I have owned several of the highest of high-end interconnects out there,....and the in-expensive ones that are sold on the InnerSound site should not be overlooked. They are why I sold all of my big-buck ones.
Bwhite. In case you do not know, Purist Audio will build a tri wire speaker cable from any quality level in the line.
The end product is a single cable with three custom terminations, cut exactly to length for each input of your tri wire speaker.
A member of my audio group went through this same issue with his top of the line B&W speakers. Before it was even properly broken in, he forgot about any future upgrades, It resolved every issue he had.
I am very happy with Zcable's "Live" balanced interconnect between my SACD source and preamp. They have a 30 day evaluation program and exceptional concern for customer satisfaction. Their lower priced "Jazz" cable is supposed to excellent but is only available in single-ended configuration. I am also using both of their power cords, and can recommend them as well.

Sorry, I didn't notice the "speaker" part of your cable recommendation request. I am using Zero autoformers instead of speaker cable with spectacular results with OTL amps.
Walker Audio has a Mk. II version of their High Definition Links out and I highly recommend checking these out. They will probably tame any high frequency stridency you may currently have.
