A lot of folks think using mosfet drivers and bipolar output transistors give you the best of both worlds. McCormack and Theta are just two prime examples. People use to gripe about the mosfet haze but I guess times change. I think Jfet's are used more as an input amplifying device. I know there impedance stays constant over a wide range.
Mosfets: The way to go for SS amplification?
OK, why? Advantages and drawbacks? I've done a "search" here and elsewhere and not gotten a good answer as to why it may be superior to JFET, for example. And, are balanced ics the "only" way to go for Mfs...if so, why? Thanks in advance (and may Santa leave a pair of Plasmatronic spkrs. under your tree).
