Sorry to bump this thread, although I guess it's really not that old. I have a lyr 2 and I really enjoy it, but I guess I don't have a ton to compare it to except for lower end stuff. I'm a bit new to all these measurements and what they mean, so I'm wondering what gain setting would be appropriate for my headphones. My current cans that I use with this amp are hd650, he500, and lcd2. I've listened and can't tell a huge difference at what seems to be equal volume letters, but the OCD side of me just has to know lol. Thanks in advance!
