No file conversion is turned on in Roon. This did not happen on Jriver.
Just for the record, JRiver can absolutely transcribe to WAV files. I use the Bridge II and have JRiver set up to transcribe. I can see the Wav on the DS display from my listening position. All my files are FLAC with a 5 compression, ripped using dbpoweramp.
I expected to see that the file being played was the same file type, bit rate, sample rate, etc. as what the file is saved as. When it wasn’t, it made me wonder if the file was being converted without my permission.
Fyi, Roon sounds better than JRiver. Roon sounds more open and richer.
I may try transcoding to .wav on JRiver to see if it can catch up to Roon.
