I'm using a pair of Beyer DT-990/250s right now. I sold my LCD-2 earlier this year to fund some planar speakers, so the Beyers are currently my go-to cans.
To my ears, with these headphones, the 6922EH that the amp came with sounds thin on the low end. It's got some extension but lacks weight. I find it generally cold-sounding, and pretty harsh in the highs.
For the past few hours I've had an ORTF-selected 1972 RTC PCC85 (Mfg by Philips in Holland) tube in and it sounds very good.
A few other things I've rolled through today that I've liked.
1959 GE (Philips/Holland) D-Getter 6ES8 - Warm without being overly lush, very smooth yet detailed. Beautiful mids.
1965 RCA (Mullard/Blackburn) Large O-Getter 6ES8 - similar to above, a bit more bass, bit more treble extension, a bit warmer.
Tungsram PCC189 - need to spend some more time with this one, initial impression was pretty good.
