Quick answer: you can't compare an old Buddy Rich album to Rush in terms of how to set your tone knobs/EQs, so there's no catch-all settings to use. Buddy's stuff was probably recorded, for the most part, with one or two condenser mics picking up the whole room, which is why his generation of drummers were always so cymbal-heavy; it's the only way they could get heard in the mix, cause the other instruments and the lack of mic proximity would wash out their low end (actually, drummer bandleaders like him and Krupa probably got treated a bit better by the engineers, but you get the idea).

Rush, on the other hand, have always recorded with state of the art gear, and on a good system you can hear every nuance of his snare hits, every squeak of his kick pedal (ok, it never squeaked, but you know what I mean).

As such, there's only one measure of good sound for your car: your own ears, which sound to me like they're quite up to the task.

That said, bear in mind that you're talking about a car here - hardly an optimal listening environment in terms of acoustics, and believe me, you're listening to a very good system as car audio goes, especially for a factory deck - I've never had a system that sounded this good. The closest I've come in the past was a Clarion deck I had in my Corolla, and after subsequently trying Alpine, Pioneer and Kenwood (thieves like aftermarket decks), I would always go with Clarion in the future if I was going aftermarket. Fortunately, Toyota has seen fit to take care of us with this system.

But, like I said, it's a car - if you're an audiophile, you'll never, ever be totally happy with the sound you get in your car. Just accept that very good is the best you'll get, and be happy for the rest of your days.

PS. Ever notice how Bose systems are always displayed in their own little area, out of earshot of the rest of the audio gear? That's because Bose's audio quality is crap, and they don't want anyone to realize it. :>
