Have been running Arcus for past year. My last set of speakers--stage from wall-to-wall, superior depth and height (tough to get with many speakers/systems), excellent bass, outstanding mids and highs, very smooth, dynamic and balanced; above all--musical. Probably the finest two-ways I have ever heard. However, these attributes don't show to their best unless you have adequate power. Avalon says 50 wpc is minimum; I'm running 125 pc. OTOH, I've heard the Arcus driven by an Accuphase A-50 (50 wpc class A) in a room approx 18x28x10 and the power was more than adequate at high spls. But you're also looking at a $14K amp with high current delivery. Balance of my system: c-j 14LS, Accuphase DP-55 CD player and T-109 tuner, Goertz Micro-Purl interconnects and SYMO (Swiss) speaker cable. Hope this gives some insight. IMHO, you could buy the Arcus with confidence and never look back. As to system compatibility with your gardware, you'd have to audition it all together. Good luck! gino
