Discovery Cable female DIN to male RCA with grounding wires. Usually used for connecting a turntable to a preamp, integrated amp, or step up transformer. Clearaudio connectors on each end. Four feet 2 inches long. They work well and sound very good.Very light use 3 years ago, has been in storage. Rated 8/10 because there are some scuff marks on the RCAs where electrical tape was removed. They had been wrapped with tape because inputs where they went into on the integrated amp were close together.
