The positive comments are welcome news. My information came from a former dealer who is no longer selling the equipment, so it may not have been objective. Over the years, comments on NAD sound quality have been consistently very good. My need was for a receiver and I was not even considering the "Big Box" brands, even in their higher priced categories. Certainly, if I develop any trouble with the C740, it will certainly be reported here. Thanks for the comments.
Any opinions on NAD quality?
As with nearly all listeners, I believe the NAD sound to be just about the tops for the money expended. However, I have heard reports of quality control issues (nothing specific) to the point of being much worse than other manufacturers. Along with a lot of other audio equipment, I own a NAD c 740 receiver, less than a month old, and so far it's working quite well. Still, I wonder what's ahead.
