Another suggestion of mine is to listen to CDs from the late 80s, when record labels considered 'digital' a mark of quality and actually followed through with the marketing. They tend to be the best, in my opinion - they have good dynamic range which nowadays is usually compressed out of the recordings to maximise loudness, and they had just started using 192kbs bitrates, which I consider to be at the upper level of my hearing ability. No help for new albums, of course, but hopefully those will have FLAC downloads available as some consolation!
As someone who grew up later in the MP3 era (90s), I guess I never knew what "good" audio ever sounded like. I'd love to do a back-to-back comparison of the same song, one in "modern" shitty no-dynamic-range and the other in a higher-fidelity version to see if I can notice any difference at all. Between my consumer equipment and my aging ears, I dunno if I'll be able to at all...?
It seems that my confabulation of 192kbps was also a gross underestimation - apparently, the Sony PCM-1, which was released in 1977, already had a bitrate of 573kbps.
Brothers in Arms was one of the first albums recorded on a Sony 24-track digital tape machine.

I recently bought a pair of Bose QuietComfort Ultra and sent them back because I had nothing but issues with them and they were barely any better than the Anker's when working. Certainly not worth the price difference.
