Rogger,
Thanks for the advice. The SPx might be a little too expensive to go with biwire. I have decided to rewire my speakers with Lexus and go with biwire Lexus cables. These things do sound pretty damn good. They are not silver, but instead they are construted exactly the same as the hideously expensive SOGON cables. The only difference is that Lexus is copper.
Again Rogger, thanks for your valuable advice.
Mark
