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 own a B&K ST-140 that I use as a backup amplifier. Stock, it does sound really warm, and a little undetailed.

However, a quick look at the schematic and you'll see a gross little electrolytic used as the input capacitor. I replaced this (and the power supply bypass caps) with some Elna Silmics. It was a big improvement in the sound, making the amplifier sound more open.
