Jon,Maybe you should try the Shatki On-Lines. These will allow you to dial in the ringing mode of the speaker cable, interconnects, digital cables, and power cords. This way you can tailor each cable sonic signature much closer to the speakers sonic needs.
Another great product is the HighWire Power Wrap (this product was used in the design of HighWire's speaker and interconnect cables) idea which is nothing more than magnetic wire (teflon insulator) grouped together to make a 12ga spiral you fit around the cable. Center spiral to center of cable. By moving the spiral towards the speaker an 1/8" at a time you could adjust and null certain ringing modes within the cable to alter the overall sound. The Shatki is used the same way.
Your could even try large ferrites at the speaker binding posts. Many different ideas...
Have you ever tried to ground the rca connector in a component to the chassis. The amount of noise removed from the signal is quite staggering. As of now I and many others have tried this trick on solid state and tube equipment with no side effects. Works best when coaxial cables are used. Do not try on digital output.

This doesn't always work. Sometimes it lowers the noise floor, but sometimes it screws up the imaging, soundstaging, and plain reduces resolution.
In my experience, it depends on how the internal grounding is done. If the internal grounding is based on bus-grounding concepts or has lots of common impedances, bleeding off excess HF & RF energy to the chassis ground as quickly as possible is beneficial (personally, I would try tying the RCA ground to the chassis via a small film cap first, rather than going for a direct chassis connection from the very beginning).
But if the internal grounding is based on a one-point ground, chances are that tying the RCA ground to the chassis will worsen the sound, not better it. Technically, this makes sense, because tying the RCA ground to the chassis introduces multiple ground paths and common impedances, and is at odds with one-point grounding.
I use one-point grounding in my own products (and they are wide bandwidth designs), and tying the RCA grounds to the chassis is a decided step backwards. OTOH, I have modified bus-grounded components to this configuration and had the sound improve. YMMV.
