I am running U2 Mini in Roon only mode and I love the sound.
Can I connect my USB drive to U2 in Roon only mode? My Roon core is on an old Sonictransporter, and the drive is currently connected to it. But I suspect SQ may be improved if the drive is connected to U2.
USB drive must be connected to Roon Core. It must not be connected to Lumin hardware (unless you use Lumin app, but that’s not possible in Roon Only mode).
