Hey, hey,
I remember the Apt/Holman! I'm still a fan of full function preamps (I have a CAT Ultimate that has a really nice high gain phono stage).
There were a few preamps with good headphone outputs but unfortunately the newer ones are lucky to have any headphone outs. A couple of really top notch preamp/headphone amps were the Melos and Sonic Frontiers unit's. The Melos units aren't the most reliable but when their working, they're one of the best for driving Grados. The Sonic Frontiers top models outsourced the headphone amp design and really only shared the power supply with the preamp functions.
I recall that a few members here had some preamps with built in tape head inputs (HK Citations). I don't think that any of them ever checked back in to tell us how the sound was.
