Spotted a second hand NAD c352 in a local trading paper (loot) and bought it for the second system in the study to work with my oldish AE109 and Sony CD player,its sounds better than my old marantz PM 57 which keeps cutting out anyway,but I think the model dates back to 2003 . I read somewhere there where two versions of this amp ,the earlier models not sounding as good and only got 3 star ratings. Then NAD changed some components and lo and behold amp of the year award,Is there a way to tell which is the newer version, this one sounds alright to me.
