Suggestions for a streamer only (I have a great DAC)

The obvious solution is an Auralic Aries G2.1 streamer.

Auralic put extended effort into their wifi implementation to make it quieter and more consistent than ethernet. You can use ethernet but the wifi is great and in fact better. It has a 1gb cache into which it streams all inputs and dejitters and reclocks incoming. Additionally, if you are Tidal HiFi oriented, Auralic developed their own proprietary software to process MQA without using the MQA license, and it sounds better. Also the free Auralic Lightning DS library playback app has fewer bugs and better sound than Roon does today.

In my experience, the Auralic Aries G2.1 makes any DAC you connect to it sound better, regardless of price. I use it to feed a Bricasti M21 Platinum.

Roon Nucleus with a Farad super 3 PSU! Forget about the rest!

Bryston BDP v3 is wonderful and way underrated. I have tried some of the others mentioned here but their software was usually slow but almost always buggy. The Bryston solution is not.

I would strongly endorse Aurender either W20 which can be found on the used market for around 10,000 or their newer SE version which I have heard and read is even more superb. This streamer will also accept an external word clock that you can then match to your DAC

Very happy with my Lumin U1 right now. Using Qobuz as my streaming source.
