Streamer's without built in DAC options?

Bryston BDP with Soundirok app, works like a charm.

The simplest option would be to continue to leverage your Roon Nucleus to run Roon Core and storing your music on the Roon Core and/or a NAS device.  These devices are both connected to your home network and can be in a different room than your system.  Then you add a Roon compatible network player like the Simaudio Moon MiND2 or DCS Network Bridge and connect it to your Tambaqui DAC via your preferred connection (USB, S/PDIF, AES/EBU).

You already have storage and a computer to run Roon Core handled with your Nucleus so you don’t need a server that handles file storage or streaming through Tidal, Quobuz or other streaming software.  Brands like Innuos are fantastic servers but you’d be paying for storage and other features that you already have with your Roon Core.  

Hey Tom @tom_hankins : do you already have the Mola Mola Tambaqui? If so, congrats! Do you know that the Tambaqui has a streamer built in? A network bridge. Connect it to your Router / Switch via Ethernet, and you are good to go. The Nucleus will continue to be the Roon Core (the server).

Basically, with the Tambaqui you do NOT need a separate streamer. It has a streamer built in:  https://roonlabs.com/partners/molamola

For what it's worth, the USA distributer of the Tambaqui told me that the USB is a better connection than Ethernet on this DAC (and also the Makua preamp with internal DAC). He demos using the Aurelic streamer, which he also sells.
