[James Tanner - Bryston]

Hi

I think what he means is that some products have 2 separate signal paths from input to output. So the positive half of the waveform and the negative half of the waveform have independent circuits throughout (which doubles the cost).

The only issue with this type of topology is the advantage of the Balanced inputs cancelling noise through common mode rejection is lost.

All Bryston XLR inputs and outputs are fully balanced differential discrete circuits so they take advantage of the noise cancelling of CMR but will have a single signal path (positive and negative signals combined) after the Balanced input till it reaches the Balanced output.
