Very cool room, rack and gear.
It's hard to tell from the pictures but it looks like your LV's are about 9' apart. That's very close to what I found optimal for my IBX's.
Transparent and musical are two words that I would also use to describe these speakers (or in my case the IBX's). I would also describe them as fun. Live jazz has an exctement that I have heard in very few speakers. Most other speakers seem too polite and boring to me now.
I find your speaker bases curious. I have been thinking about replacing the hollow LV bases with a thick piece of maple and spikes. Any thoughts?
