Pass XA30.8 vs Luxman m600-a vs Hegel H20

All the amps you mentioned (with the exception of the Hegel, which I haven't heard) is world-class, IMO. I've been particularly impressed with the upper-end Luxman gear, but the Pass 30.8 (with the right speaker load, which you have) is top-notch as well. I don't think you can lose either way. The Luxman MIGHT be a hair richer-sounding than the Pass, but the 30.8 MIGHT have the edge in ultimate resolution. This is just based on my very informal listening experiences with the two of them, so take my opinion with a hardy grain of salt..

You're very welcome, Vermeer. As I understand it, Reno Hi-Fi is good about letting people audition Pass gear. Maybe give them a call?
