If you are running balanced cables, and
Your balanced system (preamp) supports the 600 ohm standard
then
you will find no audible difference between the Mogami and any other balanced cable, price no object.
Why?
The low impedance balanced line system was specifically devised to eliminate cable artifact, and it works.
Single ended: all bets are off.
Balanced, but does not support the standard: all bets are off.
BTW, to support the 600 ohm aspect of the standard your preamp will have an much lower impedance which will be unchanging from 20Hz to 20KHz.
