Mosfet mist?


Greetings,

I have read several articles on the sonics of mosfet amps to include Adcom,B&K,Counterpoint,Perreaux,etc. What exactly is mosfet mist and how would one know what to listen for. Are some amps more prone to this mist than others? I have a Perreaux 1150B doing woofer duty on a pair of Focal 706s spkrs(A modified Parasound 1000A on top)How would say the 1150B compare with a B&K in relation. Thanks.

I personally like the more tube like sonic signature of mosfets vs bipolars. I recently acquired a Counterpoint SA100 rebuilt by Greenstreet Audio with Exicon mosfets and with some tweaking and replacing of the coupling caps @ the tube gain stage I'd say there's hardly any mist I could detect and all there is is music.
I currently own Vac Phi 70 mono, Counterpoint Altavista NP220PG, NP100PG, and some heavily modded/rebuilt tube amps.
Mosfet amps are given a bum-rap by designers not going all out to do them justice by using up to par components in the gain and driver stage. Fix all the problems upstream and use modern mosfets that are less lossy and you wont need to burn money with power tubes (esp. those Sovteks passed off as so-called whatever brand reissues)
