To get much better performance from interconnect cables is to biwire them, both cables must be balanced.
Two pair of balanced cables are connected together into 1 pair in the same xlr plug at both ends in a special configuration.
This configuration cancels out the cables weaknesses and enhance the best in them.
Before the biwiring, it was like that I have listened with many thick curtains in front of me all the time.
The sound don't get a little better, but much better.
This cable configuration design comes from Germany, and are only known by a exclusive small group of people.
This technology will be patented, so I can't tell you the name of the company and how the configuration is done.
