Downsizing from Audio Research REF110 to 100.2

I have an Audio Research REF3 and REF110, I pair them with Proac D38 and Transparent ultra MM biwire speaker cable.

I want to keep the REF3 but I am going to try the very well reviewed solid state Audio Research 100.2, I like the REF110 but I want to have more simplicity in my system and not to think about if my power amp in switched on or not.

I also wanted to convince myself that I am not such exigent to need always the best, I had in the pass an Audio Research D200 which left to me good reminders, I know that 100.2 in noticeable better so I think it could be enough satisfactory in my system.

Someone having some experience with both amplifiers?
How they would compare?
