Just a heads up on the Node's USB output when using the Node as a Roon Endpoint - there are still issues with the implementation of this from Bluesound's side of things.
On their Support/Community site, they state the Firmware that opened the USB output is still in Beta. I've used the USB out to my DAC, and like many others have had to revert to a digital coax connection for Roon as crackles and pops make listening impossible.
Hopefully this will be fixed with a future Firmware update, but at the moment it's an issue. But just to emphasise, digital coax output to a DAC works absolutely fine with the Node as Roon Endpoint
