Yes, had the Edition X for a week from a friend and have the LCD-2 fazor and the HE560. Here is my ears take on them: I prefer he HE-560 slightly above the LCD-2 but must admit that these two are a bit similar. Yes, there is more treble in the HE560 but their bass is going a bit deeper - the LCD-2 has slightly more quantity but driven properly the 560 holds up quite well. I have a feeling that the latest driver revisions could turn the page - I am getting my LCD-2 updated soon and shall report back. Also - the ifi Pro iCAN in tube mode has such a great grip on the LCD-2 I didn't want to put them down. Spectacular good sound. Which made me forget about the Edition X and enjoy the LCD-2 knowing that there is still some quality I have not yet explored. However the Edition-X is a steppe, though I wasn't as sad when I had to return these as I was with the ifi Pro iCAN as this amp made the LCD-2 and the HE560 shine in their best light. Cheers.
