Riddle me this, riddle me that....ok now can someone try to explain that?

[bacchanal]

A product that has to be sold to everybody for the same price is called a "commodity". No producer or vendor wants their product to be a commodity: they want to sell it for more to the people who are willing to pay more.

Of course, if the product is obviously identical the maker can't ask the rich buyer for more -- they aren't that stupid. So he enhances the product in various, often trivial ways that cost him much less than the increase in mark-up he hopes for. This way his rich buyer can feel he's getting more and will pay more -- never mind that the actual improvement is slight or nil.

You're forgetting form over function. Even if the Signiture series is only a trivial increase in sound quality (I don't know since I haven't listened to them), they still have significant aesthetic improvements. People with money often are willing to pay real money for aesthetics. It may seem trivial to you (for the price), but if you're loaded and your spoilt wife just can't stand the thought of veneer...which speaker are you going to go for
