I also have an A I M3A with a McCormack DNA-1 Deluxe as Kleiman421 has and they match up very well.I had a Bryston 3BST previously with the M3A and while it matched nicely ,in my particular system the DNA-1 Deluxe was a little smoother in the highs,and this was also with a tube dac.If you decide to go with a used Bryston and you decided to sell,you will get your money back easily due to their incredible transferable warranty.
