Since tried different tubes, cleaning the tubes, making sure they're seated, trying different cables. Nothing. Still noisy as heck. Apparently Leben's explanation for the headphone out (since a lot of people seem to find these amps noisy) is that some are made for more sensitive headphones, while others aren't. Uh... with no indication? What, is it luck of the draw or something?
I've had no noise with the LCDs, HiFiMen, and--oddly enough--the Edition 10. But lots of noise with HD800s, T1s, and the Edition 9. Plus I've also had noise whenever using the speaker taps with a transformer, on both the TakeT and Float QA. So I don't think the issue is related to the headphone out alone.
