I currently have the Roon Core running on a QNAP TVS-871U-RP with 32GB of RAM. I have a large music collection – 22K albums, 337K tracks, 8.4TB storage – all stored on the QNAP. I thought this system would run the Roon Core well, since the QNAP basically does nothing other than Roon. But it is pretty unreliable and gets very slow over time. I even have the QNAP reboot itself 3 days a week, but still have issues.
Given this, I am considering a Nucleus+, and just use the QNAP for storing the music (unless there is a way to store 8.4TB directly on the Nucleus+).
I also have several Roon network endpoints, but one endpoint I have is a Meridian UltraDAC, which is in the same rack as the QNAP. The UltraDAC powers my primary listening room and connects to the Roon Core on the QNAP over the network using the Sooloos protocol.
I would like to understand the optimal setup – cost is no object – to have the absolute best audio performance. Given this goal, is a Nucleus+ the best choice for the Roon Core? If so, it looks like it is better to send the audio from the Core to the UltraDAC over the network rather than connecting it directly to the Nucleus+ via USB, but I wanted to confirm that is correct, and, if so, I am curious why.
Also – assuming I should continue to send the audio over the network, are there any audio quality issues using the Sooloos protocol built into the UltraDAC, or should I instead connect the UltraDAC to a Roon Ready network player via USB – and if so, any recommendations?
