I'm guessing (and hoping!) that the newer digital/streaming solutions from Bryston will incorporate support for multiple different streaming services (Tidal, Qobuz, Amazon Music, Roon, Spotify...Spotify Connect?).
I do think local storage music playback of your own music has gone down rapidly. I've been collecting and storing my own music for 20+ years but last 2-3 years I've slowly stopped altogether when I added Amazon Music for lossless playback. With cell phone plans offering good data, phones having big storage space for offline playback and of course home internet being more than fast enough, there isn't really a bandwidth, cost, or storage bottleneck like there has been in the past.
The biggest issue remains which devices (or their combinations) work with what streaming services. Tidal and Qobuz are usually always available with most devices or services (Roon, Audirvana, even BDP). However, Spotify, Aople Music, and Amazon aren't always available.
Spotify - still no lossless, but best playlists/suggestions usually. Also, they don't allow other services to use their music without also accompanying their full product. Biggest library amongst them all. All the niche stuff.
Amazon - best pricing on a yearly bundle (but not always available)
Apple Music - terrible desktop experience. Good on iOS I guess. Haven't tried it in awhile
Tidal - I think MQA is sorted out finally, so might check up on it again.
Qobuz - maybe slightly pricier last time I checked. Library not as deep.
I'd like to see more integration of these streaming services with Bryston BDP (or whatever comes after) going forward. Spotify Connect in particular I've been waiting 10+ years and it never came to BDP. I remember Cambridge CXN's came out around that time and it had Spotify Connect. Nearly went for the CXN at that time due to it, but held on to Bryston for local music and possible sound advantage. If I was making that decision today, I'd 100% priorities the availability of streaming services.
