mp3? on Sonos? I only use flac from a linked 2Tb NAS or a lossless Deezer service account.
I did one experiment when Deezer went lossless on Sonos. I played a CD through my Mark Levinson No. 37 transport and my Reimyo DAP777 DAC and compared it to the same source being streamed via Deezer lossless through Sonos Connect with Bridge using the same Reimyo DAC-- easy to switch between them-
No audible difference. Some of the remastered CD's on Deezer are actually better than my old originals. This is not hard proof of anything but it suggests that the story is not simple.
