Integrated amp suggestions.

I would look at The Krell K-300i Nice match for your speakers. The Audio Research VSI 75 would be another match. Based on your current configuration you owe it to yourself to give the MC 300 watt Integrated. The MC sound is unique and it is a matter of preference.
Making the move to an integrated took me a little while to get used to.
The good news is you have the most significant part of your system . The speakers are phenomenal!! On your speakers you will be able to evaluate the amp that suits your preference. 

The  Dag Progression integrated is the antithesis of cold, lean, bright or any other non musical term that one might use. Mesmerizing on vocals.

"Ayre has a certain darkness, like it pulls noise out of the room. It’s kind of a funny effect. Very smooth, touch warm in the sense of Parasound."

very apt description of what ayre does... so true... i wouldn't call it a drak sound, but there is a blackness to the background that is quite unique

Exactly!! It is not tonally dark or warm. 

I just got a Prima Luna Prologue Premium (floor model). I love it. The new Prima Luna line - EVO, I think, is supposed to great.
