Help with me make the right choice!

[Clapton101]

I have the Klipsch Reference 82 home theater setup 6.1. I have had them for about a year, they are awesome i love them. But i have the opertunity to get brand new from MartinLogan a home theater set up for right at about 70% off, the fronts i was looking at was the source's and the matinee for the center channel and the encore tf's for the rears. I have heard rave reviews about the Martin Logan line, but have never heard them, I am going to BBY this week to listen to them , What is yalls opinion, keep the Refrence (which i have a buyer that would essentially after he bought my Reference i wouldnt pay a dime for the Martin Logans and would probably profit about 500 bucks) So please let me know what you all would do, not bashing but if you didnt like one or the other for some reason please tell. All help will be appreciated.
