I for one will never use a SS amplifier (or preamplifier). It is all
tube for me except for the dac. There are just inherent problems with
SS that cannot be solved.
Tubes designs are a completely different story. I have described some of
the inherent problems with SS in another string called "Solid State vs
Vacuum Amps", in this Tube subforum.
I finished up my phono stage (except somewhat haywire look) and I do find
some LPs superior but costly, to high rez ss dacs).
