If possible if you are near a studio, I recommend you ask for a demo of the sound system. The guy at the Natick studio put together a playlist which shows off the capabilities of the car, maybe you can ask your local studio to reach out to him and see if he can share the playlist. To fully utilize Atmos you’ll need to subscribe to Tidal HiFi Plus which is $24/month (free 3 month trial with the car I think?), although Apple Music has Atmos and is cheaper and should work when we get CarPlay. A couple songs on Tidal that will show off the capabilities of SSP in Atmos are INXS Mediate, Prince’s When Doves Cry, Billie Eilish Oxytocin and The Doors Riders on the storm. If you’re not a music nut and don’t care about super high fidelity save the $, which is a lot of $ when you factor in the Tidal subscription, the regular sound system without the full 21 speakers and Atmos enabled should still sound decent, the other additional difference that there’s a second amplifier/DSP for SSP (thanks
@DreamTour for the awesome tear down of the system!)
