It's cool that you got to hear it. Pics?
It's funny because I've seen plenty of threads about "Why don't any high end amp manufacturers make headphone amps?" Yet here's an example of just that. Granted, Icon might not be priced like Lamm, Atma-sphere, Jadis, etc. But still.
I was just checking out the Icon MB90 monoblocks. Those look mighty tasty for $4200.
Or, how about the Jolida Fusion monblocks? Oh darn... That's $2999 ea.
