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.

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.

what do they call a fog over italy ????

a bigamist.

as to mosfets, it's all in the design. odd order harmonics are an important consideration to the sound of a ss amp.

i would conjecture that all mosfet amps do not sound the same, so don't be too concerned. listen and decide if you like the amp, not its component parts.

Play Misty for me! My Meridian 605s have Mosfets and I haven't heard it. I use to sell Hafler and Hitachi power amps and never thought they had sound deficiencies due to Mosfets. I think my CJ Premier 350 has them in its driver stage and my tube using friends think it is a great amp.
