Hi, I ran an experiment today and moved my audio system around in the room.
Previously, my Resolution Audio Cantata DAC was connected to an iMac and I ran Roon through the iMac as an endpoint via the network (the Nucleus+ is directly connected to the router). Today, I moved the system and connected the DAC directly to the Nucleus+ via USB. Roon worked - it saw the Cantata - but the volume from my amp was significantly decreased. I had not experienced this in the past when I had the DAC connected directly to the Nucleus+.
Nothing else was changed or done differently. I experimented with the different volume settings in Roon, but none had any impact. I had to turn the amp up to about 50% volume to begin to start hearing the music.
I then put the system back in the original location with the Cantata DAC reconnected to the iMac. The volume was back to normal, issue resolved.
Are there other volume settings for when connected to the Nucleus+ via USB? Is USB out from the Nucleus+ typically lower than other endpoints?
Thanks for your help.
