I have been using SS The Music Reference speaker cables for about 4 years. I also use SS Silver Signature interconnects and power cords. The Music Reference cables are very neutral - not adding or subtracting anything, but are also revealing of what is upstream from them. Very true to the source, in my case, my turntable. I have been happy with them. Have tried other cables for the short term, but return to the Silent Source. Never heard them with horns, so I can't be of much help there. See if you can borrow them for an audition. Caveat: Silent Source cables need a little time to "settle in" after having been moved or installed. Don't be too quick to judge what you are hearing until they have a few hours in your system.
