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

Nice choices. I would look at the pass and Hegel only - I am not sure the luxman is the same level imo.  then it comes down to what speakers you are driving as these are pretty different amps. If the speakers would be good on lower power, and you like class a sound, the pass would be great. The Hegel is probably more versatile in terms of matching to different speakers if you plan to switch over time. The Hegel also runs cool. But both are really top notch. Enjoy the search. 

Thanks a lot :) Speakers are the Goldenear Triton One. At 92 dB and with the active bass section they are not a difficult load (the room is not big as well). The Hegel would be my choice taking into account:
1) Price (the least expensive, at least in Europe)
2) Versatility, like you mentioned (if and when I change the speakers)
Having said this, it's more about the absolute sound quality that I'm more concerned about. In a perfect world I woul be able to compare them ... in the real world I can't. I had a very revelatory experience with a Pass Aleph 0 many years ago ... but didn't manage to listen to the .8 series ...
Thank you! :)

btw,  skoczylas, have you auditioned the Luxman? In which way is it below the level of Pass and Hegel?
