Amps for Avalon Osiris CAT JL3, Boulder 2060, Dart

I recently purchased Avalon Osiris and am considering what amps to use with them. I purchased a pair of Levinson 436's as a stop gap just to have an amp that could drive them while I saved for a better amp. I am using Stealth cables throughout (Indra IC's, Dream PC's and Dream SC's).
My preamp is CAT Ultimate MK2 (line only) with NOS Amperex PQ's. My DAC is Audiologic 24MXL and CEC TL2 transport. I am open to other amps than the three listed above but am leaning toard solid state or hybrid. I am trying to avoid space heaters. Some other amp considerations are VTL Sigfreid, Tenor 300's ...

FWIW
I have had both CAT JL3 Sig and Atma-spere MA-2 ( i belive Rushton now has the pair I owned).
I fully agree with Essentialaudio: the Cat's have fantastic bass but are not up to the std's of the MA-2's in the midrange. They are, in fact, a little lean in the MR.
You always have tradeoffs to make. Cat is closer to ss sound than most tube amps.
There is no getting around the thermal issues of tubes, especially Atmas-speres as they run true class A.
