..., with its high gm, be as good as or better than a tube..."In my experience - no fet, either junction or MOS, should be allowed anywhere the primary signal path in any amp!
The only exception is the use of a very low noise jfet as the lower half of an cascode in the input of a RIAA stage. There the greatly reduced (and consistantly low) noise compared to any tube is a huge benefit - and it seems that the sonic contribution of the jfet is effectively inaudible.
But a MOSFET source follower - nein danke!
If you really need a CF driver - the ONLY thing that I would use is my SLCF - that is transparent and with enough current through (say) 6H30's will drive most anything you want - including 30 ohm headphones!
