MOSFET's vs Bipolar's

"Mosfet Mist" is long gone.
.

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.

Lateral power Mosfets from Exicon can be drop in replacements for many types of devices supplied by Toshiba and Hitachi. The Exicons supply 30% greater current have much greater speed and lower capacitance. In my particular amp they increased resolution and impact while reducing the overall grain structure of the whole sonic picture. Tom

I don't know suitability for audio but........the opposite of 'lateral', which BTW, the majority of devices appear to be.

Also, Carver used IGBT from these guys in his Sunfire line....at least part of it.

No more than the difference between night and day in my neighborhood though some will say otherwise.Its a hell of a hobby as long as you dont obsess,cheers,Jack
