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.

How about Jadis JA200's or something big and mono from Paul at tube research labs?
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.
