A digital coaxial lead is similar to a standard phono to phono but it uses special 75ohm cable which enables full range digital signals to use just a single connector. You may have noticed an option for digital connection on the back of your amplifier, DVD or CD player. Connecting any of the latter equipment together with a coaxial lead will give far better sound quality than standard analogue connectors and is essential if you have a Dolby digital or DTS equipped amplifier.
