Stay away from the nad

The NAD gear I have owned over the years has been fine.  They do seem to have a checkered past regarding reliability however.  Suspect it relate to little direct control over quality. 

This is an irrational response on more than one level that should be considered with caution. First, the problem is a sample of one. If, for instance, an audio dealer dumped every line of equipment that had one failure there would be nothing to sell or buy. Every product has some failure. Secondly, the $400 quote (very high, especially if they did not do some circuit board level testing) did not come from NAD but an independent agent whose only connection with NAD is that the agency agrees to accept NAD's flat rates to fix in warranty and if probably a high quote. There is nothing exotic about a C356 and the problem is likely minor since it still functions on both channel. For the record, I would send the unit to United Radio in Syracuse, NY, probably the best service agency on the East coast if not the country. They are very reasonable. I have sent them hundred of units to repair.  If you live on the East coast this is where NAD would direct you. John Dorsey  SOUNDSCAPE  Baltimore, MD

I owned an NAD C370 integrated amplifier for nearly 15 years. At times it was worked very hard and for long hours!
Many parties😝 never had a peep out of it. Just recently sold it to upgrade and got a decent price out of it for its age.
Perhaps quality control has dropped off but I loved my NAD!

interesting you say sample of one.  A few years back I was looking at them and a local dealer said they were pretty popular, but decided to drop the line when they kept getting them returned for repairs or failures, definitely not just an N=1.  That wasn't the only dealer that's told me that.

Any dealer that will bad mouth a brand they don't carry or no longer carry is not worth doing business with.  It's something a dealer with integrity just won't do.
