My main setup Roon end point is an Allo USBridge Signature with an Allo Revolution DAC into an Hypex Ncore dual mono amp and KEF LS50 speakers. I run ROCK on a dedicated NUC machine.
I have tried now several images on the USBridge Signature and consistently I have been getting the best sound and by a margin (much fuller image, better separation, depth, clarity you name it) when connecting to Roon as a squeezelite client (a functionality not supported officially by Roon). On the same image (be it Gentooplayer, Moodeaudio and now PiCoreplayer - best results with the last two. Tried Dietpi only with the Roonbridge), Squeezelite sounds MUCH better then Roonbridge. I wonder if others had a similar experience?
