Best speaker cable for Genesis speakers


I am looking to upgrade my speaker cable, and am hoping to get some feedback as to what would be some good candidates to audition. My speakers are the Genesis 4 tower units. Currently I use the Shunyata Orion to run from my Levinson 33H's to the Mid/tweeter towers. This is the cable I am looking to upgrade. I'm not sure that bass response of a particular cable is important, because as I said, this cable is just going from the Levinsons to the mid/tweeter towers, obviously handling the midrange and tweeter ranges only. So, do I only care about the mid to upper performance of a speaker cable, and if so, what is a top candidate to consider? As for the Shunyata Orion....I have no complaints, the system sounds awesome......but I also don't know if there is an opportunity to considerably improve the sound with a cable upgrade, or if it would be a sideways move!!

I ended up buying the Stealth Dream, and do like them very much! There are so many good ones out there though, where to stop the madness!!? I would love to try the Tara, and Odin, and Elrod Gold........but cripes, the cost. The fact that the Stealth has a great reputation, but did not blow my Orions out of the water, has me content that perhaps the stratospheric cost of the upper crust of speaker cable is not something I can live with given the bang for buck considerations. Some day perhaps I will try the Gabriel Golds' new speaker cable that's out.......their ic's impress me so, even compared to the Stealth, that perhaps there is some good value in speaker cable to be found there as well!!
I've been happy with Ultimate Cables Silver Series on G350's. Relatively inexpensive mix of milspec copper/silver/teflon from a boutique/garage project of Quebec engineer. Because the ribbons are purely resistive and don't rise in impedance/frequency like traditional dynamic speakers, some cables overcompensate being artificially bright on Genesis. First impression of Carl's was "smooth" but not missing anything. Would be nice if he published specs but, for the price, it's no risk.

Too late... sorry, rarely look at this category.
