True Headphone AMP?

It never really occurred to me but all the Headphone Amps I've seen are really headphone integrated amps, meaning with volume and sometimes source selection.

Has or does anyone make a true headphone amp that you simply attach to your preamps outputs?

Any reason this couldn't be done?

Given that I am heavily invested in my Pre and love it, seems kind of silly to use a headphone amp off the tape output that wouldn't use my pre amp for all the things it does right.

I think most preamps have enough gain to drive headphones but have to high of an output impedance to work. Is there a non active way to drop the impedance down enough to work with headphones?

I think atmasphere preamps can drive headphones from their main outputs. I believe that is because of their low output impedance.

Please correct me if i'm wrong.

Thanks Al.

I figured there was some good reasons that such a device does not exist. I thought there might be some issues but do not have the technical knowledge to know what they would be.

Might make an interesting project. But sounds like it would not work for but one combonation of pre and phones.
