First of all, every IXOS product is extremely well made and well spec'd on their website. I decided to give this award winning cable a shot and temporarily replace my high end Monster Optical cable. IXOS plainly states on their website that their research has determined that Coax cables are better for HT than Optical. All I can say is that they are right on point! This cable delivers fuller, more robust, and more engaging sound than my Monster Optical cable. This is the first time my KEF Q7 HT has sounded like an actual MOVIE THEATRE. Tremendous product - check out their banana plugs!!
