I'm not quite sure which model of SonoCable's these are. They were my father's, and I'm selling off his estate. After some research, in my opinion, they match up closest to the SonoSeraph's, but if anyone has more information, I would be grateful. Looking to get $140, but willing to negotiate.
The SonoSeraph is the little brother to the Seraph Select, and is built with three stranded silver-plated copper conductors. One conductor is used for the positive signal, and two are used for the return.
Our silver-plated copper is cryogenically treated, and extrememly high specification and insulated with teflon for maximum preservation of the signal. The silver plating on the copper also prevents a chemical reaction from occuring between the teflon and the copper which can affect durability of the cable over time. All parts of our cables are cryo treated prior to assembly.
This cable is terminated with heavy-duty, gold-plated, copper alloy split-tip RCA plugs and soldered with Cardas Quad Eutectic Solder.
