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.

My friend is currently running a B&K Pro 10 preamp, B&K 2020 amp I think, Marantz cd player.... powering MMG Maggies. I hear no such mist. Sounds detailed and clear to my ears. Seriously, I've heard much worse in systems costing 3 or 4 times as much.
Ok I get it. Nothing more than a twist of words. Just thought I would ask. Thanks and enjoy your mosfets : )
There is nothing wrong with mosfets, many Conrad Johnson amps used them. Their rugged and require less circuitry than bipolars plus their tauted as sounding tube-like. Some of the best sounding amps I have heard use them. I could never identify the elusive mosfet mist. Maybe I heard it but it never got in the way of the music.
