I have Bluesound products, but not the Powernode. They sound ok, probably not much more you can do at the price point. I heard the Yamaha at a dealer, not in my system, but sound wise I thought it bested the Node2 when the latter was played through the former.

This subject has probably been beaten to death... I will keep this very simple - I have a pair of passive bookshelf speakers and a room. What do you like/hate/love about of these 5 options? What other options should be considered?
Sonos Connect Amp $200 (eBay used)
Yamaha R-N303 $300
Sonos Amp $649
Bluesound Powernode 2i $900
NAD C368 w/blueos $1400
I feel like $200 Sonos is the easy answer.
