Why are you all using your phone as an audio source vs loading the files directly to the cars hd? Streaming vs local files?

I like streaming services. I haven't purchased any music in years

We await your results. Let's be scientific here...

convenience: $9.99/month for unlimited music 'rental' instead of buying. After 30 years I gave up on converting my vinyl collection and have gone streaming. In the car I'm in offline mode. I much prefer selecting playlists of up to 300 songs than buying albums and picking songs.

scientific: tidal is 1,411Kb/s (not 1,144kb/s). so far sounds slightly better but need more comparison between similar albums. and of course the physical cable connection. I'm pleased to see Tidal also supports the skip song function and the progress bar like Spotify.

Appears the spotty progress bar support was a phone issue, since a full reboot I've been 100% solid with the progress bar. As was the interference with a new smart watch - reboot of the phone cleared all issues (likely caused from installing a dozen apps on the phone to support the watch).

My "Scientific" request was looking for your results of cable vs bluetooth using the same input source and bit rates. Thanks

There is hope for us audiophile/snobs in our A3/S3.
Please help me out as this has been bothering me big time. Where can the levels be set? I've looked but cannot find it.

I currently stream music from Spotify (extreme quality) from my Note 4 and the sound quality pisses me off. I've tried plugging in but see no difference over BT. I've put 3K into the stereo to help the sound but local radio stations still blow it away.

You can play Tidal lossless through Audi"s MMI? I have the B&O system. I'll be on that!

You can try... but regardless of source audio the bottlenecks will exist where the quality of the input file is negligible to what comes out of the speakers. There is too much in between the file and your ears for the file to fix the problems bluetooth introduces.

This is mobile audio, flac and lossless files are only going to give you so much benefit, and its probably a wash with placebo.

Wired VS BT on the otherhand, I'd have to say the BT receiver on our cars are not the best for stream quality, to put it kindly.
