Yeah, if I had your system I'd probably be pretty content too. I'm happy with my setup, it's a bit smaller than yours, but you must get really big, smooth sound top to bottom. You friends must love it too. Or are they as sophisticated a listener as you?
I've heard another person talking about Dupont Corian, is this similar to MDF? Can you get it at a place like Home Depot? What type of wood did you use for the support posts, is this the area your thinking of switching to stainless steel?
