No Balanced Circuitry

It means the the input/outputs are balanced but that the circuit topology is not fully differential, which would indicate a positive and negative gain stage for each channel. Twice the circuitry which is why most manufacturers don't do it.

Hi Spin,

So does it mean that there is no sound significant sound different?

Twice the circuitry which is why most manufacturers don't do it.

This statement is incorrect. It does not take twice as much circuitry to go differential!

Clarrie, the answer to your question is probably yes. If the circuit is not internally balanced, the chances are very good that the connectors are just there for convenience.
