I'm not going to argue conjecture. I have over $10,000 in audio equipment and like I already said I play many instruments, so you're not even picking someone good to make generalizations about. Bluetooth codecs are always going to be subpar, but they're probably how most people listen to streaming services most of the time. Anything that is streaming from a PC except Bluetooth is a notable difference.

I just checked the headphones I'm wearing again, they're actually using aptx lossless with a bitrate of 1200kbps. The point is that Deezer offers the same services for less money and higher quality audio streaming.

Apparently, when Spotify does roll out hifi, it will probably be a higher paid tier. Until then, for me, Deezer is the far superior service.
