I got Bose on my Macan4. I don’t know about Burmester on MacanEV, but I have Burmester on GLC300. The difference is huge: Burmester on my GLC sounds so rich in all frequencies, while Bose on Macan4 is very rudimentary. It’s nowhere close to what Burmester can sound.
Short summary for those who do not want to watch it: he thinks the Burmester is too expensive for the quality increase over Bose. However he recommends Bose over stock.
I have the base sound system on my 4 and am very happy with it (also the extra room in the trunk). The bass is more punchy than I expected. I haven’t heard the other ones so can’t judge how much better they are.
I think a lot of this comes down to expectations and whether one is truly into HiFi. Most people that are overly critical of these systems are coming at it from a completely different standard of required fidelity from their audio system. If you've spent any time in this world, you'll soon realize that no system is perfect, there is a trade off for everything, and it's the eternal search for the holy grail. I'm not saying that to dismiss those opinions.... those that have experienced greatness in audio systems truly can tell a difference. It's just that to the everyday listener, we are happy with the first 75% of audio quality, while the audiohead is obsessed about the incremental 25% of diminishing returns above that (and willing to pay for is....)
I have the the Bose system. I'm not generally a Bose fan. The Bose system in the Macan sounds good to me. Starts to distort a bit at higher levels, but with certain types of music it sounds great to my ears. That's all that really matters and so I won't let anyone tell me otherwise. I personally think it sounds better than the Burmester in my Mercedes GLS (but that might be partly because that vehicle is a huge boat). Not as good as the B&O that was in my previous Volvo XC90. Given some of the very very bad experiences with the Bose system, I do feel like must be some issues with installation/tuning of the sound system in certain vehicles.
Also worth noting is that the diaphragm in the speakers must be broken in. When you first get your car it won't have the full range and response that the system will ultimately be capable of.
If you just got your car, don't judge the sound system (regardless of make) by what you hear now. Give the system a couple of weeks and if you want, help the break-in process along by playing music at a higher volume than you usually would.
ÂŁ3k isn't expensive in the world of Hi-Fi, where high end systems can cost more than an entire Macan Turbo, so I wouldn't expect that much even from the Burmester system. I have the Bose in my car. It's fine for a car, not Hi-Fi, but no car system can really compete with a decent home set up.
I am very satisfied with the burmester. I had the bose in my taycan and it's not comparable. After given the price difference I understand that some people think it's not worth it. The important thing is his personal feelings.
