I have owned the Quattro fil and own the Coincident. In my system the Coincident has a wider, deeper soundstage without bleaching the tonality. The Quattro fil never sounded like music. I have been using the OTA IC from 47 Labs and this skinny, whimpy little cable has out performed these two cables in the audiophiles check list of what a cable should do. I have been listening to a $3500 IC from Venture. The Venture cable is worth the $$$ when compared to the Quattro fil I suppose. The 1 1/2 meter of OTA IC is about $75. This $75 IC not only competes with the Venture IC but out performs it in many areas thar matter most to me. Go in with a buddy and give this stuff a try. You do not have to spend the big bucks to get a great performing, musical IC. I'm sold.
