Hey gang - resurrecting this old thread, as a quick update.
I replaced the stock EH 6H30P tubes in my Athena with 6H30P-DRs (purchased from an on-line dealer). When I opened up the preamp, there were no dampers on the tubes as the unit came from Rogue.
The DR's are interesting - the most obvious difference in my system is tighter and more present bass, and they're a little brighter (not what I was expecting actually) - overall very clear and discerning. I haven't listened to any analog through them yet, but with digital sources they sound nice - more pinpointed than the EH's.
For now, I'll say they sound great - but they're certainly not cheap. Hopefully they'll last a good long time.
