I will repeat my own experience...
Many past s.s. amplifier presented harsh sounds, not my two S. S. Sansui amplifiers...
The only Tube amplifier i bought was someway harsh sounding ... it was a relatively low cost one ... I sold it ...
I think that well designed tube amplifier cost more than few hundred bucks i guess..
All S.S. design are not equal , as like all tube designs are not equal...
