Stay away from the nad

Sorry for typo. "advice". Yes, I contacted nad and the first question was "is the unit still in warranty". When I said no I've got the answer "Sorry for the trouble". Any further conversation with them was over.

It sounds like you didn't politely insist on speaking with a manager.  It sounds like you haven't pursued the matter, but with a budget of over $4000 for a replacement, you won't miss the Nad.

 I had Denon replace a remote out of warranty.  I've had Paradigm replace a tweeter out of warranty.  I've had Nissan repair my Altima out of warranty.  All free.   I guess perhaps it's a skill one has to develop.

Just look at how many NAD products are sold on here alone as 'Factory Refurbished'...... Where there's smoke.........

my own experience matches most of the above posters--the pre-1990 nad stuff has been durable and reliable, while almost all of my post-1990 nad gear was problematic (though in fairness it sounded good when it was working).

The Nad PE stuff from the 80's apparently had issues too.  I still contend that the current integrated amps( or the ones just being retired for the new digital amps) are pretty rock solid.  Yeah there's failures.  Obviously Nad is good to replace them, refurbish and sell with full warranty.  What's the percentage of failures, that's the big question.
