About your comment,
" My personal view, which I shouldn’t share while I’m posing a survey question but I will anyway, is that most of these folks chasing bitrates would do FAR better if they refocused their energy and money on quality speakers and amplification,...suited to the room and setup correctly. With wires!"
I would agree in terms of bit rate generally as Qobuz sounds best to me regardless of whether it is "Hi-Res" or CD quality and Spotify Premium sounds 2nd best (better than Tidal and Amazon "Hi-Fi") But my perspective on equipment is that you can’t hear what’s not there and you can’t unhear distortion/noise by adding better amps and speakers. I’ve found the improvement in sound quality along the dimensions of presence, detail, and coherence in music from moving from WiFi to Ethernet streaming (with WiFi turned off) to be much greater than that from switching between Spotify and Qobuz. Going from an AmazonBasics Cat 6 Ethernet cable to a Supra Cat 8 cable also made a significant difference as did moving to a dedicated streamer from an PC or iPhone output. You can’t reproduce what’s not already there in the signal & you can’t clean up a signal that’s polluted with jitter and analog noise.
I will say that local files (WAV files) sound best to me. Perhaps because they take a shorter signal path before going to the amplifier than streamed files.
I will acknowledge that this is a personal perspective, as I know other listeners care about different characteristics of music than I do. (e.g., ability to play deep bass, extended top end)
