It’s very simple to explain how a DAC can "remove" musical content. It’s not that it’s literally removed, but rather that the resolution of one is superior, allowing to hear deeper and wider into the soundstage, thus capturing the extremely minute character of the reflections off the walls of the venue. (I will add that this is simply discussion of the phenomenon, not my conclusion re: these two products.) Without referencing the article I believe that is what is intended, and perhaps was not stated so eloquently. It is a very regular occurrence when using components of different manufacturers. All components vary in not just that respect, but many others.
See what I said about the comparison of the Benchmark DAC3 DX to the BP DAC SE at Dagogo.com
They are substantially different builds, and have substantially different sound characteristics.
Also, feel free to reference the discussion in the Cable forum regarding Doug Schroeder Method Double Interconnects.
Note, please that Border Patrol has indicated that this is NOT a suitable method for its NOS DAC. I have been using it very effectively with the Benchmark DAC3 DX. Note that Benchmark has not officially endorsed Schroeder Method; this is my exploration/research. This is an entirely do at your own risk activity. But, the results are stunning.
If you are tempted to rebut me using theory, know I am not interested in arguing or debating my viewpoint or methods. :)
