These are both great cables. I like Sean's analysis of the situation. Aren't the AU24 substantially more expensive than the Goertz copper line?
As for Dan's question, my own experience many years ago was that it was worthwhile to build an expensive high quality car audio system because of the intimacy of the environment. This seemed to over-ride the issues of road noise and impossibility of imaging. For me, I end up using my time in the car to catch up on radio news or phone calls, so it would not be worthwhile for me, but might for others.
