Solid State Power Amps

From your list I’m only familiar with X260.8. They drive my Wilson Sabrina without breaking a sweat. Preamp is Pass XP-22. I tried Audio Research Ref 6 tube preamp as well and the synergy was excellent. What speakers are you looking to drive with the new amp?

Focal Sopra 3 - not a challenging speaker to drive

Mola Mola Kaluga, AGD Gran Vivace, AGD Solo,

Electrocompaniet AW 800M, TIDAL Intra

Thanks - I don’t know these brands. I will look into them. 

Pass should pair well with Focal Sopra 3. The PS Audio should also be a good match based on what I read. You don’t want bright or forward sounding amps with sopras.
