It is known that the engineers did not have a Model S when they first created the setup, and they did with the X which provided a better outcome for the same price. The fact that the audio debate still exists should alert Tesla that its not up to par, specially at the $2500 price tag. Considering that it has been around for a while any reason why the audio engineers haven't gotten ahold of a Model S and improved on their package? I like listening to music when driving and I would opt for the upgrade but when I listened to it I don't see the quality. On my Range Rover I get goose bumps on certain notes by singers like Adele, actual goose bumps first time it happened it was so weird. Anyhow just venting really because I don't want to get the standard audio and open the car up to add a sub like if I was still in college and much rather spend more at purchase but see the value.
