Ditto on the Audible Illusions M3A and double ditto on their terrible service. This should definatly be a factor in your decision. I have had problems with my M3A (nasty noise when turning the volume controls and a loud fuzzy noise in one channel when turning it off). I gave up on AI ever returning my calls concerning this and had some one else fix it. But I have been very happy with the sound. I also bought mine 3 years ago from a dealer who was discontinuing carrying the line and got it new for $1400, an unbeatable deal. If you don't need a phono stage you may want to check out a passive preamp. Reguarding the DNA-1 revisions verses the DNA 225 (the new amp replacing the DNA-1)I was told the $3000, DNA 225 is comparable the B revision which goes for $500.
