Which one is the best INTEGRATED!!

I would definitely say the Gryphon Diablo, I know it well and will say that it would be a great middle for your source and speakers. I have heard it with the Esoteric 3 box system and Gryphon Pantheon speakers awesome is the only word I can come up with. It can also handle any kind of music you care to throw at it.

You did not state your budget  his loud you play ,speaker efficiency.

Fm acoustics , Ensemble -Swiss made great and priced under $10k, Audio Archon.sells Ensemble., 

I’m in the same spot.   I have Focal Sopra 3s and just ordered a Gryphon Diablo 300.  Should be here in a few weeks.   I’ll let you know how it sounds.   Hopefully there is good synergy.
