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.

Mosfet is solid state. It is a type of transistor.

Even tube is not tube. The sound you get depends on what tubes you use. Their is no direct correlation between Mosfet transistors and tube like sound.

For example; the current crop of Conrad Johnson solid state amplifiers that replaced the MF2100 (and others) use Bi-Polar output transistors instead of Mosfets. They also use Field Effect transitors because they handle voltage in a way similar to tubes.

So just buy an amplifier that you like the sound of; and forget the buzz words.

You may want to try a tube preamp with a solid state power amp. It is a good way to get the best of both worlds.
