Well, resale would be better on the c162 if you're going to eventually sell it. I think the sound would be better on the upgrade. NAD is ok for what it is but I had the C162 and wasn't all that impressed especially after what what's been written about it. It had an average sound IMO. Basically just a little step up from the stuff you see in Best Buy. Unfortunately, I guess because of the reasons they're made in China now, NAD has a low quality feel to the controls and cabinet as well.
