This is the minimum quality interconnect that we'd recommend for a CD player or source of CD quality. The Cambridge AUD300 1M follows on from the Cambridge Arctic and offers a number of advantages over the AUD100 that really "open up" the sound. The Cambridge AUD300 is shielded not just once, but twice - with both a braided screen and aluminium Mylar one. Most noticeably, the AUB300 is the first of the acclaimed Cambridge interconnects to use metal bodied RCA phono sockets. Featuring 24K gold plated connectors and clasp ends, you will not get a better connection for the money!
