As Mattmiller stated, many try to adjust the sound by using different cables, however, when using Wilson speakers, I must agree with Brf. AFAIK, for at least 20 years, Wilson has always used Transparent Audio cables with their speakers at the shows, and for the internal wiring of the speakers. Obviously, Wilson must think the synergy between the two is perfect. So, it just makes good common sense to use Transparent Audio speaker cables with Wilson speakers. You can always change other parts of the system to alter the character of the sound.
And, I have no affiliation with Transparent Audio.
