Tsushima1, the speaker cables have high impedance so with certain amp/speaker combinations it perhaps may not work out. The issue may not be your Martin Logan's but the amp used as well.
With signal cables such as IC's and digital cables, having high impedance is not an issue so I presume compatibility is better.
