Do you have access to any other brands, Arcam, Primare, Krell, or on a budget Adcom? If you buy from a NAD dealer see if he will let you borrow one of NAD's Master series to try.

I haven't used Kimber but they seem to have a good reputation. I wish I had the answer for you but I'm just not that familiar with different models of NAD. Until maybe a year ago we didn't have any one in my area that even carried them.
