This is a very good question and comment. I don't have enough experience comparing interconnect cables to know if 3 feet will reveal differences in sound as well as 47 feet would.
Yes, simple curiosity. My personal belief is that all cables are fixed parametric equalizers. (I credit Phil Ressler (213cobra) for this expression.)
Also, by virtually all reports, Cardas Clear Beyond is a well-balanced and musically-engaging sounding interconnect. I wish it didn't have the rhodium plating to which Marty objects, but Cardas won't make custom cables. But I should ask them just in case. (I have no idea if I hear the problem with rhodium that Marty hears, but I would prefer all copper or gold-plated copper connectors just to eliminate the question.)
We know that Cardas extrudes its own copper and fabricates its own cables, so it's a quality product in those materials and construction respects.
If anything I generally have in mind (rightly or wrongly) to "fill out" or to support the cross-over region of the system.
No, because without a direct comparison to an alternative interconnect I don't know what the current interconnects are "doing" sound-wise. They sound fine to me presently -- but that is in a vacuum.
This totally makes sense to me.
I am happy with the system currently. However, given an opportunity to add a little bit of body in the cross-over region without any off-setting negatives, I would do so.
