I made this offer because I know how Sistrum works.I know how to make Sistrum work properly if I am allowed the time and space within one's system to set up Sistrum in a complete and orderly fashion..I know by years of experience and experimentation that my system is set up properly with Sistrum in use. I look forward to trying, testing, comparing, documenting, reporting, in concert with a few individuals in the local community of audio any and all so called isolation devices..I want to know more and to learn more..Tom
