While you are in Denver you would enjoy a visit to our shop. You mentioned cable upgrades, we carry Kubala-Sosna. Wilson has used Kubala-Sosna to demo their speakers at a couple of the CES Shows. Not sure I can send an attachment with this email but if you respond I will send you some information.
Our main speaker line is the Wilson Benesch. We have taken the Curves to our Rocky Mountain Audio Fest and received very fine show reports. Below is just one of them from TAS. I also have the Wilson Benesch Torus Infrasonic Generator. I am not a fan of sub woofers but the Torus is a totally different animal and can be integrated with the fastest speakers even electrostatics.
The best

“Though I've heard the Wilson-Benesch Curve floorstanders many times before, I found that they sounded spectacularly good as driven by Kara Chaffee's amazing deHavilland tube electronics . Nothing I heard at RMAF, save perhaps for the far more expensive Vandersteen/ARC system, could touch this rig for sheer midrange purity, detail, three-dimensionality ." Chris Martens TAS
