For $6500 you can do better then an ARC DSI-200. I heard the 200 driving a Magnepan 1.7 and was disappointed. The ARC produced a fake type of "sweetness". This was an early production model, maybe ARC has improved the sonics? Since I have not heard the Synchrony One I can't zero in on any specific amp. I would look into an amp on the slightly warm/dark side of neutral-BAT/CJ/Coda/Electrocompaniet/Marantz/Nad M3/Quad 909/Roksan.
