@fair -- All that typing, and all that work, but not even a minute of research to understand why a resistive load is used for amplifier testing. It took me a bit longer to understand this item. I think I spent almost 30 minutes, but now I am comfortable with the answer. I also know now that everyone uses resistors for testing including Stereophile. Stereophile has a simulated speaker load, but this measurement provides no additional information that cannot be ascertained in other measurements. I quickly found at least 6 and probably there are many more discussions on using complex loads for amplifier testing on ASR. I had to Google to understand some of the terms, but I muddled through. Even the stronger proponents of complex load testing, after the discussion progressed, agreed it was of limited and would only be valuable with an extreme speaker and a marginal amplifier.
I thank you for encouraging me to look into this as I sort of understood it, but had not delved deep enough. It was a less complex topic than I was expecting.
