Well, I got to hear the XPR-1 driving those LSiMs, with a stand alone version of DIRAC in a fully balanced system. That room impressed me the most. XPR-1 are beasts I tell you. Got to see and hear the XPA-1L, which I've considered a pair of.
Got to see and hear the XMC-1 and I was pretty darned impressed with it, though I really would rather have won one than have to buy one

(
yes, they gave one away!). XMC-1 on the top there. An XPR-5 and some 1Ls for power and an Oppo in there.
