Those who are few interested in the hi-end world will certainly not be able to believe that there are connecting cords from ampli to speaker  have a price to tens of thousand USD, and the pieces of rubber machinery basing with small size as a beer bottle cork but they are equivalent of more times.

Slap-up conductor is very expensive.

When only trial listening and reconcile with normal others, you will realize the logic of surprised numbers and understand that every small detail has a "contribution" to sound quality system. At first, we will mention to Digital Cable which brings the signal from CD device to D/A (digital/analog Converter). Often, these devices in the job provide 4 abilities to use Digital cable: Coaxial standard - RCA (with connector form as lotus), standard XLR (also known as Balance – Canon likes microphone connector), optical cable which leads digital signal according to the form as optical and standard Toslink also uses optical cable, but according to the manufacturing formula of AT & T (U.S.A). Quality of transmit the signals of 4 above types depends on the length, manufacturing materials, and know-how secret of each carrier. However, when using "blind analysis" (the audio specialist will heard in the dark), it is recognized that type of Balance (XLR connector) brings sounds more exact.

The second type is connected from D/A device to pre-ampli and from pre-ampli to main-Power, electric cables used to be called an interconnect cable. Standard connector for this type is also RCA (lotus) and XLR (Canon). If your speaker is designed as Balance circuit, it is best to use XLR because the sounds will be clear, warm and "full" more. Normally, materials for manufacturing cable are a copper alloy or special silver. Some of the most famous as Purist Audio is researching and designing cables being soaked in oil but still ensure maximum transmission of audio signals.

The third type which transfer signal from ampli to speaker called speaker cable. Popular length is about 3 m, and it is rare longer because the sound quality is inverse proportion with length of cable. Being as interconnect cable, speaker wire is made from copper, silver and a number of special alloys. Thanks to the secret of each manufacturer that quality of speaker wire (attached to the purchase price) are very different. In addition, depending on type of music usually heard and trademark of your computer, you can refer to expert to find out the appropriate type of wire. There are a number of players who have prepared a variety of wire for easy change to hear these kinds of different music.

Many speakers have 2 separate inputs for 2 high-frequency (treble) and low (bass), so you can use bi-wire to exploit that advantage. The highlight of this wire is stereo effects increased remarkably; sound at the high points is more brilliance and sharper.
In addition to the above kinds of wire signal, you should also pay attention to the power cable. The leading companies such as Siltech, Transparent, MIT, and Wireworld are providing the power source cables which are able to filter mixed sound and high-impulse, and ensure the pure of sound.

Of course parts in a hi-end system must have a general level. An expensive wire is connected to a normal ampli will not be effective. Therefore, the experts made the following formula to help the players refer to when allocating the budget for speaker system: 50% for the electronic (CD, D/A, ampli ...); 40% for speakers and 10% for the wire. Assuming that the total value of your computer staging is USD 10,000, you will invest in the wire about 1,000 USD is right.
Some famous hi-end wires: there are many manufacturers specializing in producing all kinds of high-level wires for this special market. Every year, the professional audio magazines introduce all kinds of these wires and analyze strengths, weaknesses of each. Some trademarks received a high evaluation are Van Den Hul, Tara Labs, Straight Wire, Purist Audio Design, MIT, Kimber Cable ... However, as noted under each line of pharmaceutical product advertising "read carefully the instructions before use", when selecting the type of wire, you must try to "try before making decision".
