Even the most expensive and top of the line headphones such as the Sennheiser HD800 coupled with a powerful DAC and amp will never be able to compare to what it feels like to have a few subs, high ends speakers and tweeters, properly installed with its own amp in your car.
I've heard a few nice car audio systems myself and I must say, the sound and detail (especially the loudness factor) will never be able to compare or even be on the same caliber as a small pair of speakers which encompass a headphone, even an audiophile one like the HD800.
The loudness, it's surreal and amazing.
Example, Steve Meade is really a true audiophile. 30,000 WATTS or more. Easily over $100,000 in this car, I mean each AMP costs $20,000 I think.
