There's no difference in how the aperture blades behave when using the ring or not - either way, the lens stays wide open until you press the shutter. But on some lenses, using the aperture ring hastens the eventual breakdown of the ring itself, so that would be abnother reaosn to avoid the ring. But mostly it's as said above - using the aperture ring is fine if you don't mind losing all automation, but since you *also* lose your meter, it's limiting yourself unnecessarily. You can shoot in manual mode in A position if it please you to shoot manually, but at least you still get a meter when the lens is on "A".

To borrow your analogy to the stereos, moving the needle on the turntable yourseff is fine if it pleases you, but not a great idea if it also limits the functionality of the system in other ways (say, disabling the volume control or EQ). And that's basically the case with using the aperture ring.
