This is particularly relevant to cable maximization. Unless you lay out the cables in EXACTLY the same way for each test (within a centimetre or so in some cases), the results WILL be different - maybe better, maybe worse. The proof of that is a case of 'res ipsa'. If moving the cables had little effect, no-one would bother about maximization or the converse. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
