I have extensive experience with many audio / video streaming apps on a few different hardware systems.
Spotify customer since 2011 (just canceled).
Tidal customer since 2018(volume normalization OFF, or it will mess with your experience.)
Pandora customer since err 2006?
I dont do youtube audio, or amazon, and I dont use Apple but have tried iTunes hires.
I host my own 24bit/192khz/etc hires files, as well as stream & play SACDs on my Marantz.
I rarely use a laptop or PC for any of this, other than hosting.
I use the iFi hip-dac2 for mobile devices and I only stream with USB Audio Player Pro, which is a front-end + engine for streaming apps, local files, etc, and displays details about what sort of file is being played. UAP Pro has very robust user configuration options for tweaking android hires drivers, verifying bit-perfect mode, verifying DAC playback, etc.
For non-mobile, I use the DAC (MMM) in my Marantz SACD 30n to playback files and streams. The built-in HEOS system hosts the streaming apps and accesses network file shares.
I use Klipsch rp-8000f speakers driven by a Marantz model 30 amp.
I use Beyerdynamic dt1990 headphones, my wife’s dt770s, Klipsch x10i earbuds, and soon my MiM Dark Magician IEM (when they arrive.)
I also stream in my car via bluetooth, which has a basic stock stereo/speakers.
Ive spent 10,000s of hours playing music(often the same music) in Spotify, Pandora, etc, and before that Foobar2000 and Winamp for local high bitrate (320k or better) compressed audio, and immediately Tidal is louder and clearer than Spotify - VOLUME NORMALIZATION OFF. Not much difference between Tidal & FLAC files or uncompressed WAV files in loudness or anything else. And this happens on all systems, from lofi to hifi.
Digital volume or hardware volume knobs must be turned down about 10-15% when I play Tidal, vs Spotify, on the car system, headphone amp on the Marantz, hip-dac2 on my mobile devices, and the poor quality DAC (Focusrite 8i6 gen3) on my PC. This is of course just loudness, but on top of loudness my ears can clearly hear a better upper frequency response, tighter overall, and those more “ringing” highs. Im not talking about Tidal MQA/masters, just in general with FLAC
I honestly cannot detect a huge difference between Tidal FLAC and Tidal MQA, and I do understand the state of the controversy with MQA, etc. I also understand how a good number of those ‘Tidal Masters’ are unique recordings - masters - and WILL sound different than other hires versions of the same songs. I dont assume “Tidal Master” means super high fi. I understand it means 1) highest res audio that Tidal can offer and 2) original recordings will sometimes not sound the way you expect, bitrates and sample frequencies aside.
I mainly just use Tidal for FLAC, and it caused me to drop Spotify, on top of the other nonsense with Spotify. Playing Tidal through UAP Pro on android is a good experience. I have not heard Qobuz, and Qobuz just vanished from the list of supported apps inside HEOS…
