Best power amp to match Sonus Extrema speakers


Looking for an amp or mono-block amps to match a pair of Sonus Faber Extrema speakers. Wonderful & Incredible speakers but very inefficient to drive. Need an amp with guts and finesse.

Should I go tubes or SS or Hybrid for power amp ?

Budget is under 10K on the used market.

All the best to help my situation.

My goal is to own that same pair of speakers, and I intend on driving them with a Levinson 23.5.
LAMM, Gryphon, bigger Rowlands - guts and finesse.
With LAMM and Rowland support is excellent. With Gryphon you may have to ship them to Denmark if something goes wrong though there might be a distributor here, I am not sure. Which one? It will depend on your preferances. Personally I would try LAMM first and probably Gryphon second.
