I have a Roon Nucleus and have utilized it as a server/streamer. In my opinion, it was decent, very enjoyable, but not great. Together with an Sbooster LPS in place of the stock power supply and a decent USB cable (in my case Curious), I thought it was somewhat better (say a smidge better) than a Node 2i hooked up via coax to the same Chord Qutest DAC. Then in March of this year put a Bricasti M5 in play as my network player and Roon enpoint via Coax to the Qutest, and this took things to a whole other level.
Roon Nucleus as a Streamer
The Roon Nucleus and Nucleus+ have been recommended here as a music streamer hooked up directly to a DAC via USB or i2s. Others advise against this saying it should only be used as a music server with a dedicated music streamer in the loop. What are your thoughts?
