Beware of NAD M3 Fire Hazard

Hello, 
I agree with contacting NAD as long as they cover the shipping. It looks like a swap of all the boards is the only real fix. If I owned NAD, I would give you credit for a new one and figure out what failed on the old one. Hopefully, the OP would come back to this thread and note they stood behind their product. This would make it Ok for me to buy NAD. If they don’t I would post it here for the world to know. Anything can happen to a piece of electronic. What is most important is do they stand behind their products and was this a one time occurrence. Sorry for the loss. This is why I prefer separates, but I do get this was not your primary system. 

How old is the unit ?
why not call Nad and ask to speak tothe sales and marketing rep . If he cares about the companies reputation 
then he will want to help making things right . This approach makes sense.

I agree... you should have contacted NAD as soon as this happened. If *I* was NAD, I would want to know about this right away so that I could try to make it right. 

I had something similar happen to my Porsche 10 years ago. I had just purchased a 2003 911 Turbo in 2010, it had about 32k miles on it, and was bone-stock; the car was now 7 years old, and well out of warranty. After 2 months of ownership, while accelerating (normally) from a stop light, the engine died. Come to find out, a timing chain had snapped, and the whole engine had to come apart. I made the mistake of reaching out to several different people and shops, including Porsche. Porsche of America got back to me, said they had only ever heard of this happening maybe 4-5 times, and offered to cover the tear-down, diagnosis, and  rebuild of the engine!!! However, I already had it at a independent shop, and they had already torn the engine down (prior to my approval to do so, actually...), so I was out any sort of charity repair work from the manufacturer.

Moral of the story, always talk to the manufacturer FIRST. Worst case scenario, they apologize and send you off to invest in another brand.

Please keep us posted though, I'm very curious about what they will say...

Shaking down a supplier for a 10+ year old+ electronic product, with a history you don't know (not the first owner), that could have experienced surge events, or other events outside the suppliers control, is not cool.
