Mike, perhaps it was not clear that I tried to indicate in the article the tube output would be the standard in testing. I felt the tube output was overall preferred and that readers would be most interested in it. I would comment upon SS output when I felt it was meritorious.
I realize that the article does not show a comprehensive analysis of all permutations of the Opamps, prices etc. as I state in the article, "Considering Opamps, tubes, solid state or tube output, and the volume setting dozens upon dozens of variations are possible, and you can appreciate that Im not paid to run a lab." Considering that this was an unsolicited article, one I pursued on my own initiative as a service to the community to raise awareness of the activity of Opamp rolling, I secured some Opamps and tested them to see if Opamps make a difference - if that was not good enough, my apologies. If it is helpful, I found in general that the distinction between any given set of Opamps operated in SS/Tube output was less dramatic than comparing entirely different sets of Opamps.
I put in between 35-40 hours of communication with suppliers and manufacturer, setting up systems, testing Opamps and writing/editing. The goal was to introduce Opamp rolling and weigh its efficacy, nothing more. I am disappointed that not one individual from the professional or amateur DIY/Mod community contacted me to warn me of the potential danger of suggesting reversed Opamps. The heads up came from Bill O'Connell of Morningstar, the distributor, and I'm grateful for it.
I have learned information about the situation which has left a negative conclusion in my mind about the incident, but I do not wish to discuss it publicly.
I am finished with the topic. People can make of it as they wish.
