don't know if this info is out there, or if any current owner is willing to snoop and do a little teardown behind their door panels, etc.. but, what are the oem parts for the studio sound system? i am a music and audio fan and a bit dismayed at the reports that even the $1k more expensive 'studio sound' system is less than impressive. lack of bass, funky high-end noises and all sorts of talk about dolby multi-channel (seriously???) makes me more than a little nervous about the system. couple this to my test drive experience, which, while it wasn't bad per se, audio wise, i did not come away impressed. my memory is that the sound was very diffuse, lacking decent staging (amp and speaker selection and placement) and somewhat lacking in power.. (not volume, but amp push, distorting at top levels) i played classical from the on board library they had loaded i believe, but listen to all kinds of music. also, not happy there isn't native support for apple lossless.. bit of an oversight imo, unless it's a licensing thing.. and, why can't we play from small platter drives like the perfectly sized western digital my passport...?? only needs standard usb bus power, (5V i believe... can't remember). the thought of going to al and eds and installing new amp and speakers in this expensive car is plaguing me.. but, i want beautiful sound in this thing. way back in 1995 i put an alpine amp and mb quart speakers, (split tweeters my custom placements), and sub in my then ford explorer for about $1100 ... haven't had better sound since. not in bmw 5 series, not in lexus with levinson... kind of a drag. why oh why can't it be a great sound system.. ?? current owner thoughts, rebuttals, confirmations, all... welcome.. please. and thanks.
