I have a pair of Audeze LCD-X's on the way and am considering amp choices. The ones above are what I'm thinking, but not sure which would pair best. My favourite music genres are 90% rock/classic/alt rock and about 10% pop, classical, etc. I didn't know if the NFB-28 is overkill from the NFB-11 which I've read great things about. I've heard good things for the LCD-X with the Jotunheim too. It should also be noted I'm in Canada, so cross-border duties, etc. usually bite us in the ass, if that's a factor. Open to other choices too.
