What preamp? If it's the least be "hard" on the tubes, the JJ's will be a nightmare. I will agree that they are the best sounding current production, but they have a horrible failure rate if pushed in the slightest.
The EH 6922's are my current production tube of choice in my Bottlehead phono preamp although I prefer some NOS Tesla's from the 70's with some cartriges.
