Belles Vs Emotiva

I was wondering what the forum’s opinion on the Belles 350a reference, (if I’m not mistaken anywhere from the $1700 to $2300 ish range used) or the Emotiva XP-A gen 3 at about $1099 new. Both amps seem to have decent reviews, and similar specs from what I can find. What do you get for the extra money with the Belles besides a higher damping factor?
