Jeff Rowland Model 1

Yeah, made famous by ROCKFORD FOSGATE. CAR STEREO. Listen to some dance, rock, electronic with MOSFETS compared to BP . Krell, Mark Levinson the last time I checked aren't using MOSFETS

Really ? Mosfet mist ? Weak in the bass department ?

Don;’t know about the "mist" remark Mr D.

But yes for the same given complimentary pairs of Mosfets v (BJT) Bi-Polar,(both with great power supplies) the BJT output stage amp will deliver much more current (doubling down to 2ohms) into low impedance’s than Mosfets can hope to.
This is why you’ll see the reputation for best amps in the world that can drive evil loads that many of the great speakers have, are BJT amps.

Cheers George

George, as usual, you are talking about drive capability (specs ), into extreme low impedance loads. ( 1 ) I would never own a speaker such as that ( 2 ) There are many fine mosfet designs out there ( 3 ) You obviously feel tube amps are not very good, because they, too, cannot handle the extreme low impedance loads ( 4 ) jeffvegas is your new best friend ( 5 ) Amps using either bipolars or mosfets, can sound wonderful ( 6 ) Mosfets need to be driven differently than bipolars ( at least, this is my understanding ). Not every designer knows how to work with mosfets ( 7 ) Mosfet designs sound closer to tubes, which is a good thing, to many ( 8 ) As I said......to each his own....ymmv... .Enjoy ! MrD.
