The OP didn't specify if his question was restricted to those switching from a tubed power amp, preamp or both. I previously owned a tube preamp which I ran with a ss power amp as I do like a little tube magic. The amp which struck the right balance for me between tube and ss virtues is my current amp; a Vitus SIA-025. Vitus class A amps sound quite unique as they are so pure and mellifluous, yet at the same time controlled and resolving. I have a sensitive ear, and Vitus is one of the few amps I can listen to for hours without fatigue.
