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.

Just purchased the 518 and only have about 10 hours on it but very impressed with build and sound quality thus far. I went ahead and swapped in NOS Mullard 5AR4 and GE 12ax7s. May swap in NOS GE 6L6GCs after further listening.

Went ahead and swapped in NOS GE 6L6s. To to my ears they, along with the NOS GE 12AX7s and NOS Mullard 5AR4 have taken the sound to another level. Did initially find the GE 6L6s very bright and needed about 8-10 hours to settle in.  My humble opinion is that this is an excellent amp and great value. Driving Daedalus Argos V2s.
