Mccormack dna-1 protection problem

As others have rightly noted, give Steve or Patrick a call.  I'm quite confident they will do whatever they can to help you rectify your situation.  Real good guys!

@evilhifi  That sounds right.  I called Steve a few months ago to see what was current with DNA-1 upgrades.  The last mod to my amp was 18 years ago. He said any DNA-1 with a 15+ year old driver board, they would only work on if the work included replacing the driver board because the traces would be starting to crack and fail.

Sent them my amp, got the new driver board along with new inputs, outputs and wiring.  Fantastically sweet, open sound.  Worth every penny.

Good luck with your amp.

@evilhifi  BIG +1 for @gdnrbob  The guys at SMc would probably enjoy talking with someone who knows their way around a piece of gear.  They are good guys and would probably make a deal with you for you to install some upgrades.  Boy is the new driver board worth it!

@evilhifi   Good for you.  Nice that you have the requisite skill set!  and you can always have your unit upgraded by SMc Audio if the desire grabs you.
Enjoy the music!
