Replacement power. Ps

Not interested in a switching amp. 

Would like another pair of mono class A amps. 

It looks like the Lamms are 100 wpc amps. A good 60wpc (or more) tube amp/amps might be a way to move the sound in a better direction. However the Lamms are well respected so it might be hard to do better but tubes might take you in a new direction.

I’ve always thought Clayton Audio amps were some of the better Class A solid state amps around and quite a value for the performance they offer.  Here are a couple reviews for their M200 mono blocks and S100 stereo amps FYI...

Audio Research Reference 160m monoblocks or 320m (I gather shipping in the next couple months).
