Roon doesn't even claim it "sounds better". Unless you are using SRC, room correction/eq, hqplayer, etc within Roon than it seems hard to comprehend how it can better.
Roon Vs JRIVER MC 24 sound quality comparison on PC to DAC
I already have a JR MC24 loaded on my PC. I play music from it via the USB to my DAC. I have recently read on TAS that the sound quality of Roon is better than JR and other software. Anyone has any experience of JR Vs ROON only with regards to Sound Quality.I am ok with metadata, etc of JR MC24. Will shift to Roon only if sound quality is better.
