I use Spotify, and download all my music in the highest quality. I saw that Spotify is set to release a new tier to their subscription, a HIFI tier, having presumably lossless audio quality. My question is is it worth getting this tier if you stream exclusively over Bluetooth? I do have B&W PX7, so I do have access to higher quality codecs like aptX and aptX HD, but it is still quite a bit less than the 'lossless' audio that is promised to be coming. Will I hear a difference over Bluetooth if I use a higher quality? SHAREit
