I've put over 16k miles on the GT4 and never, ever turn on the stereo. The PCM screen remains off at all times too. Same as Jx951 and blade7, I prefer to listen to the sounds of the car.
Even though I configured the alleged top end Burmesters in the two latest P-cars, I did so because B-Mesters are usually expected and it's best that they are there for others down the road, including future owners. It is pretty much a demand option in that respect. There will also be times where I want to have something somewhat listenable in the car, so it's best to be prepared.
However, for me, music in a car never approaches that of a halfway decent in-house system. I realize that it's a very personal choice for each of us, but I feel there is just too much going on in a car noise-wise, especially a sports-type vehicle with its performance tires, sport exhaust, harsher ride, etc. Add in other road noise from traffic, loud trucks, etc., and music will be rendered relatively poorly no matter how good the system. Also, I generally don't like additional distractions when driving. (That definitely includes phones. No Bluetooth BS interruptions for me!)
Having said all of that, if I were to have a Chris White 944 or any new vehicle, it will have the best stereo available for the reasons mentioned. Who knows, maybe I want to sit in the car listening to music while it's in the garage or otherwise not running.
