Theoretical maximum sound quality for Bose

[Dilpo]

Hi Everyone,

Somewhat new Taycan owner here. I found a lot of discussion on the forum about our love/hate -relationship for Bose but started wondering:
At which point increasing the audio quality of the source becomes redundant because of either the wireless transfer of the music or some other Taycan/Bose -related reason?

As an example, CarPlay would compresss the files when using wireless but what would be the max bitrate of the compression320kbps?

if using wired CarPlay would this change? What about USB and PCM native music player?

I know at some point you cant hear the difference anymore but wondering whats the theoretical best quality I should aim for.

Thanks.

You can play Apple Lossless via CarPlay wired USB connection from an iPhone. The PCM DAC does appreciate the higher source material – I feel more so on the BOSE than the Burmeister (having had both in my Taycan's)

I’ve found that FLAC files from a USB source are significantly better. I have turned off Surround and turned on Linear and just fiddle with the treble and bass to suit the genre.

I found Spotify via wireless CarPlay to be not to my liking.

Native Spotify somewhere in between.

Not sure what aspect of the performance causes it but I find playing from a thumb drive plugged into the USB port sounds best.

It is a mystery to me why because I have found at home in a dedicated listening room using kit costing more than the Taycan and a background noise level of ~28dB the difference between 16/44 and 256kb/s mp4 is too small to complain about (there is a bigger difference between recordings than file types IME by a considerable margin).

Mind you I don’t consider a car to be much good for music listening whatever the system and file type.
