In Reply to: Solid State Power: MOSFET vs. Bipolar? posted by Duster on October 4, 2010 at 13:26:32:
I have found that JFETS and MoSFETS can be nearly invisible sounding in lower current applications (as input and driver stages), especially when used like a triode: single ended, Class A and no negative feedback. Somehow they still don't sound quite as good as a properly done tube amp but much better than bipolar amps.
When used in the typical Class AB, high feedback and complementary designs then I would say that MOSFETS seem to underperform compared to the best bipolar output stages but both sound bad.
The FET is a closer to tube substitute and when used in that way it can sound very good.
