It really is a wonderful piece. They offer a trial and well worth the effort. I am not sure how to best hook up your sub, etc.. But, it's not expensive enough for some 

Dang, you got me thinking about the MicroZOTL2.0 Joe. The only thing that might be a problem for me is I wish it had 2 or three outputs. To the Job 225 (yes I have fallen in love with this amp again), but also to the sub, and would be nice to keep the Bryston BHA-1 hooked, but that can be handled by switching cables... the sub might be an issue though.
