Really expensive systems that sounded great?

I’ll take this $100K system all day, every day:

Mercedes-Benz’s implementation of Atmos looks to go even further, with a whopping 31 speakers scattered around the car (a list that includes six 3D speakers above passengers, four “near-ear” speakers for the two front seats, and an 18.5-liter subwoofer). Each seat also features two hidden exciters apiece (for a total of eight in the car), and everything is powered by two amplifiers with a total of 1,750 watts of power.

To start, Mercedes is offering Atmos in its top-of-the-line Maybach model, followed later by its S-Class cars featuring its new MBUX infotainment system. Unfortunately, given the price of both the Mercedes Maybach and S-Class cars, having the hardware to get the full Atmos experience won’t be cheap.

The entry-level S-Class vehicle, a 2021 S 500 4Matic sedan, starts at $110,850, and the Burmester 4D surround sound add-on that’s necessary for Atmos is an additional $6,730. Customers of the top-of-the-line Maybach model won’t have to worry, though — the upgraded sound system is already included in the base $185,950 price tag.

Now THAT is a system, talk about a Vehicle baby:

BTW, if you are spending more then even $10K on a "music reproduction" system and it isn’t able to do atmos you are taking a blow torch to your wallet because you will need to sell that gear in 5 years for 20 cents on the dollar and upgrade (again, ugh):

I have heard the Ultra 7’s in Atlanta a few times.  The first time was with ARC Ref 6SE and 160M amps.  They made me sit up and take notice. They sounded great. That was summer of 21. Then last November I heard them again but with Dan Agostino gear. Not quite as impressive as I remembered it before.  Both times the sources were the same- the DAC and vinyl.  Just something to note.  

I have an S-Class.  The sound system is great.  I play it at a very low volume.  It doesn’t hold a candle to my home stereo.

+1, what type of entertainment system does it have?
