We at Bryston, do not think cables should be ‘voiced’ to sound a specific way. The best cable is NO cable at all so we contend that the best cable is the cable that changes the signal the least.
The geometry (where the plus is relative to the minus) of a cable determines the inter-relationship between the measured performance of a specific cable. These measured performance criteria are call the ‘Primary Constants’. They are R-resistance, L- inductance, C- shunt capacitance and G-shunt conductance. You can play around with all types of exotic packaging and add-on appendages you like but ultimately the measured performance (primary constants) tell the tale
The XLR cables we use are also very low in capacitance. Actually the XLR cable we are currently using is in fact low noise balanced microphone cable with 100% shield coverage against RF. The advantage of Balanced XLR cables is that they have a noise canceling effect know as ‘common mode noise reduction’. This helps prevent noise and hum from affecting your system. With today’s complexity of audio and video surround systems this is a big plus, so if you ‘got em-use em’.
