jayctoy, thank you for your thoughtful replies and the effort to make the Schroeder Method more visible; I think it helped greatly to introduce it to audiophiles at large.
It would make sense that some combinations (not yet recommended) of blended cables in Schroeder Method might be unsatisfactory to the ears. I have done approximately 9 systems of various config. (RCA, XLR, integrated DAC to amps, preamp to amps, etc.) and am overjoyed at the consistent, powerfully beneficial results.
This is one of the more enjoyable periods of being an audiophile over the past 30+ years. I am beginning to experience the realization of sound quality/experiences I dreamed of but was not sure could ever be realized.
The Benchmark Media DAC3 and AHB2 Amps in Mono are stunningly beautiful in this setup. The Class AAA amplifier technology is breathtakingly beautiful with Schroeder Method. It maximizes the technology Benchmark made in collaboration with THX. The sound is far superior to any rig I established while reviewing them for Dagogo.com. Single IC does not tap into the reservoir of sound quality of these components. (I suspect that to be true universally with any appropriate (note again the "do at your own risk" environment) components, but much more have to be tried to make a general statement of it.)
The Schroeder Method is big, much bigger than I had thought. I think I still don't have a handle on how big it can get.
