Not be heretic about it but our ears do not have flat frequency response to start with, hear differently at different volumes, and become less sensitive over time as noted. So digital signal processing or equalization may be all the doctor ordered to provide any needed corrections.
See the chart to the right in particular in this very informative Interactive Music Frequency Response Chart . Take not of what instruments produce sound at what frequencies and how that relates to teh sensitivity of our ears in the chart. It will help to get a handle on things better perhaps before taking any action, if needed.
Gear that sounded good when younger probably is still sounding equally if in good operating condition. So you can change gear or do some basic equalization/signal processing to correct the problem. Many ways to skin the cat.
