Driving SF Extrema with one BAT VK-60 ?

Thank you all for your responses.

Twilo... The 300B amp that my friend use to drive Extrema is KTA brand. It's a Push-Pull 300b amp not a Single-Ended. Before he got the 300b amp, he used the Jeff Rowland Model 5 to drive his Extremas. He told me that Extremas sound much better with 300b than JR5. He also said no matter how much power solid state amps have, no matter how good they sound, they still sound like solid state amp, not tube. I didn't mean tubes are better than SS but my taste tend toward the tube sound. That's why I want to try tube amp.

i drive the extrema with levinson 23.5.
it's can be better sound.

Now I'm thinking about Sonic Frontiers Power3 monos. With its power rating at 220 watts/ch, I think it should be able to handle Extremas well. Should it be a good match? How well SF tube amps do compare with other Hi-end tube amps like BAT, Cary, Jadis, Joule Electra, and VAC? Thanks for looking.

And they sound wonderful as expected. I also tried all sort of solid state (Rowland 8TiHC, McCormack DNA-2 Deluxe, Classe CA-400, Krell FPB-300). You need to give Power 3 lots of current or your Power 3 can still clip when you push your Extrema loud. Another good choice is Pass Lab X-350 which is really smooth and sweet, almost as good as the Power 3 or any tube amp and that's what I own now.

When I auditioned my Extremas I heard them on two amps. A ca 300 and a Sonic Frontiers equvilant tube amp. I found the tube amp a little mushy with the Extremas. There are of course a hundred other reasons why that may be but I am curios what kind of music you listen to.

I mostly listen to rock so I ended up with two ca 400 that I run with MIT push pull cables. You run two 2 channel amps and it uses an amp per speaker direction. The Extremas love all that power.
