Why do I need cables ?

The basic function of audio cables is to carry an audio signal between two pieces of electronic equipment. Without cables you cannot connect your equipment, so the items you own would be essentially unusable. The sorts of equipment that you may want to link together include instruments, cd/dvd/mp3-players, turntables, tuners, microphones, pre-amps, amps, speakers..

For all this equipment we will need signal cables, speaker cables, mains cables.

There are many discussions on internet about cables and there are many maniacs that pretend they could hear the difference between different cables. Maybe they could but these are exceptions, for all of us a cable that cost 20$ will sound exactly the same as a cable that cost 200$. I'm not saying that quality of cables is not important, in fact is very important but you will never need a 200$ cable that connects your cd-player (even an expensive one) with your preamp.

With the speaker cables is another discussion, these cables can really affect what you hear.

A good speaker cable will have a low resistance, inductance and capacitance. Speaker cables must be selected according with their length and the power of amplifier and speakers.

For powers between 10-100w you will need 12 Gauge (3.3mm²) Wire.

For powers over 200w you will need 10 Gauge (5.2mm²) Wire
