almost all modern electronics uses MOSFETS

Uh ! Pardon ? The amplifiers I've been associated with in recent
times have actually stopped using Mosfets as output devices and
we're using bipolars again ( cost reasons - and limited sources of
nice lateral mosfets ).

Not a single mosfet in the signal path.

Care to elaborate ?

Two words: digital audio.

Stewart was talking in the present tense. All modern electronics ( at
least audio since this is an audio group ) use mosfets very
sparingly.

Why isn't it appropriate to speak of digital audio in the present tense?

I assumed you meant 'digital amps'. Not *that* mainstream yet.

I expect most digital source products use CMOS technology for digital signal
processing.

The analogue path rarely uses mosfets however.
