I think that you may be worrying about nothing. The boost in that area will be beneficial for you, and any tiny degradation to the overall sound will be miniscule.
McIntosh Integrated MA-12000 Better Use Tone Controls or Wear Hearing Aids
I’ve done my hearing test and tomorrow I return for the big sale. My decision regarding this topic will influence my decision as to which aids to get. My hearing test shows that I dip below normal hearing sensitivity at 2 kHz and am 40dB down by 8 kHZ (the highest frequency tested). The eight band equalizer can be activated and I can alter the 2.5 and 10kHz centered bands. The manual doesn’t mention the slope of the roll off, or boost, but it seems that I can at least increase the 10kHz to somewhat compensate for my hearing loss and then listen without hearing aids on, but what cost am I paying by using the equalizer? I’ve no experience with this topic and would value some feedback.
