Mosfet amps A true compromise betw. tubes and SS?


I heard from several people that Mosfet SS amps are a nice compromise between tubes and SS amps.
There is one manufacturer in particular I am interested
http://www.wbe-audio.de,s croll down to Fusion 700 (its a German made amp, but he has an English web page) who calls his hybrid amp a Mono tube mosfet amp.
I would really appreciate if someone who has more insight would tell me a bit more of advantages and shortcomings of this design and if the claim: "sound of tubes with power of SS" is true or not. Also I would like to know if these are fast amps, as I plan to maybe use them with my ML Prodigy, should the Wolcott amps, I bought recently, not work satisfactorily.

Hi Will

I would be interested in your list of good tube amps that fall short of ss in the areas of clarity, speed and dynamics and even detail, my you have me curious. You might want to hear a good OTL design with a proper load to put that assumption to further test. This aside from your preference of ss over the warm, even ordered distortion characteristics of tube circuits. btw, the Atmas-pheres have among the fastest slew rates of any amp, period.

I am a big fan of the Counterpoint hybrids amps from the 80's. Mike Elliott truly got the best out of those designs other than their tendency towards premature failure (mosfets). The SA-100 was the best 1K amp that I can recall in its day.
