Wireworld

Im a Wireworld dealer as well but have not had the silver eclipse speaker cable yet. If it follows the improvements via the interconnects, you can expect a cleaner sound with improved high frequency extension. The soundstage would also blossom a bit more. 

Dont hesitate to to call Wireworld direct as they have quite detailed information about expected improvements as you move up the line. 

why dont you ask https://www.underwoodhifi.com since he is a dealer.  I am sure he could give you some input on the cables .    

I'll give you a bump because that is exactly what I want to know!
