Ehider, this is an interesting perspective. You're probably referring to the CS.1. From what I've read, a number of people seem to think the CS.2 can't be beat by anything below $40K. If that is true, and suppose most audiophiles cannot afford anything below $40K, then the CS.2 is effectively doing something that no other speakers (these people can afford) is able to do...in this sense, the comparison with the Quad might make sense. There is no other speaker like that for most people given their budget.
One way or another, what I find interesting in your answer is that you seem to suggest EP is some sort of revolution in performance/price ratio -- like, you can buy and enjoy the equivalent of a Porsche at the price of a Corolla -- and that is remarkable.
