Yes, two reasons. First, I could not find my bloody DIN plug. This unit has been sitting here since February so wanted to get it out.Is there a particular reason the amp itself is not measured but just the amp-headphone combined?
Second was the aggravation. I measured the last one as you state. Massive argument broke out that the 200 K impedance of the Audio Precision was too low and was putting too much burden on the amp. I actually showed later using an acoustic test like this that my measurements were correct and the impact there was negligible. Still, I was in no mood to start all that over so decided to just jump to acoustic test which no one can complain about.
If I had found the plug, I was going to build a high voltage voltage divider to create a higher impedance load but per above, I could not.
