Thanks!! This is really helpful. I can’t explain the issues I was having with the QNAP – I used it only for Roon, and I did no signal processing. And yet after a couple of days all the Roon Controls would get very, very slow. Then when the QNAP was rebooted all would be good again, for a little while.
In any event, I now have my Nucleus+ up and running. Migrating to it was extremely simple, as you’d expect. I’m still storing most of my music on the QNAP, although since I had a 500GB SSD in the QNAP to run the Roon Core I decided to move that drive into the Nucleus+ and stored my most frequently listened to music there. I doubt it makes a difference, but I just wanted to give it a shot.
The Nucleus+ was a little slow at first, but today I installed an additional 8GB of RAM and it’s made a big difference.
And based on everyone’s advice I am continuing to send music to the UltraDAC over the network using the Sooloos protocol – works great!
Thanks everyone for all the help and advice. What a great community!
