jayctoy, congratulations! Very nice, and motivates me to push into manufactured double interconnect products.
Currently comparing another set of cables' ICs in both RCA and XLR. So far only the RCA tried, but easily passed my Law of Efficacy in regard to Schroeder Method. This setup is from integrated DAC to amps. Both the integrated DAC and amps allow for XLR, so that is next. I anticipate likewise superb results.
This is gaining momentum due to real world applicability. This could become one of the more interesting phenomena to appear in recent years regarding cables.
For those who jump to the end of discussions and do not wish to read previous posts, I repeat the "do at your own risk" nature of the Schroeder Method, and ask that you discuss with your equipment manufacturer. Please do your due diligence.
