You may be cursed with a similar condition to what I am suffering from. According to the doctor, there are those people (1% of population?) that have hearing so sensitive that it gets damaged very quickly in environment that is still fine for others. I lost most of hearing on my right ear after shooting 7 bullets from a 'riffle' during silly 'defence' training I was forced to undertake in my 20s (of course, we were supplied no hearing protection, real man do not need that).
And a practical advice to ANYBODY: if you think you were subjected to a loud enough noise to cause you problems (either explosive in nature, or semi-constant, like listening to music very loudly, like during concert, or meet), run to you nearby pharmacy, buy some magnesium supplement (over the counter, and cheap), and take it for couple days. It was shown to prevent irreversible hearing loss, even if taken AFTER the exposure. There were some research done on military personnel, where they were involved in training that required a lot of shooting many weeks in a row, and invariably control group lost about 20% of their hearing by the end of the test, but 'magnesium'-doped group had no measurable hearing loss, even if supplement was taken some time after the exposure, and even if taking it in small quantities.
I wish somebody told me this 20 years ago.
Sorry for non-H10-related-OT, but I think this is more important to quality of your music than any amp money can buy.
