Any and all low frequency "rumble filters" that I've tried robbed the musical presentation of a solid foundation and much of the life of the music.
Those LF filters were mostly for attenuating the "rumble" or motor noise of idler-driven turntables, and not for taming bad arm/cartridge mismatches, which can affect things (such as tracking) long before the result would reach the speakers.
