MOSFETs have no place in an audio signal path, IMO and IME. None! Been there, done that, and left!

They simply sound ugly, due most likely to their variable input gate capacitance with signal level.

If you want to use DHTs, then use them in the circuits they work best in, there are hundereds of possibilities out there, mostly proven by tests of time. I'm not against such circuits and tubes, they are just not my choice for production.

If you want to use "modern" (post WW2) circuits like cascodes, use suitable tubes.

If you want your audio to sound good, forgetabout MOSFETs!
