My take on audio is to have subjective impressions with everything, because I fear that if something should be good, but in practice isn't, then I should call it out. For example, I had the poor experience of not liking some of the high-end audiophile software, and I prefer Foobar2000 over most other programs for listening music, not because it sounds better, but i tend to find the others cumbersome. As for Bluetooth, I think that there's a HUGE difference between what can sound best, and what will sound best in most average situations, like in an airport or a gym, where network congestion plays a huge role, which is why I tried to also include how it sounds to the ear, in real life scenarios, not just in theory.
