Like Bo says: you're hearing the well known Fletcher-Munson curve effect, which is a bell-curve peaking in the midrange area. Your hearing seems quite normal to me too.
Tone changes with volume
Has anyone ever noticed how tonality changes depending on volume setting. I thought it was just me until I saw this review of the LW-1 passive preamp:
LW-1 review
"The X-coupler is designed for a wide range of combinations and can drive amplifier loads as low as 10k ohms. This, in theory, should help reduce the shift in tonal balance that results from the changes in impedance caused by the varying positions of the volume control."
Maybe I'm not crazy after all :-)
