Some of the NAD's integrated amps have been known for punching above their weight.
IMO, I think NAD 352 and C325BEE are probably their best products. I have listened to the cheaper line 315 and was pretty impressive with that one too.
Your 326BEE is probably an improved version of the 325BEE and if that is the case then you have a decent product that can outperform Cambridge Audio, Arcam, Rotel and last for a decade.
Congrats!!!
