I used to own (wish I still did) a DNA .05 that I had upgraded to the Rev. A. It was (and still is, I'm sure)an outstanding amp in every respect. SMC is very easy to deal with and Steve is easy to get in touch with. I wouldn't hesitate calling him at all. I have changed amps several times just to get different flavors for my own experience, and unfortunately I couldn't afford to keep the DNA and buy anything else. Still I have nothing but fond memories...
