Thanks for the replies. I was not very clear, earlier. I am currently using the network connection to the Bartok and running a server that I also use for home theater and other amusements -. Hence JRiver.
However, when I tried to play DSD files in the same configuration it would not work unless I used the ASIO driver and USB. I am not crazy about USB for PCM, so I can’t just leave that selected. Switching between the network and USB configurations is a PITA. I was hoping there is a way to do this, within JRiver, and without having to futz about with Mosaic to switch to USB on IOS and then driver selection on the PC. Small things but each menu selection is annoying especially because you have to reverse them every time you want to change activities. I like easy.
I guess you can’t get there from here. I will have to use Mosaic for music playing if I want to enlarge my DSD library. I have loaded up MinimServer (thanks @PAR) and that works seamlessly (with Mosaic) for PCM and DSD. Sounds good, but I have not found the difference from networked JRiver to be massive, at least not so far. I’ll have to try removing the 1000 horse power PC and running MiniServer from the Synology NAS to see if that makes an audible difference. Every setup is different and it’s way too early to tell what affects sound quality here.
Running Mosaic is not all good. I miss my big screen to navigate about with, check disk info, adjust tags, etc. Maybe it’s time for a dedicated music server.
Don’t get me started on Roon, Audirvana and others. When I find one that respects my messy file tagging (JRiver does, sort of) I’ll use it. Given that I don’t stream online, there is no compelling reason to fix my tags and move to another player.
