I cannot find anywhere on the Bluesound if it upconverts everything to 44.1 or not.@theo ,
Bluesound Node does not upsample or down convert. It natively streams a signal from 16/44.1 up to 24/192.
Check the settings parameters in the BluOs app to see if you can receive HiRes. I honestly can’t remember where this is located. Try Google.
Edit...
I think you need to select select the streaming service and login again. Then you will have access to hires; as long as your Dac samples hires files.
