I know this has been discussed a lot, but to date I cannot find a clear answer. If I'm running Tidal on an iPhone to a bluetooth receiver which supports AAC, is there any point in paying for Tidal Hifi? Tidal premium provides 320 kbps AAC files. Tidal HifI's FLAC's will get converted on my iPhone to AAC and then sent to BT receiver. Will the converted FLACs sound any better than the "unconverted" AACs?
