Has anyone hired cyrix7x86 on Ebay to "upgrade" their crossovers?

Thank you for sharing your knowledge. Now I have to find out if our friend on Ebay has considered the DC issue AND actually "ear" tested his crossover upgrade for the SL700

What was the result of the conversation with cyrix7x86 and did you get your crossovers done?
I hope he's legit as there is a real gap in availability for some of the services he's offering.

Whether he tests individual components before using them and whether he deviates from the original design are important details.  I can (and will) ask him directly, but hoping to hear from someone who has experienced the results.

speakers must be custom tuned to YOUR ears. 

I never did use his services. I decided I did not want to take a chance and mess with the already wonderful sound of my Celestions.
