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).

IMHO, it's not necessarily the parts, but the sum of the parts that matters.
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.
Hafler claims that MOSFETs have several advantages over bipolar transistors: better thermal stability, faster switching speed, lower output impedance and better linearity.

From Stereophile December 2002: Musical Fidelity uses bipolars because "they have a higher current yield than mosfets".
If the Plasmatronics are the speakers I remember seeing, won't they set the tree on fire? Aren't these the speakers that needed a gas supply to run? Or was it that they emitted a gas from their plasma tweeters?

Cdc - the "current yield" is the transconductance I talk about in my post above. There are a few more details about it there. Arthur
