Personally, I feel most of those speakers look like the manufacturer was much more concerned with the way they looked than the way they sounded. I understand when you're a millionaire it's important to have something nobody else has, blah, blah, blah... but I'd be very surprised if very many of those sound remarkably better than our Axioms.
Rich people don't actually listen to music anyhow, they're too busy making money... aren't they?
