If I may interject, an additional 10 watts won't really provide an audiable difference, assuming the same speakers in both cases.

To get a barely audiable increase of 3 decibles, you need to DOUBLE the power. To get roughly twice the precieved loudness, you must multiply the power TEN times. So, those additional 10 watts won't amount to a hill of beans here.

For this to be a good move, there must be other niceties added to that receiver he needs other than those 10 additional watts

If those additional 10 watts are his only reason for looking at this, then I wouldn't waste my money.
