But you just said it yourself. The audio system leaves a lot to be desired, whereas I have a system on my phone that will provide an analog signal that will sound better. In the end all audio is analog and nothing I've read yet on this forum or anywhere else tells me that M3 has anything above mediocre digital audio processing. I would prefer to bypass all of its digital and plug directly into the analog. The BT is not high quality audio, the streaming services they provide are not high quality, but I do have a high quality device with no way of connecting it. If Tesla had a hi-res service I'd be fine with that too, but they don't and that is just ridiculous in this day. I saw on another thread that Tidal may be available soon, and that would be an improvement, except I cancelled Tidal and opted for Qobuz instead.
And Sirius/XM is also a joke with sound quality. I've rented many cars with it and I always just turn it off. But I guess the M3 doesn't have that either in any case.
This is a huge step back from where we are with streaming today. I can stream 24/192 files to my 20 year old kitchen system with a Raspberry Pi but can't stream it to a car that is supposed to be revolutionary in its design?
What I have isn't big either, it fits in my pocket with my phone, just a USB adapter for the Lightning port and a USB thumb drive sized DAC.
If you have any decent sound system at home with a separate DAC (now I'm getting above 95% of the people out there) give Qobuz a try with their free trial and desktop software.
