fwiw, i also went back to spotify after a month of tidal. like ghosthouse, at lower volume, casual listening (which is generally my office mode) i didn't hear a big difference. for more critical listening through good headphones, the difference was more significant, mostly in the sense of tidal being more spacious, with more precise instrument placement; tidal also reproduced drums and acoustic instruments a little more naturally. not a vhs-to-dvd improvement, but an improvement nonetheless.
the real dealkiller for me though, was the frequent buffering and pauses, esp. on the mobile app; spotify has been consistently more seamless. spotify also has the deeper catalog, altho tidal's is certainly respectable. i did prefer tidal's interface, which is clearer and more intuitive; i was generally indifferent to tidal's "curated playlists," which were no better or worse than spotify's.
