I also have the Sonic Frontiers Power 3 SE's. The power 3 series is an excellent buy at this time as the prices for the standard 3's are in the $3000-$3500 range used. These amps are very neutral and do provide power on par with many SS amps. I am using with the Hovland preamp and the soundstage is very wide, the midrange is extremely clear and alive, and the extremes do not seem rolled off at all. I agree with Alfina that these are not the amps for a lush tubey sound. If you are looking for neutrality they are pretty good at it.
