I would think NAD/Lenbrook would be helpful. I called them to talk about parts for my PSB speakers and they were fantastic. I also called tech support for my Bluesound Node 2 and they had a real live Canadian person on the telephone to help troubleshoot. They solved the problem in minutes with professionalism.
I also have an NAD M51 DAC. It’s been flawless, but maybe a year old at best. It’s quiet, well built and does not seem to be laden with cheaply sourced parts.
The OP’s predicament is frustrating. It’s also either indicative of some really bad luck (as he/she had 3 NADs fail) or a real quality control problem.
My experience in the past 2 years with NAD and Lenbrook has been fantastic though.
