I have had both a 2021 M5 with the Bowers & Wilkins and now a 2022 M5 CS which only comes with the HK. The B&W is definitely better than the HK all around, especially at higher volume. But I would say the HK is about 80% as good as the B&W to moderate volume for me (which for others may be high volume) and more like 65-70% at very high volume. However, and this is important, the B&W in the M5 is nowhere near as good as the B&W in our X7. The sound in the X7 and especially the lows and mids blow the B&W in the M5 out of the water, not even close. Hope this may help those of you on the fence.
