I'm relatively sure that answer would be a yes, however at what cost and complexity beyond your current BlueOS setup?
Further, it becomes a multifaceted question involving the combination of both playback software and hardware (eg. Roon, or perhaps Audirvana+ for instance on the software side) and then various different hardware options (the "streamer" or what some might also call a "server").
While that's a complicated question in general and certainly involves end-user preference in terms of complexity and ease of use (or lack thereof), for you in particular it does narrow back down pretty quickly based on your speaker/amp choice.
I believe it's safe to say that speaker/amp part isn't changing, although I'm guessing there might someday be an upgrade available that could involve a different digital module. Pat had already alluded to 24/192 capable boards, and I had asked out loud at one point about different connection options for those boards but don't recall any response. I had also asked at one point what the current board's input options are but also don't recall any response.
So maybe an initial look at this within the context of the current set-up needs to define the input options on your active speakers. What are the inputs? SPDIF coax, and analog RCA that gets digitized at 24/96?
What about AES/EBU balanced via XLR? How about Ethernet, and if so, which protocol? AES67, Ravenna, Dante? Which digital inputs the speakers currently have and/or may someday have will largely dictate what streamer options to consider.
I'd say in the "right here and now" realm an interesting option might involve trying to supercharge the SPDIF output of the Node 2.
I have heard Sonos and Squeezebox products that had modified SPDIF implementations (power supply and clock) and they are clearly better than the stock offering. While I don't think I've ever heard of any Bluesound SPDIF modification offerings, they may exist, or you might even try that with an add-on box such as the
Wyred4Sound Remedy, or the
M2TECH hiFace Evo Two.
But an extra box, cable, and power supply, not to mention the added cost, does fly in the face of the current setup's simplicity. Dare I suggest you won't be considering any of that? If so, you are likely then waiting for the potential of swapping the digital input board in your active speakers for something with Ethernet, USB, or perhaps I²S, which would open up other options on the streamer side.
Audio over IP (AoIP) does appear to be the wave of the future there. But like with so many things in audio, getting the industry as a whole (or even any great majority of it) to agree on one standard is probably a pie in the sky, and that's very frustrating for confused consumers who rightfully fear buying the wrong thing and thus risk future incompatibility or rapid obsolescence. But a direct network connection to the speaker via Ethernet (bypassing the need for any SPDIF, USB, etc...) is likely ideal, maybe a future digital input board for your actives using Ravenna or some other AES67 compliant solution would be that end game.
Until then, maybe try supercharging the SPDIF of Bluesound, or consider other more complex/less tidy software/hardware combos that offer better SPDIF or even AES/EBU output (assuming the speakers actually have that input).
Bluesound is of course quite nice, but it is certainly designed and built to a price point, not entirely unlike that of Sonos (or once upon a time Squeezebox). It can be bettered, but at what cost and complexity do you throw in the towel?
I've read a few threads here of late where there is a stated level of intolerance for almost anything beyond just sitting down and listening to music with as little fuss as possible. That seems to increasingly be the rule of the day. Thats perfectly OK if it's what will make one happy, hobbies are supposed to be fun, and no one need feel that a hobby (or indeed just the mere act of listening to music) be an arduous or annoying thing. But it also likely means off-the-shelf "finished" digital solutions like Bluesound, and whatever costs, compromises, and limitations they inevitably entail.
