Interestingly, I noticed an unexpected improved low volume listening performance when I switched amp type from an Aragon class AB to a class D amp of about the same wattage. The improvement was significant even though I was using an older pair of Magnepan 2.7QR large panel spkrs that are fairly inefficient (87db @ 1 W).
I'm familiar with 'loudness' controls and would equate the improvement to their affect; a perceived increase in the bass and treble to compensate for the proven reduction in perceived bass and treble when listening at low volumes.
What I found especially noticeable and beneficial with the class D amp performance was that the proper bass and treble presence maintained its proportional accuracy at all volume levels, from soft to very loud as if there was a 'loudness control' continuously engaged.
I cannot verify that all class D amps share this ability, however, I currently own 3 different brands of class D amps (ClassD Audio, Emerald Physics and D-Sonic) and they all share this ability or characteristic.
I would also agree with the several other responses on this thread that stated moderately high efficiency speakers would be beneficial for improved low volume listening performance.
