solid state amp power

Currently I have an LFD Mark IV (60 watts) driving a pair of Harbeth C7ES-3. I've caught upgrade-itis. I'm thinking about going to the Super HL5-Plus and if I do that I'm going to replace my whole system. The reason being that I want to use a PS Audio Direct Stream DAC as the source, in which case I no longer need an integrated amp. I want to try running the DAC directly to an amp. My question is then, which amp to get?

I want to use a solid state amp but I'm finding it diffictult to find an interesting amp that is not integrated and produces less than 100 WPC. Additionally, I don't want an amp that runs hot at idle. Currently I never turn my LFD over 30% volume unless I'm listening to it from the next room so, even 60 WPC is far more than I need. 

If I can't find an amp I like under 100 WPC, I may try the Classé CA-D200, which is 200 WPC. Is this powerful amp going to be too loud for me at even the lowest settings?

Any advice is welcome.
