Purchasing barely used NAD gear

@jl35 that seems to be the consensus from what I've been reading.  I would be using the amp to drive some DQ 10's. I know the amp has the dynamic power. I'd be worried the amp would probably go toasted since the 10's are not an easy load for many amps.  25 years is a long rest LoL

notoriously unreliable

Hardly.

My 2005-2010 NAD gear had horrible reliability, acknowledged by NAD Service. My 1980’s NAD were quite durable. I think their reliability is by era’s. Not sure about current stuff but I’m hesitant to purchase again 

     Keep in mind: there are numerous aluminum electrolytic capacitors throughout the circuits of all of those NAD components.   NOT just in the power amp's power supply.

     All are subject to electrolyte drying out (after a couple decades, used or not) and causing diminished performance, if not outright failure.

      The same holds true of virtually any vintage audio gear that employs, "wet" electrolytics.

Yes, given the age of the components in question, and with interest in NAD,  I would think a better option would be to purchase a ~5 year old used NAD C326BEE or C356BEE for around $300. I purchased recently a C356BEE off Audiogon for $290 including shipping.

I have owned both these models without issue. The C356BEE mentioned above is my 2nd one.
