If he can live without a remote try a $329 Parasound Zamp v.3. It has little volume pots on the back or you can go with a $135 Luminous Audio passive volume control.
I only suggest this as sound is silly-good for the price and a big step up in clarity and naturalness compared to NAD or Cambridge. Also with separate pre and power amp you can change things around in the future if you are so inclined.
