I've had to be way more particular with HD800 tube pairings though. The sort of reckless high frequency mess going on with the teslas was just WAY too hot for the HD800s. I had to roll back to something more balanced. The LCD2s I used to have ran those tubes like a champ, though.
I guess I'm discovering that when it comes to headphones, I'm a serial monogamist. I don't know how to spread my love around to all my headphones.
I love my DT-880s, but even since I got my LCD-2s, I have not had them on my head for more than 10 minutes.
