Next step into Digital Streaming

Yes, many streaming/server companies allow this type of networking. If you’re happy with Bluesound, you can get a Bluesound Vault and use that in your dungeon to store and serve your files. Your Node can go upstairs and act as an endpoint for that stereo. 

Depending on the type of investment you have in your system, you may consider other audiophile streamers/servers. Aurender for example has its own networking capabilities and performs at a much higher caliber than Bluesound, delivering improvements such as clarity and soundstage size. I am an Aurender dealer that used to own a whole house full of Bluesound gear, so those are the two I have most experience with. That said, there are lots of other options on the marketplace, such as Roon and Roon-enabled devices, etc.

I have been streaming and serving digital for years, and I can tell you that typical NAS or network drive solutions do not deliver the fidelity that an Aurender unit can when serving a file from its internal drive. I cannot fully explain technically why this is the case aside from the local file within the Aurender benefitting from a robust linear power supply, well isolated components, and quality clocking. I’ve built my own audio server with caching memory capabilities, investing thousands into my own Roon core in a fanless chassis with good Farad Super3 linear power supply and I have still found Aurender units to deliver much better quality streaming and local file playback. That server, sans the power supply, is now just my movie and file server, and I won’t doubt Aurender again. Just my two cents.
