The pro audio guys I talked to about the noise on my EQ told me balanced interconnects would only solve the issue if the noise was being introduced from an external source. In other words, there is no benefit from using balanced interconnects unless you are experiencing noise due to your environmental conditions. e.g. power cables parallel to the interconnects.

People who claim improvements for balanced interconnects may have been suffering from just that sort of situation. Or they may be hearing what they want to hear. I have not personally tried it out myself.

The noise from your EQ can easily be solved with an isolation transformer. By using that, you can run unbalanced line very long without worrying about picking up noises.
