counter top dealer...they have scrap pieces to fit your needs Cheaper than a audio dealer....The same product....
