Good decision, you’ll be covered regarding the 310a for many years. It’ll be interesting when you get around to the 300b driver and the 845 output tubes. I have good experience with both especially the 300b. I’ve heard 11 different brands in my SET amplifier (both my own and via "generous " loans from fellow audiogoners). Good 300bs aren’t cheap but the better ones definitely sound terrific.
Granted I’ve only heard the 300b as the output tube and not functioning as a driver tube as in your amplifier. When it comes to the 845 the Psvane W.E Replica was superb in my friend’s Absolare Passion Signature PSET. We both felt that they surpassed his NOSE RCA 845, subjective of course.
As I’ve said before, you Line Magnetic 219ia deserves the best tubes you can comfortably afford. I’m listening to Miles Davis as I type and I feel as though I can reach out and touch the musicians, so real is the sound. A high quality 300b tube in a good amplifier is just natural and beautiful. I believe you can relate to what I mean. The same is true for the 845 tube.
