Mosfet mist?

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.

The best way to collect and actually see mosfet mist is to first find a powered subwoofer powered by an internal mosfet based amplifier with no heatsinks for cooling on the outside.All the cooling has to come from the inside of the woofer enclosure.The powered subwoofer should also be a ported design with only one port to the rear of the box where the internal power amp controls are located.Leave your powered subwoofer in a damp enviroment such as a basement etc. overnight. Now you are ready to collect some mosfet mist.Take your now prepped sub back into your listening room and hook it up to your system and play some recordings with some deep bass like pipe organ and such.Collecting and examining mosfet mist is now easy.Get yourself a brand new dry and clear ziplock bag and hold it nice and tight up against the port opening of your sub while playing your organ music.It should fill up in no time with this very elusive mosfet mist.You should also now not only see this quite rare mist but feel it inside the ziplock bag.You may also fill a few to send to those unbelievers out there to quite them down.Mosfet mist,yes it does exist!!!

Don't knock Johnny Mathis I like him.

By the way Adcom especially the older ones, like the 555 used Bipolar transistors and they sucked. They were suppose to be the poor mans Krell, no way.

The 'MOSFET mist' is a term coined that points to the problems of driving extremely capacitive inputs of the output devices of a MOSFET-based amplifier. If the driver circuitry lacks the current to deal with this capacitance, there will be a high frequency roll-off, hence the term.
