Stay away from the nad

Today I will be listening to my 36 year-old NAD 2150 that sits in my garage year-round, through 80/90 degree summer days and sometimes single-digit winter days, has never needed repair, and still sounds great on a pair of larg'ish outdoor speakers.
I guess they don't make em like they used to.  
I suspect you will really like the Accuphase.  Happy 4th.

I bet you could make one pretty indestructible commode with a single Magico, though(;

Your frustration is understandable.

Personally, I'd send an email to NAD describing in detail the issue you're having. Include your purchase information, model, and serial number. 

Giving the manufacture an opportunity to make an offer is free and who knows? 

Not
Always
Defective

Thanks for sharing your experience. I had considered the M17, but the old tongue in cheek poke at NAD, just always stuck in the back of my mind. I realize that your experience may be a "rare" case, but reading it steers me away even more.
