I have the SA Mantra 10s. They are your speakers as monitors (one step down). Before I had the SA 505 there entry stand mount. I have always used solid core exposure wire due to having an used exposure amp. I have had great results with these solid core wires. While researching newer cables someone on another fourm told Me his SA 505s were great behind solid core wires. This leads me to believe soild core are a good match for System Audio Speakers.
I would try the cheap wire first. If good go to a nicer pair used before you go crazy. I thought I saw 8 ft pair of exposure wire for 100 bucks. PM and I can direct you to ad. (No affiliation with seller).
