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.

Dividebytube,
I seem to be hearing the same thing inre electrolytics.

After living with my CJ ART preamp (no elecs anywhere), every pre (with elecs) that I've tried since seemed to have a certain "sour?" sound. Latest experience was with a DAC. A friend offered me one of his personals. He helped design the DAC but in his personal ones, he took out all the elecs and replaced them with polys. I've tried a few well reviewed (fwiw) DACs since then and each one, while slightly different, had that "sour? sound. Coincidence? Don't know, works for me.

I'm also a fan of bypass caps on the big PS elecs of power amps.
