Best power amp to match Sonus Extrema speakers

I would suggest a Pass X-250 or Pass X-350.

Meridian 557 amps bridged.
McCormack DNA-2 Deluxe Revision A amp
Theta Digital ENTERPRISE MONO blocks
Llano A-300 mono blocks
Classe Cam 300 amps.

I also forgot to mention, I wouldn't use tube amps on the Extremas. The Extremas need lots of power. I'v found high powered solid state amps sound best on them.

I currently drive my Extremas with Convergent Audio Technology JL-1 Monoblock tube amps using KT-90's as output tubes.....in one sentence they are the sound i have been searching for in my 30 years of being an audiophile!...i originally mated the Extrema with Classe CA-301 and they sounded very thin and lifeless with linited dynamics....do the research and you will be happy you did!...you can e-mail me with questions.

I used the Extremas with a pair of Linn Klimax 500 monoblocks (290 WPC).This combo was superb: amazing speed, dynamics and "slam". The midrange was very natural and fully textured and the refinement in the treble simply incredible. No harshess, brightness or edginess - just beautifully smooth, natural and involving presentation. The Linns are IMHO some of the best solid state amps avaiable. They can be had used for a little less than 10K although they don't show up here often.
Good luck!
