Can you really tell the difference between CD-res TIDAL tracks and TIDAL MQA Masters ones streamed & played in your car (especially when driving)? Otherwise, you could save yourself at least 1/3 of your data!
MQA is lossy, not lossless.
Even if you could compare a lossy format with a lossless one, that statement doesn't even hold up. Some of the bits per sample of the audio signal are used for MQA encoding/info and contain no playable audio data - so decoding a 24 bit/44.1kHz MQA source/distribution file (as supplied by TIDAL's online server) to the MQA Core signal (aka 'first unfold') at 24 bit/88.2kHz is actually roughly equivalent to a normal lossless 17 bit/88.2kHz audio signal. If you FLAC compress a 17 bit/88.2kHz file compared to FLAC compressing a 24 bit/44.1kHz file you'll get roughly the same size, so no saving at all!
Not sure if you've misunderstood what you've read or if what you've read is itself misinformation - a link would be most useful.
Although not a great shocker, just with my stock speakers in my car, Spotify VS Tidal is not even close on most tracks.I can definitely hear a difference in my car while driving between Qobuz and Tidal on the same tracks, but have not tried differentiating between Tidal's various levels of quality.
But then, I do have a car audio system Bill Gates finds indulgent, so take that into consideration as well.
FYI, listened to Qobuz on the drive in this morning. Damn, I literally didn't know streaming could sound this good. And I'm on T-Mobile, unlimited data. Bring on the bandwidth!
As for Tidal Vs Tidal Masters I have yet to try. However, there are examples of them sounding COMPLETELY different. Wish I made note of it, but when Masters was first released and discussed on here, someone pointed out a certain album that sounded like it was a completely different recording.
With the right system, listening to music in the car can be just as revealing as a home system. It might sound "better" but it doesn't mean you cannot compare different sound quality and not be able to tell, especially if you have say a RR Phantom which is damn near silent inside while driving.
