I've not used your amp but for 2200 there's alot to choose from. I'd try the Bel Canto Pre2 or the Edge G1. That's a very tough call as what your tastes are and what mine may be like are most likely different. I recently purchased a little know brand called Primare and so far like it better than the Krell KRC-3 I'd been using. The Primare is more rich and darker than the Krell was. Also the bass and lowest level detail seem to be greater. This is all in my system though. Pass, Ayre and Simaudio are a few others. You may want to tell us something about your system and what sound you like. One thing though is that if you buy used you won't take a big hit if you don't like it when you resell.
