@moto_man when I tried the Alpha V2 it was on the XA30.8. It did something strange to the high frequencies that irritated me. I was planning on replacing the AQ Hurricane with it and kept the Hurricane. However, the AQ H didn’t work as well with the X260.8 with its big full sound so who knows…synergy is a strange beast.
I like the XP22. I upgraded from XP12 and was actually debating between Ref 5SE, Ref 6 or XP22. Couldn’t convince myself to go back to tubes yet. The 22 is quiet, dynamic and still remains very natural sounding. However, the Ref should be a great combo with Pass amp. I used Ref1 with X250.5 years ago and it was phenomenal.
