There is a SE cathode follower design in Bruce Rosenblit's book "Audio Reality". It used 3 KT88's in parallel to produce about 25 watts per channel. I heard one of these amps several years ago, and was impressed with the bass and transient response, but it was in an isolated setting. There was nothing else to compare it to and the room was fairly large, big speakers too.

I stumbled upon this review of the Cyrus Brenneman Cavalier mentioned in post 8: http://www.enjoythemusic.com/magazin...sbrenneman.htm

In engineering the Cavalier (and the more expensive Reference 20 monoblocks), Cyrus Brenneman has sought to overcome these traditional shortcomings of SE designs. In doing so he has blazed a new trail in SE amplification by incorporating an innovative cathode follower output stage. Although a rare beast, such a stage is occasionally seen in high-quality preamplifiers where its low-output impedance and inherent linearity makes it an excellent line driver.

And now, with 100% negative feedback by voltage in output stage, they will claim that their apparatus contains no damned dirty feedback producing brightest lows and smoothest highs through the whole olfactory palitra right in the midle of an elevated soundstage.

I played with tubes and gave up the idea because transistor followers loaded by converters of voltage to current are the best I can think currently about, both sonically and to satisfy requirements of people crazy on measurements.

You gotta learn to STFU, you're gonna blow the whole deal.

What is STFU, a kind of hypnotic language?
