    I would like some intelligent opinions on MOS FET amps. I am considering one and have never used one.

    Well, for starters MOSFETS are a type of transistor that switches faster than standard transistors. This means that they run a lot cooler which ultimately makes them more reliable and longer lasting.
     
  3. I know alot of car audio amps use Mos Fets. I don't really know if many bass amps do or not. Later!

    Woffy Out!
     
  4. There's absolutely no distinguishable difference in sound between mosfets and normal (bipolar) transistors. Mosfet are just a different type of transistor. When applied in a certain way, they are a little bit more efficient.

    The name says it all. Mosfet stands for Metal Oxide Semiconductor Field Effect Transistor. Just a transistor. No special stuff. Your computer holds millions and millions of'em .............

    Hey Joris ... don't most modern solid state power amps use MOSFETs anyway?
     
  6. True. And most brands don't put it in their specs, cause it's nothing to be bragging about, there's nothing to brag. Fortunately, real tech heads know there's no difference. A few years ago, mosfet were the latest (solid) state of the art technology. At the recent speed of developments, probably another technology like IGBT will take the lead in advertisements, or Triac, Thyristor, PWM, Class H, or whatever sounds interesing.

    (IGBT=Insulated Gate Bipolar Transistor, a combination of a mosfet and a bipolar [normal] transistor)

    Now, are these IGBT's doped with lithium?
     
  8. Wha?

    I was afraid of this ... bipolar disorder ... lithium is the medication. It was a stretch. I thought at least one person would get it. Never mind.
     
  10. Please note: I'm Dutch. Most puns are wasted on me.... Nice try though. :D:D:D
