Thanks to this thread, I downloaded the Amazon music app. Previously I’d always streamed via Apple, I notice a much better quality with the Amazon HS choices, so thank you for the thread pointing me in that direction. I hope you get it figured out to your satisfaction faction. I also agree that it needs an EQ, was surprised/disappointed it only had basic Bass/Treble adjustments.

I will sometimes purchase and download high-res, high bitrate audio tracks from various sources to listen to on my home system. I really don't think my middle-age ears are capable of hearing most of the added detail.

For streaming, I have subscriptions to Tidal and Spotify. I use Tidal on my home system, via a BlueSound node, where I can perceive some quality difference between Tidal MQA tracks and Spotify's highest format. I can also hear the difference using inexpensive Sony WH-1000XM4 wireless headphones on my computer.

In cars though, I just stream Spotify at its highest quality setting. Because, while I can hear volume differences in between the same song on Tidal and Spotify in cars, I can't really hear any quality difference between the two in cars.

I'm curious to see if that changes w/the Burmester in my incoming Cayenne S. But I doubt it will make much difference except for volume (the same song in Tidal always seems a bit louder than in Spotify). Overall, the Cayenne will just sound more detailed and better regardless of if I use Spotify or Tidal due to the better acoustic environment and more sound deadening in the doors and whatnot.

I suspect that we could spend all the money we want on in-car audio for a 911 and that, due to the poor acoustic environment and the limitations of speaker housings, most of the high-res detail we're paying for is lost. Adding additional sound deadening everywhere probably helps some. People will say otherwise and it's possible I'm wrong.

But I'm reminded of when some engineers set up a blind listening test for some audio industry journalists who promoted outrageously expensive speaker wire. I forget the exact details, but they used some very expensive speaker wire, some inexpensive speaker wire, and a jury-rigged unwound coat hanger.

The results made it clear that, at least over a short distance, nobody could reliably hear the difference between the different speaker wires. The conclusion being that while spending more will provide more reliable production quality, and more insulation from interference over long distance runs, spending $1000s on speaker wire to go 6 feet is largely a complete waste of money.

I love the Burmester in my GTS (hits really hard), but do agree the Bose sound stage in the 9Y0 Cayenne is slightly better. But as others have mentioned, the speaker layout and interior environment makes a huge difference. I don't really think its a fair comparison between the two. The Burmesters is hands down better, but does lack the soundstage primary due to how small the car is

Why would you want to do that if you can plug your phone into car’s usb port (w/BT off)… and still have hands free (through car) calls? Have a BT set of earbuds that u want to take calls from?

If I could choose the balance (discreet signal, high/low pass filter and slope… e.g. the things you can do with your average $150 Kenwood) between the 12 (?) or so odd speakers… I could DRASTICALLY improve the Burmester in the 992.

You are correct that CarPlay will use WiFi for the audio signal. However, it is not a lossless encoding. it's re-encoded to ~256kbps AAC, if I recall correctly. Amazon music shouldn't have any control over how it is output - CarPlay takes over all of the phone's media audio output.

Have you set up Apple Music for hi-res audio? Settings app > Music > Audio Quality. You should be able to set a desired quality for downloads and streams. I've downloaded my entire library with hi-res lossless toggled. If I'm honest, I only notice a slight difference between Apple Music and Spotify's highest quality. It's subtle, and most noticeable at high volumes where I notice the audio is just "cleaner" - less muddied/distorted.

FWIW, using bluetooth or wireless carplay makes this a moot point because both options will re-encode the audio stream with varying degrees of lossiness. I turned off wireless carplay and am now plugging my phone in every time because I want the lossless audio.

@12v Nick might have some solutions for you, if you're looking to throw money at the problem. He's got a Bose upgrade kit that is stellar based on the reviews I've seen here, and probably has the experience to know what the Burmester needs to shine.

I use native Spotify instead of Carplay Spotify because of the graphics. I am curious if there is a difference in sound quality. I have the Burmester.

Wired CarPlay should transfer lossless data. Wireless will not.

L76

Yup. Use the wired connection. Also submitting an official request to Porsche via this post… please upgrade PCM to include following controls over Burmester:

1. Create a “custom” setting in addition to pure/surround etc. Wherein we …

2. have ability to set balance to each individual speaker (high/low pass filters + slope + level input)

3. have ability to apply various digital processing of our choice in that custom setting (Dolby/atmos/stereo/whatever) that is already licensed in the Burmester system

This should be relatively cheap/easy for Porsche. This is a software solution. They already pay a team to build/manage/upgrade/etc PCM. it’s just writing the next release of PCM software and making it available to vehicle owners who have already licensed/use PCM in their cars. No licensing to audio companies that they have not already paid. This is just writing an interface to give the driver more granular control over their system.

… I’d be curious to see what happens if I were able to pare the Burm down to the 2 door speakers and worked with old fashioned 2 channel stereo separation. 🤪😁

cheers,

I heard this some years back. Recently I tried to find a source for the story and couldn't. You happen to have one?

I did a web search “speaker wire coat hanger test” and found a bunch of articles on the subject, most seemingly confirming what I’d read many years back. But I did not find the original article by the group of engineers who conducted the test.

Turning Bluetooth off on my iPhone 15 Pro and going to a wired instead of a wireless connection in CarPlay has been a revelation for me. 2023 Carrera T with Burmester and Apple Music playing lossless songs.

Does the Burmester have a built in DAC?

Patriot

Not aware.

If not, you’re not getting Hi-Rez playback.
