I have a DNA-1 Platinum Ultra upgrade or something like this. Its an end game amp for the series. One thing that really is required with his gear is careful component matching, I've had a lot of trouble pairing up these amps with my preamp due to the very high input gain.
Upgrade McCormack or...
I have a McCormack DNA-1 Deluxe that I've been very happy with for the past two years, but I'd like to see if I can do better within a limited budget. Steve McCormack's folks at SMC will upgrade it for ~$1850 (Gold upgrade), but is there a better amp I can find for less than $3000 used (the approximate value of my amp plus upgrade cost), that might make more sense; any suggestions?
