Shoulda been a "sometimes" or "depends on the ----" catagory. I use it, and the tone controls, but only when I feel that it enhances the sound, due to the system, enviorment, background noise, whatever the need may be. Low listening levels, I like the loudness button, but not on all my equipment. Different pieces have the "boost" set at different steps, and therefore sound different. Noisy crowded room, I like to set the treble control up a few notches sometimes. The point is, to me, leaving everything flat just isn't the perfect setting for all listening scenarios....
