That all is pretty darn speculative, IMHO. I keep a decibel meter by my listening position at home. For me 70 dB average for music in the home at the listening position for any reasonable period of time is definitely a little uncomfortable. Over 90 dB at home at the listening position for me is ridiculous, even for peaks. That’s either a weighted or c weighted. And we don’t know how the Pioneer handled peaks. The test was over 40 years ago. We’ve picked it apart to death. It’s not the be all and end all but it had a lot going for it and it is one piece of important information. And again, who cares? Time to move on to other stuff, maybe less than 40 years old, IMHO. And to change the focus of the thread to testing and away from wild speculation.
