McCormack Upgrade reviews


I currently have a McCormack DNA-2 DLX and have read about the upgrades Steve will do at SMCaudio. It seems that everyone goes straight to Rev. A. This upgrade costs more than what I want to put into my amp right now as it is my highest quality piece and I think more benefit could be achieved by upgrading other equipment.

My question is this: Can anyone comment on the different revision levels C, B, A, and A+ as to improvements they experienced. I am considering a Rev. C right now but I rarely (if ever) see people commenting about this or the other level upgrades.

I own a DNA-2 LAE (Limited Anniversary Edition) and thoroughly enjoy it's many qualities. Peter Moncrief of Intern'l Audio Review rated the DNA-2 LAE as the top ss state amp back in 1999 if that means anything.

It's my understanding that the DNA-2 Rev. A would offer slight sonic improvements over the LAE version. Better relays (or no relays), etc.. From what I understand the LAE used a certain Toshiba transistors that were extremely fast and Toshiba no longer makes.

Anyway, I have no intention to upgrade the LAE. Instead, I intend to one day purchase a base DNA-2 and send it to Steve McCormack for a Rev A gold upgrade.

Have any of you DNA-2 (any version) guys converted your amp to 230 volts? If so, I'd love to hear about it. I've got the circuit breaker, the romex, and the schematic. Just lacking the guts as I'd hate to blow the thing up.
