Best power match with Sonus Extrema ?


I am looking for the best power to my new Extremas.
I use PSAudio PWDII and a Macintosh c2200 pre.
I would like to get the most neutral and detailed sound
I tried a few big "names" (Krell, ML, Manley) - no success.
Please let me know your advice.

Thanks,

Amnon

Sorry...for clarity's sake, i meant to type "...the Extrema is quite different from the Stradivari". i was referring to the fact that the Gryphon Antileon and Strad worked very well together. I do think the Extrema is slightly different as with the rest of that generation Sonus Faber. Still think Gryphon would be excellent, but note the differences in the 'voice' of the 2 speakers.
The Bel Canto REF 500 MkII are really nice. They sound similar to tubes but are class D. Very cool running and musical. Also Ayre electronics sound nice. I recently matched the Bel Canto with the Cremona M with excellent results.
Agree with lloydelee that the Gryphon is a great match with the Extremas. I just acquired the burmester 808 and 911 monos and they are also a superb match for my extremas. Have never heard the extremas sound so good.
Thf99, how do you like the Skaaning midbase on the Extremas? The Skaaning midbase on the Extremas is a Carbon Fiber Polypropelene midbase. This is the best sounding midbase I ever heard. It has a richness that no other midbase has. I like it better then the new Skaaning midbases which are 100 percent Polypropelene.
