@artemus_5 I'm not familiar with the Yamaha unit you mentioned. How's the interface? One of the Bluesound's best features is its app. Keep that in mind when making your decision.
As to your question about "better 1's and 0's", I've yet to see a definitive answer about that. What I can tell you is that I went from a Bluesound Node 2 paired with an Auralic Vega DAC (which was $3500 when new) to a TEAC NT-505 streamer/DAC and it sounds better than the Node 2 / Vega combo did.
I also tried my Node 2 with a Mytek Liberty DAC and the DAC in my Sony TA-ZH1ES headphone amp (which is very good). They all improved the sound of the Node 2, but none of them sounded as good as the TEAC all-in-one device.
My thinking is that the streamer does matter, as it seems everything matters in the signal chain, but no way I can prove that. I have no way of testing the streamer in the NT-505 with an external DAC.
