I went through this same situation about three months ago. I called and spoke with Albert Von Schweikert and he recommended a tube integrated to me. I came from a class A SS amp and thought I wanted to stay with SS. I could not be more satisfied. This is my first tube amp, although I have had several tube preamps. By the way, Albert told me he voiced the VR4.5 with Spectron Musician amps. Good luck.
