The only thing I'd add to all of this (and I think Larry alluded to it earlier), is that, in my estimation, there is no one 'all purpose' solution for all components in a system. The more effective a device is at isolating or decoupling, the more it may change a given component's sound. You can fine tune a system that way, or, after listening to the effect of various devices, decide that 'different' isn't better. Thus, I'd be reluctant to paint an entire system with a broad brush that says "here's an ideal solution for an entire system.' Obviously, if it is possible to try these things at no risk before you invest, you can make that decision for yourself. In that respect, I'm product agnostic- different solutions will have different effects on different components in different systems. And while I appreciate that you are doing your due diligence and research, Saint, there ain't no substitute for listening to it in your system, over a variety of source material, for more than an afternoon.
