I purchased this to connect a digital to analogue converter box between my Toshiba LCD tv, which only had optical output for audio. The sound from the television itself was thin, tinny and flat, with little detail when it came to watching DVD's and using a PS3. The idea was to buy the DAC box and connect to my hi-fi (Rotel & Q Acoustics) using left and right phono cables. I'd been into places like Comet and Currys only to find they wanted an absolute fortune for cables like this, so I decided to buy the one recommended on Amazon when I purchased the DAC. Well, I have to say the sound quality is awesome! The quality of the cable itself is definitely not cheap and with it's noiseless performance I would recommend it to anyone in the market for a decent digital optical cable.
