Good plan. Once you get a new streamer in place you will be able to hear your system better, including the DAC, and decide on a path forward. I should add, don't skimp on digital cables, and plan for it in your budget. I know it should not make any difference, but it does. Good luck and keep us posted.
Is my Sonos 1 Connect the weak link?
I have Roon resident on my Synology NAS. It is wired to my Synology Wifi Router ( no way to run a wired connection, but solid wifi signals). The signal goes to my Sonos Connect which is connected to my Brysten BDA 1 Conveyor. This then goes wired to my Rogue Audio Magnum III. Speakers are Linn Magic. I have all my CD collection on my NAS so Roon can access Internet or resident music.
I have a NAS transport for my CD collection that goesto the Bryston and it seems a bit better than streaming through Sonos. And, of course, my Thorens turntable direct to the Rouge is killer.
How do I improve streaming?
