Summertime ss amp Question


My wife has finally decided that the superb Atma-Sphere MA-2 is too hot for summer and she cant listen to it without getting an ice bath in the room. But one doesnt part with a Gem of this magnitude, so I will buy an SS amp for summer only.
Need at least 150 WPC into 4 ohms (SP Tech Revs III sens 88 db), XLR inputs,(preamp Atma-sphere MP-1) fit into 17 X 8 X 19 inch space in Stereo closet and run cool, budget under $2K used. Looking at Innersound esl-300, Cary CAD-200 currently on A'gon. Suggestions, please. Thanks.

Raquel, it is amazing that you went to all that trouble! The only thing not current is my affinity for Jena cables -everything else is true! The Rowland 6 consists of 2 monoblocs, right? That would be a problem fitting into the cupboard space - any ideas of the dimensions? I will take your advice and look into Rowland. I appreciate your efforts greatly! There is a 6 on A'gon for $4700 and I have asked the seller for dimensions.
Springbok10 I also have model 6 mono's;best solid state amp that I have owned and I use them with soundlab m2's and usher rw729 monitors.
here is the size:
17.5 in (W) x 14.25 in (D) x 5.25 in (H)
