I would think that volume matching would be important: Streaming services may not play at the same level so the louder one will sound better to most people. I tried comparing Tidal to my Hard Drive with the files ripped to the AIFF format(full CD quality) and discovered that Tidal was louder but did not sound better once I did the volume match.
One should keep in mind that the two services could be using a different master which could be a multi-generational source:
Also, 1 demo from Van Halen, not known for audiophile recordings, is not a good barometer. I would think 5 to 10 demos across different genres of music would be more accurate.
I don't use either of the services. My friend was over with his Tidal app and I decided to compare and decided to pass in favor of my hard drive.
