I have neither the money nor the patience (well, let's be honest, primarily the money since I'm retired on a fixed income) to roll anywhere near the number of tubes as some of you. I got the LP in May and rolled my first tubes this week--the easily available, not cheap but not too expensive NOS National (Matsushita) 7DJ8. They probably aren't really burned in yet and I'm not particularly good at describing sound. But though they are not night and day from the stock EH 6922s, they seem to sound a bit more smooth and enjoyable. My ZMF Aeolus, which is reasonably well burned in now, sounds terrific.
BTW, I suspect that Monoprice has made some running changes to the tube sockets on the LP. Or I got lucky with mine. After hearing all the horror stories about inserting and removing tubes on the LP, I had no real problem installing the stock tubes, then removing them and inserting the Matsushitas. Though given the limited space to work with, I have not tried tube savers yet or the adapters I used on the Valhalla 2 (which also uses 6922s and variants) for 2C51s and 5670s. If they did not come out with the tube (which they generally did on the Valhalla) I would hate to figure out how to remove them. (And in any case, Dr. Cavalli does not seem to really recommend using adapters for non-6922 variants.)
