I run my B&W 683s off my Denon 889 (same as 2309). I absolutely love what they do together! I do admit however that i really wish my Denon had pre-outs so i could ad a power amp. (emotiva xpa-3 to be specific).
But the 3310 does have pre-outs so i highly recommend them together. I have been doing a lot of research on upgrading my 889 to something like either the 3311 or 4311...(or Marantz 7005 or Pioneer SC-27/or 37 yada yada!)
Enough about me

... for home theater use (bluray) the 683s paired with the Denon are phenomenal. Once properly calibrated & room treated at least a bit, i have literally listened to many other system that cost more that twice as much that dont touch mine. Take that comment for what it is since i'm sure it comes from a biased viewpiont. But i have had others comment to me the same.
For music i like them but i do understand that i am currently underpowering them so i am not hearing them at their potential. I am satisfied but sometimes still desire a little more... because ive heard more... i.e B&W 802D, Thiels higher end stuff, Magnapans etc.
But for their price point i have never once regretted my purchase.
I hope this helps you in even the least bit! If you have any questions about them directly feel free to ask!
Happy hunting & happy listening!
