MOSFET's vs Bipolar's


All else being equal, can one truly hear the difference between power amplifiers driven by MOSFET or Bipolar transistors? If there audible differences, are they due more to circuit design and other parts quality? Thanks to all who reply.

I think the heart of the answer is in your second question, the circuit design.

I'm a big fan of Nelson Pass's designs and he uses Mosfets but I have a Bedini 45/45 amp that uses bipolars and it's very sweet also.
I have often read that Mosfets are often the choice of transistor amp designers who mean to emulate certain tube virtues.... Hmm.

One can also read that fuzziness, softened transients, smoothness/warmth and a small degree of thickening are also hallmarks of Mosfet Mist.

While I have owned Mosfet amps for which the above is certainly true - it would not be right to characterize all Mosfet amps that way.
