Can t compare but bought a D7050 unit, never worked, turns itself of after 2 minutes. NAD warranty is not covering as I moved to another country. NAD has absolutly arrogant and unhelpfull "customer service staff" telling me not to use a screw driver as otherwise the guarantee is void !! No help from local NAD dealer, they first want to see money before they are even willing to look at the unit. Spend more than 700 € with shipping for a piece of crap! NAD -never again, stay away, company policy leaves you with nothing but scrap metal !! They state: Quote -primarily the warranty is based on the fact that with electrical goods there are individual local safety requirements, regulations, conditions and trade practices that need to be met. -unquote. In my case the unit is not working at all, it has nothing to do with local safety requierements etc. But NAD is telling me tough cookies, send the unit back to where you bought it --to my expense as the local dealer isn t interested at all in carring for a customer. Crap ! The finish quality is bad as well: The two knobs (Volume, Select) are made of plastic, wobbeling around on their achsels and the side finish of the unit is made of a rubberish substance which leaves your finger prints on it when touched. All in all : First and last NAD piece I bought.
