Play hi-res audio files.

As a new Macan owner I was surprised to learn that despite the specifications claimed by Porsche in its manual, that the PCM 3.x would play and order WAV files , that it would not order them into the file structure that Porsche claim (artist/album/track). This rendered the fact that it would play files useless for practical purposes.

Note only 41.6MHz 16 and 24 bit plus 48MHz 16 bit WAV files would play in my testing.


Without wanting to open up a debate about the need for higher res files versus low quality MP3 etc files, there are audiophiles that can hear and appreciate the significant differences that do exist between lossless and compressed file types in a vehicle environment.


To discover after purchase that Porsche's claims are false and misleading was a major disappointment (and also contrary to this country's consumer law).


I was unable to find anything on the forums and other searches where anyone had solved the issue, so if there is something around already, you will now have 2 versions!

The service department at the local (company owned) Porsche dealer validated my concerns – PCM 3.x (and I am told but have not tested PCM 4.x) will not play and order WAV files either by USB, Jukebox or iPod reliably and consistently.
It is sometimes possible to have one or two artist/album/tracks work, but not much more than that. I suspect this is due to ID3 tags not being supported by the WAV format.
I have now spent many hours researching and testing and learned how to play high res files - and like many things it is a quite simple solution. So for those other frustrated souls....

1. Convert as necessary the files you require into AIFF/AIF file type. This is best done using a converter that has a tag editor such as Media Center so that you can ensure that all fields are correctly populated.
(AIFF/AIF is an uncompressed file type like WAV, but with ID3 tag support).

2. Using iOS 11.2.2 it is possible to play up to 192kHz 24bit files. I have not tested higher rates or bit depths, as I have not found higher hi-res files generally available as yet, (plus my home DAC will only play to this level).

3. Import the files by drag and drop from MC into iTunes.

4. I found that some album art would not transfer over for some reason, but that is easily solved within iTunes by drag and drop. This was very few albums.

5. Connect to the PCM via USB and go for it.

Note that the AIFF files will not play direct via USB or load onto Jukebox as the file type is not recognised – it must be done via an iPod device. I use my iPhone 7 plus.

There are lightning splitters and external drives available but I have not tested any as yet, so getting substantial additional storage whilst still charging should be easy.


Hope this helps a few other frustrated audiophiles out there.

Audiophile quality sound in a Macan.



Update for the audiophiles out there:

Having now solved the issue of the PCM not handling uncompressed files it was time to start on the hardware.
My car had the standard audio system as I was not happy with Burmester.
The first step was to replace the front and rear door speakers with some quality Focal Flax units as the standard Porsche speakers were really poor quality.


FRONT: Focal Expert PS 165F3 - 3 way
REAR: Focal Expert PS 165FX - 2 way
Both were installed with additional sound deadening.

Sound was certainly improved, but not where I wanted it to be. Working on the principle that Porsche would likely use the same head unit for each of the three audio specs in order to reduce SKUs and streamline manufacturing - and therefore would have used high quality DAC(s) that the Burmester would need to produce anything reasonable (big call but seems to be correct at least as far as the DACs are concerned) - the amps were then the next focus:

Installed an Audison Prima 8.9BIT to look after the OEM speaker configuration.
Installed an Audison AP1D amp to drive the yet to be installed sub.
Both amps were located in the OEM amp location back to back.

A custom box and Audison DVC 10 inch sub which is a shallow mount speaker was installed in the spare wheel well.

The system was tuned using the Audison BIT Tune Software to suit. PCM Sound remains functional.


Once tuned up I tested the system against my Astell and Kern AK240 connected to AUX with an Audioquest cable and the differences were absolutely marginal to my ear other than the car system being a bit brighter – something that can of course be tuned out.
This is an outstanding result that I felt I should share with the other audiophiles out there that are frustrated by poor quality sound in their Macan.

The end result is a sound that is quite a lot better then Burmester and massively better than Bose (albeit at a higher cost over here):


Complete system cost was AUD$3,500 versus Bose at AUD$2,650 and Burmester at AUD$11,590.


Sorry guys but I cant seem to get the image uploads happening. If anyone wants them just PM me.


Hope this helps others frustrated with the poor sound quality in the Macan.

I know it's an old thread, but still relevant.

I decided to load WAVs onto a tiny USB pendrive. I refuse to have my iPhone overcharge all the time. Besides, people who tell me to use mp3 because I can't hear the difference from lossless are the same people who tell me I can't see the tiny airplane up in the sky while I can.

I wish there was a way for someone to add the FLAC codec. As the name suggests it... FREE Lossless Audio Codec, so it's not something Porsche can't implement. Unless it really needs so much decoding power that the PCM can't pull it off (which I tend to doubt). The only other thing I could think of is properly mapping the file tags.

Isn't there anyone with programming skills that can do some magic on these units?

