first for a good power follower you need a
ccs (constant courant source) not just
a source resistor

and the best driver is a tube driver with
very low zout 50 ohm in my case

maybe more explication

a source follower with ccs is very good :

low distorsion without feedback
good widthband

but the sound is very neutral and to get a good
amplifier you need to add some personality :-) to
the sound

a good way is tube (triode not pentode) with
even harmonics

don t forget if you go with transfo you need a equivalent
low zout 100 ohm max. to drive your output follower

but for me sorry :-) double follower= double neutral sound
