Suggestions for power amps

I'm at an impass too... have Audio Note AN-e/sp, Aesthetix Calypso Sig paired with a Canary M-90 300b power amp. It's really very good but always wondering about amps. I'm all in on my pre & speakers and have enjoyed an all-tube setup (even DAC) for a long time now. Did really enjoy a Chord, SPM 600 in this same setup at one point but wondering who's had a kit anything like this and what they found to be a winning combo, and why.

If you haven't tried adding a sub, I would recommend it.  A good one should expand the soundstage and fill the room with sound.

Schiit Tyrs?

With Pass X25  for solid state this is an amazing amp.For tubes My friend likes Aric amp. 

Ideally it would be best for recommendations to know if your power is supplied by coal, hydro, wind, or solar. The "greener" the better. Also, do you have any isolation devices under your equipment? Some amps respond differently to granite than they do marble or wood. What about air purifiers? HEPA is best because they remove the smallest particles that could affect the way the amps dissipate heat. A room full or non-treated air is chock full of things that make heat sinks work harder. 

If you (generally) think any of that seems ridiculous, just imagine how you sound asking about the "sound characteristics" of an amp or interconnects or the other commonly heald but wrong beliefs.
