There isn't a huge difference between class units. And nowadays, there's a lot of blatant nonsense surrounding high-end home audio, like little stickers you can put on your speakers or "treatments" for CDs to give them a better class of bits and bytes - homoeopathy for the audiophile.
However, nobody is going to pretend that a pocket tranny is going to sound as good as a Linn system, for example. The big question is, is the difference between the 310, the 510 and the 510 with Dynaudio in the "pocket tranny vs. Linn" bracket, or in the pink stickers for your speakers bracket. I suspect its somewhere in between actually - that there is a difference, but it may not be as enormous as we like to think.
Listening tests are very subjective, particularly if you can't switch instantly from one version to the other, and they're enormously affected by volume - we're all inclined to rate the louder sound as better irrespective of anything else.
I'm not disappointed by the 310, but I'd like a listen to the Dynaudio some day.

Between the electronics, no, or at least incredibly unlikely, at least not to the human ear.
Between the different speakers, Dynaudio and standard, yes, in all probability there is. How much, well that would depend on various things and only a (double) blind test would be much use determining that given the problems associated with audio testing and comparisons. Then there's preference to add to that; not everyone likes the same speakers for good reason. And then to top it all, you have the considerable amount of ambient noise in a car to add to the mix.
My (educated) guess is that when a Golf is tootling along, even if you could tell the difference between the standard speakers and the Dynaudio, there wouldn't be the awesome difference that the exorbitant price disparity would imply. Certainly not enough for me to shell out that kind of money and this is coming from someone that spent 6K on the front 3 speakers in my living room at home.
