Audio Cables

To send sound from a source to a pre-amp, processor or DAC. Or to send signals from pre-amp/processor to poweramps or subwoofers.

Phono leads- you can use the included leads you get with the units until you decide on specific make/models. It is worthwhile buying decent quality phono leads- improvement in bass response, treble detail & less background noise due to better shielding. Buy the most expensive one for the source to amp connection, and cheaper ones for Pre-Power connections

Digital coaxial (75ohm) leads look identical but have 75Ohm resistance, and you only need one for a stereo/multi channel signal. Don't go stupid with the amount you spend on digital cables. £50 maximum each. Also used for composite video.

Toslink (Optical) cable. I would use optical cable for VERY long lengths, if required (for multi-room) Say 20M or longer. I prefer coaxial cable as it's more durable.

Aerial (75Ohm Co-axial). Use well-shielded coaxial if possible, as usually you would have quite long runs from the TV/FM aerial to the wall socket, including other routing throughout the house for multi-room audio/visual setups. Used for TV aerials. Can also carry FM from omni-directional FM radio aerial.

XLR (balanced). Used for professional equipment. Lower noise floor than standard RCA, and higher dynamic range. It has a separate ground (compared to RCA's shared ground with the - wire) XLR's can also lock into place. Ideal for long lengths, ie, rock venues. Used for analogue & digital connections between high-end CD transports, DVD transports, processors & poweramps.
