great headphone amplification in vintage gear?

I am currently powering some Denon AH-D7000 headphones with an old Luxman L480 integrated and to my ears, it sounds noticeably better than a dedicated Headphone amp Musical Hall 25! The Luxman has a little more hiss than the MH but only noticeable when music is quiet, still it is so much more musical to my ears!
So I was wondering if there is other vintage preamps, amplifiers, integrated amps or receivers known for having great headphone amplification out there?
Thanks!
