The # 1 rule for more marginal audio tweaks is always ask "why?". It works in life in general the same way.
There should be some good reason to try anything, especially an expensive piece of technology. Any technical gadget worth its salt is designed a particular way for a specific purpose. If it is not, or if it might be but nobody can tell you why, just move on to clearer waters.
One or two people saying "this is what I heard" is NOT a good reason, even if somehow it could be determined that they did in fact hear what they relate. Its a data point that means something, but relatively little alone in teh big picture. The question is always why does something do what it claims to do. Even an unsubstantiated theory on why is better than nothing, which is what one might end up often getting with this stuff.
If even the maker cannot provide a good answer, then best to just move on until someone can. You'll probably end up in a happier place sooner and for less money.
