Stay away from the nad

Same here with a 315bee integrated.  Good sound for the money, but built with components so cheap and assembled so badly that it did not last much longer than a year.  The entire pre-amp was totally shorted, inputs, volume control, etc... in a more than caring environment. 
So for me, never NAD again.  In addition, the new classic line hybrid digital have not been well received by reviewers.
imho, NAD is not going stay one the market much longer.  They have made the wrong choices when it come to quality control and designs. 

NAD has been most troublesome brand since day one .

It's always been my experience in 31yrs of this audio hobby,
That you get mostly what you pay for.
There are exceptions to this though.

NAD / New Audio Disposal

I would disagree with schubert "troublesome brand since day one.'.  I'm with mitch2.  I bought my NAD 3130 in 1984/1985.  Still have it. Used it in multiple systems, and my oldest daughter used it in college and her first year of marriage, and now it's back with me.  Only problem now is some noisy controls.  Will probably have these cleaned.  Great little amp with lasting quality.  Sounds like that's not the case for NAD these days, but I certainly can't fault my 33-yr-old for quality.
