Drew attention to the site on Sub Isolator, but did not find reviews on the forums. I thought about using it on my system.

My system: two Sub's B&W DB1 receive a signal from the Main RCA Classe CP-700 that has no Sub output. Balanced outputs are engaged in Bi-amping.

Will I receive any benefits from the Balanced Sub Isolator? Then I can make a parallel connection of power amplifiers and subwoofers.
