I've seen their advertisements and several write ups on the topic. It looks very interesting. Do any of you have any experience with it? The Denon 4806 might be a very interesting receiver since it has the MultEQ XT and is somewhat affordable (~$3k). I hope it trickles down to moderately priced, digitally amplified receivers; if it also included proper bass managment, HDMI/DVI switching and a good upcoverter, that would be unbeleivable!
