Loudness Button pro or con?

[Squishman]

For music or anything else with my vintage Marantz system (described below in my sig) should a guy have the loudness button engaged? Obviously it would be my preference, but just wondering what the general consensus is regarding that button. Does it tend to muddy up the sound? I don't hear any difference at my usual listening level. Am I correct to assume it's for lower volume anyway?

Loudness buttons are an abomination and have no place. They boost bass and treble the more you lower the volume. I never used them.