As a test, I ripped a CD into FLAC format and at first because I was not connected to the internet it ripped the CD but the ID tags did not appear. So I deleted and connected to internet and then re-ripped CD onto SD card and tested in car and it worked fine. Even appends FLAC to the end of each song title. I however have volume issue between sat/radio and the media volume output. The media volume is like at a third of the volume output level than that of the satellite/radio.

For those who are looking for options on a better sounding Bose sound system (who could not justify $5000 for the Burmester), before you spend time and money replacing the amps and speakers on your car, you may want to consider upgrading the "source" of your music and consider purchasing a portable high resolution audio player such as the Astell & Kern Norma SR25 MK II ($749.00).

I bought a SR25 several months ago while waiting for my 2022 Macan S, which recently arrived. The SR25 holds a micro SD card onto which you download high resolution (FLAC) music from websites such a HDTracks onto your personal computer. You then transfer the micro SD card from your computer to the SR25. You will need a USB-C to USB-C cable to connect from the bottom of the SR25 to the USB-C plug in the center console of your car. Once plugged in, it may take a minute for the PCM to recognize the USB connection (make sure to turn the volume DOWN). When it does, your music will be shown on the the PCM screen just like apple carplay. I compared Baba O'Riley on my iPhone XS (Apple Music download) connected via bluetooth to the SR 25 and noticed a SUBSTANTIAL improvement in the volume (loudness), fullness, richness, and quality (spaciousness) of the higher resolution SR25 vs. the compressed apple music.
Having come from the Lexicon sound system in a 2012 Genesis, I think the Bose system (on the 2022 Macan) sounds very good for listening to music on Sirius/XM, but for those of us who are used to listening to their favorite CD while taking long road trips, etc., a high resolution audio player can provide you with great sounding music on demand. I know there are other sources of high resolution such as Tidal and Qobuz (at a monthly fee) for streaming on your phone, but I chose the option of a dedicated device. Hope this is helpful.

thanks for posting this option. We are waiting for our GTS (in the North Atlantic right now), and have a question. Can you take your high rez music files (I keep mine in FLAC format), and plug them directly into the USB in the console, and therefore be able to browse/control my music selections through the infotainment system on-board the Macan? I do this in my 2021 Corvette and 2021 Denali pickup and it works fantastically well. I

Guess my question is: in a car environment (not the best acoustic environment for music anyway), does an external, high quality DAP like an A/K, iBasso, Cowan, etc make a dramatic difference in sound quality of high rez files compared to plugging the FLAC media directly into the car's infotainment system?

thanks!

THX_Zora - To answer your question: "does an external, high quality DAP like an A/K, iBasso, Cowan, etc make a dramatic difference in sound quality of high rez files compared to plugging the FLAC media directly into the car's infotainment system?"
That's a great question. As you may know, due to the chip shortage, the 2022 Macans do not have the SD card slots in the center console. (The Porsche Good To Know app still incorrectly shows the SD and Sim card slots as being on the 2022 Macans.) Therefore, you will need to buy an adapter which has a USB-C on one end and a slot for your SD card on the other end. (I think SanDisk makes one.) That may work, but keep in mind that you will be going through the Porsche DAC in the PCM, which may sound as good as a portable high resolution audio player. (For that matter, the Porsche PCM may be overriding the DAC in the A/K player.) I don't know, I have not compared the sound between FLAC media directly plugged in to the car's system vs FLAC media via a high resolution audio player. When you get your GTS, you may want to start out with direct plug in route and if you don't notice a substantial difference consider getting a high res player. Keep us posted. Thank you.

will do for sure. I will have my FLAC files on a very, very small 512GB USB drive, so I will use a USB-A to USB-C dongle for direct plugin. I actually was not aware that they pulled the SD slot on 2022's. Good to know....Hey, if the only things our GTS doesn't come with are the electrically adjustable steering wheel and SD slot, I will be a happy guy given the current world situation(y)

I too have wondered if the on-board DAC is used for playback even if an external DAP is attached...

thanks Seeker.

Okay, so I found an SD card reader and compared the SD card reader vs the high resolution player and think the reader sounds just as good, if not better, than the hi res player. Regardless, the SD card reader with hi res FLAC music sounds much better than compressed Apple music. Save your money and download hi res music on the best SD card you can afford and play your music via a card reader. The first picture shows both USB ports being read. The second picture shows the SD card via the SD reader via the USB-C port #1. The third picture shows the A/K hi res player that is connected to USB-C port #2. I’ll still use the A/K, just not for the car.

If none of your endeavors work out with the USB port or someone simply wants to go back to a streaming service here are some tips to get the highest quality audio:

Set Spotify to play the highest quality music: https://support.spotify.com/us/article/audio-quality/

Apple Music, go into your App then:

“On an iPhone, you can change your Apple Music subscription’s streaming quality when you select the music tab > settings menu. On an Android phone, you can do this in the Apple Music app under settings > audio quality. From a computer, you can change this in the app by going to preferences > playback tab > audio quality.”

If you use Tidle, well that is pretty self explanatory as it tells you what is Hifi or not.
