"If that happens with less than 105 db, then its an indication that the system has some sort of odd ordered harmonic generation associated with its operation. A sound pressure level meter might be handy to sort out the actual volume level."
Maybe, but levels louder than 80-85 db (much lower) are often cited as the limits of safe listening without causing damage to ones hearing.
Even if you can go 105db, it may not be such a great idea to do so.
Maybe our hearing works a certain way with certain sensitivities for a reason?
I wonder what happens if one listens to nicely produced music, say a big band with lots of brass and high frequency energy live at 105DB? Is it as comfortable as listening to the no NF tube amp at the same level? Its a fair question, I think.
ANyway, its nice to know if one can go to 105db cleanly in any case. That's a pretty good indicator that you have the headroom needed for good results at more moderate volumes, where excessive loudness should not be an issue.
