I have my LFR's, VP180HP, and 2 QS8's bolted up to an Arcam P777. Love the sound with the Axioms as I wanted to feed the LFR's the most clean power I could afford. It specs out close to the Anthem A5. I like modern/classic rock at SPL's that make the instruments sound "real" and the Arcam provides! I'm using unbalanced connections with no ground noise. May go to balanced when my new room is built in our new house this fall. Then I'll have no less than 4 QS'8 I'll use my Arcam P1000 amp for those. It was able to drive the LFR's also but sounded a little lean. Brad
