Just got mine yesterday!! Still burning in (~60h), but like Icenine2, I can't help but cheat and listen while the LF burns in. I'm also using a W4S DAC2, Pure Music, and the LCD2s (rev 1), and even though the LF is still early in its burn-in process I can already tell that this amp is amazing. I had been using the Lyr, which I still think is a great amp, but the LF is already SO much more clear, fast, and real/live sounding. With the Lyr, I'd always thought that the LCD2s sounded a bit closed-in, but somehow the LF really does make the music feel like it is playing around you, not so much inside your head (at least as far as that is possible when using headphones). So far I've tried listening to some Miles Davis, DJ Shadow, Mogwai, Tom Petty, Young Jeezy, and Pink Floyd, and they all sound incredible with the LF. The only thing I feel is missing is a little more bass depth and punch, but its sounds like this will improve as the LF burns in more. I'll post some more after I reach 150h.
