I have the Bluesound Node2i, then went to the Bryston BDP3. In truth, I never have heard the BDP1. The BDP3 is a significant sonic advance over Bluesound. Beware, however, of Manic Moose, which pretty much everyone hates. The BlueOS makes for a much more pleasant user experience. I now use 3rd party apps with the Bryston, the best being Regelian
