Ultrarendu DLNA/Upnp Streaming software

[Mike Rubin]

I use JRiver on my computer to play from my Synology NAS to my rendus.  I control it with Jremote on iPad and either Eos (no longer available at GooglePlay but available as a sideload on the web) or HiFi Cast on Android.  JRiver costs a few bucks (just a fraction of Roon’s price, though) but I really like that it’s stable, will play almost any file without transcoding, and is genuinely terrific for collection and metadata management.  The only downside is that your computer needs to be running at all times to use it.  
 

If you need to bypass the computer because you don’t want your computer on all the time, I like LMS on Synology devices better than Synology’s media server and MinimServer.

The dac is a valve one so certainly not recommended to run it all the time.

In my experience, as well, it's not a good idea to turn the DAC on and off while the Rendu is running.  If you have to turn off the DAC when not in use, you should turn off the Rendu as well.  When you want to listen, restart the DAC first, and only then turn on the Rendu.  Let the Rendu come online and, once that's complete and you can access the OS, check the DAC Diagnostics in Apps to make sure there was a proper handshake.  Try to play music only when you are sure from the DAC Diagnostics that the Rendu actually sees the DAC.
