McCormack Advanced Rectifer Circuitry

I'm on the list to have my DNA-125 Platinum upgraded with the new ARC (both 1 and 2.) :D

Has anyone here already had this done to their McCormack amp? If so, what's your impression?

The more I read and think about this upgrade, the less I think about spending money on other things. So thanks in advance for saving me money in a bizarre sort of way!

Can you provide any more info about this? Now's the first I've heard of it, and the SMc website's link for it is inactive at this time. (Same for the DNA-500 mods -- the link placeholder's been there for a while, but is still not active.)

Where can I read about this upgrade, as you say you've done? Do you mean in the AG forums? Thanks

Anybody with updates to report on this topic? I recently purchased a pair of used DNA-125 Platinum Monos and should receive them tomorrow. These were modified close to three years ago, so they predated the ARC options. Before deciding whether to send them back to SMC for any further work, I'll be comparing them against my stock DNA-500, which should prove interesting. (I also used to own a stock 125 stereo, which I compared against the 500 too, so I'm familiar with the sound of the starting point in this face-off. In that case, unsurprisingly, there was no comparison.)
