I've only heard them once before but I was completely blown away. Wonderful tonality and powerful dynamics. I'll of course post more impressions and pictures after they arrive. This particular pair is a demo pair with very little use, I paid $2850 shipped they are $5K new. I'll be powering them with a pair of monoblocks that use the ICE power modules that are used in all the belcanto, ps audio, etc amps these days.
