What I was trying to say was that after waiting for three different contractors to come by and estimate the cost for running the wires and mounting the banana plug jack panels, I haven't called anyone and 'settled' for the jacketed wire laid against the molding. It is hard to see - and my wife doesn't even complain. Rolling the spool helps straighten the jacketed wire wire, too. If your threshold is easily removed, perhaps you can find one with channels routed - or milled if it is metal - for your cables. I was fortunate - mine had to pass over an unused gas fireplace white marble - and, again, it blends in. Should I ever want to use the fireplace, I can always pull some of the copious excess and lay it out on the carpet away from the heat. Right now, it is partially obscured behind the decorative fireplace screen, too. I am glad that I got the white jacketed over the usual clear looking zipcord as, from experience, that wire is quite visible.
