How is the S/N ratio on the HB-1 using sensitive cans like the Sony's? Are you experiencing any tube thrush?
Wrt you query, I've read the Amperex 7189's are a good choice.

ASL HB-1 hybrid headphone buffer - best tubes?
I just got an HB-1 and wondered what kinds of EL84/6BQ5 tubes folks have discovered give the best results with what headphones. I have 63ohm Sony MDR-V6's, and right now I'm using a pair of Sylvania BP, with some Mullard re-issues on the way. Many people like the JJ EL84's; should I try those? Thanks,
Neil
