I've never heard my system come this close to bringing the magic of a live performance into my room. It has that "electricity in the air" feeling you get when a concert begins and the first notes are played before the lights come up.
I've been watching Real Live Roadrunning with M. Knopfler/Emmylou Harris and the depth of the soundfield is simply stunning - layer after layer of music and detail should you want to "look" for it - but never shoved at you. The "realness" of their voices also jumps out at me.
Speed, delicacy, drive, texture, imaging, clarity, detail, smoothness... I could go on and on but I'd rather go listen some more.
I've heard great things about the Bel Canto gear too - but have no experience with it.
