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.)

I am also curious about the ARC upgrades, but for the DNA-0.5 or DNA-1.0.

Here are the details I received in an email from Kris at SMCaudio about upgrading a DNA-0.5. Not sure if the ARC-1 and ARC-2 are included in the price of the DNA-125 Platinum upgrade.

The ARC-2 replaces the original IXYS soft recovery diode option on the outputs. Cost is $500.00 and is available on all McCormack amps except the HT-1 & HT-3.

The ARC-1 is a variation of the ARC-2, but is installed on the main AC power supply. Cost is $285 and is available only on the DNA-125 and DNA-225.

Howard,
When yours is scheduled?
My DNA-125 at SMC shop right now for a Platinum + ARC2.
I'll let you know when I get it back (4-5 weeks).
BTW, I've heard DNA-225 with ARC2. Although it still has less than 100 hours brake-in time, it's really something, but I'll let the owner of DNA-225 speak for his amp.
