Balanced Interconnects??

Balanced cables have additional circuitry to cancel out noise. They originated in professional recording applications where there was a great potential for noise interference. I would suspect that your equipment has rca connections only. Rca's have the little round connectors that are a little bigger than a pencil head. Balanced connectors are a little smaller than a dime, and have a locking tab. Balanced circuitry is supposed to sound better due to this quietness. I have never directly a/b'd them, but one of my friends who has an extremely high end system (75K worth in a treated room) commented that he could not tell the difference. If you have balanced input/outputs, buy balanced cables, otherwise buy RCA's.

Balanced connections on XLR jacks can send both sides, positive and negative, of the waveform. RCA connections can send only one side, usually the positive. So balanced stereo stuff has four signals to work with instead of two, and why it costs more when it's for real. This creates the possibility to correct errors (noise and distortion) before they reach your speakers. If you have balanced connections use them, otherwise don't worry about it. Btw, Hosa makes a nice 20 AWG microphone cable with Neutrik XLR's - about $30 per 20 foot pair on sale at music stores. You'll be laughing all the way past the stereo shoppe :-)

Single ended (RCA) cables carry the entire waveform, not just the + or - side of the signal. A balanced (XLR) cable carries the + half on one conductor and the - half on another. This allows for some small reduction in noise picked up by longer cables in that the + and - halves of the signal can be compared and any common noise between them can be summed (cancelled) at the input of the next component. This also applies to a "fully balanced" component. This is only true if the next component's input uses both halves of the signal. On some components where throwing in some XLR jacks is an afterthought, they simply use one leg of the signal. Components can also be balanced. If not, a splitter has to be used to output a balanced signal. My experience is that balanced sounds better on some components and single ended better on others. If you use long interconnects, some small reduction in noise is also possible.
