Nad 3020 series. I have the 'i' model and it is stellar with the HD800's. Warm and organic yet detailed without any hardness. Loads of voltage swing and always sounds effortless. Always needs a good warm up period though.
I second this. I was once sold a NAD1020 preamp to use as a headphone amp, which is the preamp section of the 3020 (or the 3020 with the power amp ripped out , which is pretty much what NAD did). The dealer told me it would make a surprisingly good headphone amp for the new HD540's I just bought from him. He wasn't kidding, that thing sounded great! Velvety yet very detailed. The dealer was kind enough to make a photocopy of the 1020 schematics. I roughly used that as a basis for designing & building my own headphone amp, which I have used for the last 20 years. That competes really remarkably well when set against my Lehmann Linear headphone amp, both when using the Hd540 as well as the HD800! I like to think a bit of the NAD1020 magic rubbed off on it.
The lower priced one box bakoon sca 7512 looks interesting...not much review/user experience out there on it though.. at least at the time of. this posting.

I've found the (quite new) Sony TA-A1ES amplifier to have an excellent headphone output. Tried it with different cans, sounded great on most. I especially liked the combination with the HiFiMan HE400. The TA-A1 is also one of the few amps in this category that has an selection switch for different impedances (three positions, low-mid-high, which Sony told me translates to 8, 150 or 300 ohm).
The Symphonic line Kraftwerk MK 2 Special Selection is the very best integrated/headphones amplifier to date !!! I have adopted it for my HP2is, better than two box dedicated amplifier i have built for them.
The Kraftwerk has the output headphones on the back and has two separated power supplay, one for each stage, so you have a two box headphone amplifier.
Best!
