Yes this may happen. The A121 has a capacitor which prevents this
selfresonace at inaudible high frequencies. But on the other hand this
capacitor causes the Highpassfilter to be something more like a kind of
Bandpass with 12dB/Oct at the "lower side" and 6dB/Oct on the "upper side"
at 5 or 6 octaves higher Frequency.

> anybody know if is this harmful?  
No.

> either way, anybody know more about possibly harmful patches?
Yes there are: Have a look at these adapters:
