IMHO,
Your Harmonix interconnects and speaker cables are going to be damn hard to beat.
My guess is if your not happy with the sound it's not your cables, most likely your room needs some work, or perhaps a weakness in a piece of equipment however I have no idea where the weakness would be, it looks very good to me.
Of the cabling you mention, the only one that *might* better the Harmonix would be the CT!
Do you use dedicated circuits and high quality AC outlets?
