I have integrated Roon with my BlueSound series-2 system, which connects to various BlueSound components by Ethernet. I have a couple of Pulse 2s, plus a Node 2 and a Power Node 2. The Node 2 connects to an external DAC, which feeds into an amp, which powers floor-standing speakers. The Power Node 2 powers in-wall speakers. Again, the whole system connects by Ethernet, so I am not using wireless technology.
Recently, BlueSound announced its 2i series. While it seems the 2i series might use improved components for speakers, I am concerned mostly with the improvements to the Node and to the Power Node. The Node 2i, which is their streamer without an amp, has new bells and whistles, but they appear to involve mostly wireless technologies, such as aptX HD, WiFi and Bluetooth improvements, and AirPlay 2. (They also mention MQA decoding, but I thought the series 2 already supported it.)
One review of the Node 2i gushes that “[t]he richness across the frequencies is retained, but the soundstage appears further opened and with even more granular detail fed in.” It continues to billow with similar purple prose common to stereo reviews, e.g., “It is in the subtleties of a composition that the Node 2i really thrives, showing its ability to pick out the varying intensities of a fingerpicked guitar, arpeggiated piano line or call-and-answer arrangement that may provide rhythm as much as hold a melody.”
I am far from an audiophile, so please allow me a simple question: if BlueSound series 2 already streams bit perfectly (if that’s a phrase) to one’s external DAC, how could anything in the series 2i improve the sound quality in that setup? (Now, maybe the reviewer was not using an external DAC, but that seems doubtful.)
Perhaps the Node 2i could sound better if one used its internal DAC, or the PowerNode 2i could sound better than the PowerNode 2 because each uses its own internal DAC and different components to feed out an analog signal, but how could the Node 2i sound better when using an external DAC?
For that matter, as long as one is using Roon to run a stereo system to stream digital data to a DAC, how could any bit-perfect streaming device sound better than another bit-perfect streaming device?
