Garfish, I own a Line 1 SE. Kevin Deal at Upscale Audio gave me a great price and I love the unit. I think the 3 matched sets of Siemens tubes alone is worth the increase in price over the Line 1 standard. But there are numerous other serious parts uprgades too.
I don't know how much SF is asking for the upgrade, but it may be smarter to put the Line 2 up in a classified and at a high amount. See what you can get, because the going rate on a new Line 1 SE version will astound you. I can't believe the difference between a Line 1 and Line 2 is significant enough to consider a Line 2 SE. And I'll bet you can get pretty close to the amount needed for a new Line 1 SE from the classified.
