I would tend to agree with Foster_9 and his fellow Agoner. When I think back to all of the cords I've been through, the ones that have the most extended, detailed high's tend to lack 'musical weight' in the bass. I say musical weight, because I have heard some of these cords go plenty deep, but their bass tends to be very tight (not necessaily a bad thing), so they don't sound as full, or have the 'apparent' bass punch of some other cords. The cords that I've heard that have full, robust bass, tend not to have the speed or resolution to make the high's airy and extended.
I think the best thing to try to do is to balance the cords through the system, not use all of one type. Play around a little using 'full-bodied' cords in combination with 'resolving' cords to balance the sound to your tastes.
FWIW, I've also noticed that a cord's soundstage is give and take too. Cords that have a deeper, 3-D stage tend to lack the width and height of more forward cords. Cords that are too forward offer a large 2-D soundstage. I prefer a 3-D stage, I don't care for the 'front row' perspective, but I have heard too deep, where the band seems to be playing out in my driveway. Again, IMHO the key is balance. Experimenting with various cords until the stage size, like bass weight and high's, are balanced to the taste of the system owner.
Looking for one magical cord that can do all things on all gear is chasing the impossible dream, IMHO.
