Chorus, I used to like my SS amps a lot but when I moved up to very revealing cables, my SS amps do not sound like music as much as my tube amps which are 300b, EL34 and KT66 based. The Threshold SA line and “T” series are truly wonderful sounding SS amplifiers and awesome in every way. The long history of online comments on these amps speak for themselves. But ultimately, it’s which amp sounds best in your system. BTW, I’m sorta bias in that I’ve experience quite a bit of components that were very expensive and did not live up to a high standard. I like to stick with what has been proven and tested by many many to be top performers.
