5 of these cables are less than 3 weeks old. I used them before deciding to go with XLR cables to connect my preamp to amp because I'd never used XLR interconnects before. Three of the 5 nearly new cables are the Silver series. MSRP: $27.55 each. The Silver Series are Digital Audio Cables - 8mm Silver, Triple Shielded Conductor w/ Locking RCA Males 3feet long. 2 of the nearly new cables are the Blue Series. MSRP: $25.55 each. 2 cables are brand new and are the Blue Series. The Blue Series are 8mm Triple Shielded Single RCA Male to Male Locking Plugs 3 feet Long. The cables fit snugly and you can tighten the ends so that they "lock" into place for a sure and firm connection. The nearly new cables will be carefully packaged individually in re-purposed boxes in the trays you see in the pictures. CALRAD is a family owned business located in Los Angeles. They are a major supplier of cables to the recording and movie studios here. The price is for all 7 cables together.
