Many fine recommendations listed so far.
I have a Cullen Crossover, Triode Wire Labs 8+ and a 10+ along with a Signal Cable magic PC and 3 Signal Cable Digital References.
I wasn't a fan of the Signal magic however for my system and set up the Digital Reference is the most neutral PC of my group. The Triodes are very close but a little warmer presentation that I do not need emphasized. The Cullen I found to be slightly heavy in the bass region but hasn't been auditioned in my main rig for a long time.
The Digital reference can be used anywhere. It is 12 gauge which is sufficient for everything with the possible exception of the most powerful amps.
Pricing for this cable which recently was an absolute steal is still a great bargain. The one stinker about it is that it's difficult to work with being so darn stiff.
These cables have been evaluated with my Tekton Double Impacts which if memory serves is the speaker you're trying to match up.
Also a big "Thank You" to Charles for alerting me to the standby feature of the RS2T by utilizing the remote. Once I got the unit to power up, the standby has worked at least a dozen straight times. I can only assume it will continue as such until my replacement finally shows up.
