I can't speak for the 3808 but I can for their 1906. Mine runs a pair of 8 Ohm M3's and will say Denon's performance is solid. If Denon's higher end works just as well, it's a good choice. Not sure if you've made your decision, but I'll also throw is HK's 645 (my brother owns one). Decent amp tech...that never tires. He also runs M3's.
