Beware of NAD M3 Fire Hazard

Sorry for your loss.  The picture was truly worth a thousand words.  NAD should give you some help.  They might not replace it, but should offer you a steep discount on a current production model.  Keep us informed.

Dump this unit asap as its pure garbage.Good luck

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.
