Which preamp would you sell?

Actually my old Apt Holman has a pretty good headphone amp build in. And it's controls are helpful for headphone listening, too.

That's sweet. I thought it probably did given its age. I have an old Sansui integrated amp with a powerful and clean headphone amp. I have a pair of Grados but I've thought about getting a pair of hard-to-drive Senns to give it a challenge. The Sansui's headphone amp seems to have more power than the ones in my newer gear. What phones do you use with the Apt Holman?
