McCormack SMC Audio Upgrades


I am considering purchasing an older DNA 0.5 or DNA 1 and having it upgraded by Steve McCormack. Is there anyone out there that has had experience with the upgrades and would like to share their thoughts? I am particularly interested in the sonic differences between Rev A and Rev B. I would also like to know if anyone has upgraded their TLC and the effect that it has had. Thanks in advance for the wisdom.

Schroeder; How do you know that the DNA-125 contains all of the Revision A upgrades? What was your source of this information? Thanks. Craig.
Thanks Schroeder, that's some really good info. on McCormack amps, and I've been curious about the new 125 and 225, and how they compare to the older upgraded models-- but haven't heard them. I've been a McCormack amp fan for years. Cheers. Craig.
