Want to replace RED Dragon amps with stereo amp

I have a pair of Red Dragon M-500 digital monoblock amps. They are 250 RMS. They sound very good but I am downsizing, and want to get rid some of the boxes. I was considering going to a quality integrated amp, but I love the BelCanto PRe3 pre-amp I have. So now I am leaning toward a very good basic stereo amp of 100-150RMS. I don't want a monster amp because I have serious back problems and can't lift a monster amp. So looking for suggestions and advice.

Would prefer a quality SS stereo amps, but would consider a tube amp. (Please no Wyred4Sound products). Would seriously consider the Odyssey Khartago, but am not sure I am not dropping to a lower quality sounding amp and performance Thanks.
