I still fondly remember my old MC2100 amplifier, made in the 1970s. I had it restored by Terry DeWick before he retired, and I for damn sure should’ve kept it. Ugh! Kicking myself over that.
There’s been both good and bad sounding solid state gear, ever since it was introduced. There always will be. One problem with solid state is that good sounding audio-purpose transistors often go out OOP (aka "obsolete"). It’s a much worse problem than with tubes. With tubes it’s also harder to make something that sounds bad - you have to really mess up.
