Tape-in and Tape-out ports

Why do so many preamp manufacturers still provide Tape-in and Tape-out ports? I doubt if they expect folks use them for hooking up a tape player. Some even still have a tape monitor switch on the front panel. How do you guys use these ports and has anyone noticed a difference in sound quality if the tape-in port is used for something else like a CD player, etc.? If the tape-out port is just like another output, e.g., drive a separate amp or a powered subwoofer, etc., why not just call it Output?
Been meaning to ask this question, albeit it might sound rudimentary.

Me too Don, for my Stax headphone amp. The old tube version of the amp had a pair of output jacks, for returning the signal to the pre.

kalali---For one thing, the tape out jacks are fixed in level, not variable like the mains, so they can’t be used to feed a power amp (unless your amp has level pots). Also, they are taken from before the final stage of amplification in a pre, and their output impedance is often different from that of the mains.

But as cleeds said, those outputs are also used as the source for digital recorders, as well as surround sound processors and digital room correction devices (DSPeaker Anti-Mode, for instance).
