Absolutely beautiful system! I imagine it sounds just as nice. I heard the Stein Harmonizers at the Capital Audio Fest last year (in a system with Harbeth 30.1 speakers) and was very impressed, but of course there was no way to separate out the effects of the Harmonizers.
I am curious about the maple platform. Is it made from solid maple boards or is it maple veneer covering plywood perhaps? And what type of footers do you use between the bottom of the maple platform and the floor? I have been thinking of building something similar.
