Is a Sonic Frontier Power 2 a "differential amp"

Can't tell you about the design. But it was one of the worst sounding amps I ever owned.

This review in Stereophile states that it is a fully balanced (differential) design.

Shakeydeal is out of line. I researched his thread history and he mentions that every amp he used sounded better, but never mentioned other electronics, etc. that would have an effect on the synergy of the sound.

What did you have in mind for the amp? I've heard it many times back when it was in production. Its very well made. Weather its the right amp for you really depends what you like and how you will use it.

I can tell you this. The Power 2 had an overwhelming midbass
bloat that was not there with the same speakers with at
least two other amps. One being the SS Mcormack DNA-1 Delux
monoblocks and the other being the tube Music Reference RM9.

Same speakers, same room, same associated electronics.

Nuff said.

BTW, I researched YOUR posts as well. Looks like I touched a
nerve with a SF Power 2 owner, LOL.
