Use whatever cables are appropriate for your current gear. So, if your equipment is unbalanced, then use unbalanced cables. If you are connecting unbalanced gear to balanced gear then make sure you are using the correct cable for that. It really depends on your gear. Using balanced cable on unbalanced gear will not balance it, or make the sound better.
Also, there's no rule that says balanced gear sounds better than unbalanced. It's basically about long cable runs and rejecting RF interference. So if you are using runs only 2 meters long you should be fine with unbalanced unless you live next to some major source of RF interference.
Hi
Actually there is an area where balanced equipment scores over unbalanced and that's on the matter of ground (earth) loops. In unbalanced equipment the ground/chassis of the device is the return path for the signal. So, if you have a piece of sending equipment, the signal will travel along the signal core to the receiving device and then return, via the shield of the cable, back to the sending amplifier.
If the sending amplifier is at one ground potential and the receiving amp at another, the difference in the two potentials will be superimposed on top of the signal.
In point of fact, in a small room setting, this is unlikely to happen because all the equipment is probably plugged into the same power strip. I just tossed this in to show a further handicap that unbalanced wiring has over balanced. The interference rejected by the balanced configuration doesn't have to be RF... it could be a stronger audio signal. RF can creep into amplifiers in the most insidious fashion... often it can picked picked up by the output of an amplifier and works its way back through the amp via the negative feedback path.
Still, it's a valid point... if the equipment is unbalanced there's little point in using balanced cable except for a little dodge that I do.....
If you use a twin conductor and shield cable, you can use one core for the signal and then connect the other core (at one end only) to the shield. You connect mono jacks (or whatever) at either end of the cable using the signal core and the shield.
The effect of this is that the two inner conductors are in effect a twisted pair. A twisted pair has high interference rejection and then you have a shield around the outside of the twisted pair.
That's one well shielded cable!
