Tube Rolling with the Line Magnetic 518 IA


I recently took delivery of the fine Line Magnetic 518 IA. This is an excellent integrated except it comes with basic inexpensive tubes. I'm lloking to hear from those who have done any tube rolling with this amp and what combination turned out to be the most musical sounding. Also interested in how many hours it took to break in this amplifier.

Hey tnut....did you ever get the Psvane 845WE tubes?  I also have the LM5181 and am now wanting to try some new 845s. And do you think the Psvane 845T II would be a worthy upgrade? Or better value ($400 vs $700)?  Thanks......
@willmacc,  I don't have this amp.  I have a Primaluna Dialogue HP integrated and have tried the Tung Sol 7581A reissue.  I highly recommend them.  I've rolled KT150s, KT88s, EL34s and the 7581as.  The Tung Sol 7581a  is my favorite.  I like the 150s, 88s, and 34s too--each for their own qualities. But my all around choice is the 7581a.
