All audio electronic devices offer a fixed HPF & LPF embedded in the circuitry, which the end user has no control over. There is no standard where the settings should be so the manufacture can configure it where they feel is best.

Unless the device offers a hard bypass (which means you can literally plug the unit out of the AC receptacle and you will still hear sound) switch, the fixed HPF & LPF are contributing to the sound once the unit is within the audio chain in bypass mode.

This is why having multiple units between the CD Player/Turntable (Mixer, Equaliser & so forth) and the amplifier will sound different in bypassed (flat position) mode than, connecting the CD Player/Turntable directly to the amplifier.
