I'd like some recommendations for speaker cables

I understand this is a touchy subject.  My intent is NOT to have this result in that typical cable discussion. All opinions welcome.

As an update, in a previous thread I was asking for upgrade recommendations.  I ended up trading for a Hana Umami blue.  It's great and I appreciate the advice.

I've since bought a set of long (25') XLRs to run between my amp and pre-amp, which has enabled me to move my component rack behind the listening position closer to the media.  It was between the speakers.  Now, the only thing between the speakers is my amp, and it's at floor level.  This has made a huge difference in the soundstage, the accuracy and the location of things in the sound space.  Great improvement.

The XLRs I was using to run between my amp and pre-amp were entry level high end cables.  I replaced them with normal Mic cable.  Well, high end mic cable.  And the high end mic cable is way better than the audiophile high end brand cable.  I'll go as far to say the audiophile cable is awful.  I've since ordered another pair of XLRs, from a different manufacturer, to replace them.

I also replaced my speaker cables with mogami 3103 that I terminated myself.  They sound "darker" and less detailed then the cable I was using, which I'm unsure of the manufacturer of my previous cable.  I plan to re-terminate my previous cable in bananas to compare some more.  My previous cable was, maybe, too bright.  Don't get me wrong, the Momagi is good, just not what I think I prefer.

My main question is, If I'm looking for detail and a "brighter" sound, what speaker cables would you recommend I try?  

Also, do most dealers let you try cables?  It's not ridiculous to think I could work with a dealer to try to hone in on what I like, right?
