Well even my Jetta FSI Turbo can tell the difference as I am absolutely sure a Ferrari or say V8 Supercar can, I guess the point is that if your running around in a KIA you more than likely wont tell the difference.
I guess if your using a crud head unit then no matter which amp you use it will only make the crud louder not better.
Is it not the duty of the industry to guide people, give them understanding and raise the general standards ?
