vinylshadow, thanks for asking; this is intended as a premium, HiFi activity. I intend it for use on the best systems available. I believe the Method is beneficial for all systems, but in particular I intend it for high end rigs.
I have continued to use my method in a variety of systems with no ill effects, and always very nice improvement in sound quality. Recently, I have been reviewing a premium tube output DAC that responds beautifully to the Schroeder Method of IC Placement.
I have also tried it with yet another set of cables (also under review, and again have success. I have not signed off on use of my method with passively networked cables. I don't much care for them anyway. As prior, until it is demonstrated to be benign to nearly any conceivable system or with particular cables, it is a "do at your own risk" activity. But, again, I have not heard of a single instance of trouble.
