To preface, I watch 95% of everything on my phone (Note 10) and use audio from TV/monitor only, the baseline is as basic as can be. Concepts like Delby Atmos and surround sound is completely wasted on my basic ass. I do have a UE Megaboom 3 and a pair of Sony WF-1000XM4 if that matters at all.
Services like Tidal promises an elevated audio experience, and I've no idea what on earth that means, curious to sign up for a trial. What should I listen to, or am I just going to go "ooooh I get it now, this is the best thing since slice toast"?
If it means anything. Standards in digital audio have gone through the roof so what the "average dumb consumer" get's these days with a decent pair of bluetooth headphones is more than good enough.
e.g. DAC's got small and cheap and even tiny ones in Bluetooth headphones or Apple's USB-C to 3.5mm dongle measure transparent and offer what 95% of people will require for their gear. Bluetooth codec's (the better ones, just avoid SBC) and in the past "MP3 compression" are resource efficient and compression errors are not audible to majority of consumers.
The only real benefit one would experience from uncompressed audio (such as what Premium streaming offers) is if you have above average hearing and can hear above 16kHz or so. Usually that top end of the frequency response is lost to compression (everything above 15kHz is cut off). But do yourself a test with wired headphones and listen to a frequency sweep from 20Hz to 20kHz, most people's hearing will stop around 15kHz. I have tested it and I think I stopped hearing anything before 15kHz, more like 14kHz.
If you can hear above this range you will experience some extra "clarity" but there are some people who can hear above this range still say the difference isn't that great.
That 5% who claim they can hear a difference or who know enough to be confident they are getting their money's worth are going to be spending 1000's of dollars over the years chasing a tiny perceived improvement. Do you want to be one of them? Not me, I strongly believe in diminishing returns (the bigger the next jump in price, the smaller the improvement) and the value for money is just not there.
Edit: Also a tip. If you are listening by yourself like most do, comparing new vs new. Headphones are better value than a speaker setup.
