Best power amp to match Sonus Extrema speakers

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!

I owned Extrema for years as well, and I will recommend solid state for Extrema as much as I hate solid state. I had Sonic Frontiers Power 3 (220wpc) pushing them for most of the time, but 10% of music I played would clip the Power 3. I guess if I invest in dedicate outlets for the Power 3, it would not have happened.

Pass X600 will be my number one choice. At the time I had Extrema, McCormack DNA-2 was the best, ever surpassed Rowland 8TiHC.

Add high power Accuphase. Running P800 on them and don't feel the power is limited. Extrema loves power/current, the more the better. Normal size tube amps hardly get enough current unless you really want to afford tens of power tubes. Because extrema can and good at being loud, putting it in a reasonable large room with high current amps is the key.

Hi Semi,

With all due respect to Power 3, it not even close to CAT amps which brunogolf@aol.com is suggesting. JL series are rated 100W class A but the output transformers are 55lb each and have limitless power reserve, around 500W. Ken Stevens himself drives Wilson Grand Slamms without any problem with JL2. If an amplifier can get good bass from Grand Slamms, there are very few speakers in the real world that Amp can not drive. I own JL2 and I think it has the best of both worlds, SS and Tube. It is the only tube amp with the bass which can challange that of Symphonic Line kraft 400 monos(400W class A SS, the best bass on planet earth!) although does not quite get there.
Compliments to your speakers, I think there are the best Sonus Faber has ever made.

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