That said, switching between Spotify and Tidal on the same track, I hear a pretty big difference. The lossless music has a depth that just isn't there on the compressed streams

It's fun to think that I might be able to distinguish between uncompressed audio and 320kbps MP3. I didn't think it was possible. I had a hearing test recently, and they did say that I have better than average hearing. But yeah it was probably just random.
I just did this test and got the first two right: https://www.theverge.com/2017/4/5/15168340/lossless-audio-mu...
The third one was really tricky so I had to guess. But the first two were a really clear difference. Uncompressed kind of sounds "fuller" and sharper, and MP3 is a bit flatter. It's a tiny difference but I think I can hear it.
The first sample surprised me on how much of a difference it was, on the 2nd I was wrong, on the 3rd completely lost, but I guess that's by design.
The 128kbps was of course very easy to pick out.
I'm of the opinion that 320 vs lossless is meaningless enough to not really bother, but I know for some tracks it was trivial for me to tell the different. Mostly it was the very complex/atmospheric tracks, Mind In A Box being a good example, where 320 lost a notable amount of quality. Probably others like Ne Obliviscaris as well.
The biggest problem with Spotify is that not all of their library is available at 320kbps.
Spotify uses 3 quality ratings for streaming, all in the Ogg Vorbis format.
• ~96 kbps • Normal quality on mobile.
• ~160 kbps • Desktop and web player standard quality. • High quality on mobile.
• ~320 kbps (only available to Premium subscribers) • Desktop high quality. • Extreme quality on mobile.
The thing that gives it away for me is the extreme highs and lows, both are clipped when compressed usually. I should note, I wasn’t picking which “sounded better”, but rather which “sounded uncompressed”. Several of the tracks sounded better at 320k than they did uncompressed to me. Despite being rather close to 40, I am still able to easily hear sounds well over 20kHz.
The difference is usually very, very subtle (my description for it is "soundstage differences", like slight differences in audio imaging) and if you are in the situation you are 99% of the time where you are not in a critical listening environment, you probably won't be able to even hear this. But if you are absolutely gung-ho about preserving the full spectrum of the recording, MP3 won't work. It's not an archival format by design.
At least with 320mp3s I could only get it right with certain songs and not too consistently. I'd say my room treatment has a far bigger impact.
(but regarding hardware I'm totally with you and haven't found the source of my rather high noise floor either)
