Conrad Johnson Sonographe sa400 or McCormack DNA-1

If I were buying one I would get the McCarmack as I think it is a considerably newer design; I was a Sonography dealer but that was a long time ago and I can't remember what the sa400 sounded like if I ever had one. Adcom is/was a marketing company and their products varied considerably. I think the 555 was made by three different companies for them for example and they sounded different according to who had made them. The DNA-1 is made here and McCormack is still around; CJ is also but since they are not making SS amps any more they may not have as many parts lying around. YMMV.
