You should try Atmasphere. They have a 160 watt I think the model is M-1. It's an OTL amp., but do'nt be fooled by it without investigating them. This guy Ralph I think is his name, has been around forever and has a cult of beleivers with very good reason.The m-1 goes for around 10 grand new and less if you are lucky to get it in the used market. Very reliable stuff contrary to the usual idiosincracies of traditional OTL designs. I personally use Lamm m1.1 on my Parsifals wich is as close as you can get to Atmaspheres without going into tubes fully which is something I have'nt convince myself of doing yet. But if you do'nt mind tubes, do yourself a favor and check out the Atmasperes.
