Maple platforms

3" solid maple butcher blocks cut to 18" X 20" are amazingly good under a table, I use one, its routed with rounded corners with a clear coat of some type.. using my table directly on it with the stock Spikes sticking into the block proves to be the best I have heard, and the block is sitting on a mdf shelf, but not directly it is seperated via rubber feet... I can fire my massive sub's 2 feet from the rack and you cannot even get the stylus to mistrack, jump, skip whatever at outrageous levels, very very solid and yes sounds far warmer and at the same time solid detail with clean image. So for how much you can get these things cut at a local butcher shop(I paid 100.00 totally routed and finished) they are I believe the best value and effectiveness... I would never use any stone under a turntable or digital, horrible results. Also, I use a 1.5" thick solid maple cut the same deal as the 3", and works very well under my tubes and Digital as well. all for around 200.00 total cost 3 shelfs, and everyone thinks they are bought from a hiend manufacture, all I need to do is tack on a little gold emblem or something and could go into business selling these for 4 times the price. Now I want to maybe work on bolting the turntable shelf to the wall directly any suggestions?
