Did you get the Line 2 Special Edition? I have this pre and the break-in was extremely long. In my opinion, mine didn't really begin to sound "right" until I had two hundred hours of playing time. And, there were further improvments up to 400 - 500 hours.
It has, IMHO, become an incredibly nice pre. As long as nothing is broken, don't swap any tubes until you have the hours. If you have the Special Edition, the tubes of good quality; I've had no desire to make any changes since I got through the excruciating break-in.
