New platinum eclipse 7 really better than previos

Wireworld has new a new platinum eclipse 7. Had anyone compared the previos Platinum interconnects to the newer 7 version? I have the older version and like to hear from anyone who has compared them. I will likey buy the new cables but it help to know if there's an improvment before I leap.
Why would you purchase newer cables without expecting an improvement? New and/or different models is the only way to stay in business so it isn't necessarily expected that every new model result in a sonically better product.
Well, yes your correct, I don't alway expect a real improvement, hence my reason for asking the question..
