A balanced connection has two signals and one ground. The American Standard: Pin 1 is GROUND; Pin 2 is the COLD (negative) out of phase signal; Pin 3 is the HOT (positive) in phase signal. In the European Standard balanced connection, Pin 2 is HOT and Pin 3 is COLD. When mating different brands of equipment it's considered preferable to preserve signal phase, hot to hot and cold to cold.
Th outputs of some balanced circuits boast a summing of the balanced signals when they are operated with a single ended RCA connection. Others simply disconnect one phase.
Other than its noise cancelling properties, some listeners report a more 'floaty' quality to the sound of a balanced setup. DAC's and preamps often offer double the voltage output when balanced compared to single ended. Using a balanced DAC can result in a lot of 'free gain' for a preamp but can also limit the range of a preamp's volume control. Let your ears and pocketbook be your guide.
