Musical, high powered Amp under $1k


I'm looking for a new (used..?) amp around $1,000. So far I've liked the anthem HCA 20 amp the best between my modded Acurus a100, and a Mcintosh MC 2105 (first taste of Mac and I was very unimpressed).

Anyways, it seems both myself and my Paradigm Signature 2's V.3 like a more powerful amp, like the Anthem, so with that in mind, what amps should I be looking at? I'm thinking I can get something as powerful as the Anthem with a touch more air and sweetness to it, for the same $ the anthem would cost me $1100 (ouch).

Usually I can find a few amps in the $1k range that look tempting but I'm stumped right now...

Belles 150 any iteration, any McCormack, Sumo Polaris or Andromeda. All those are great amps and where the principle of diminishing returns on dollars spent starts to kick in with more expensive amps. My opinion only though.
I have Outlaw Audio mono blocks and they are articulate and powerful enough in my system. In terms of $/watt the Emotiva are currently King, although I haven't bought one. They are well liked and well reviewed.
