Just purchased a second-hand pair from a member on here who has contributed to this thread, should be getting them in tomorrow, I'm very excited to see how they sound. Have nothing like a proper chain to drive them quite yet, that's the next project. Will start with the cheaper parts, then progress to the amp. I'm coming from a pair of HD700s that, while somewhat fun and definitely detailed...sort of steal the fun for me. I heard a pair of LCD3Fs out of a Ray Samuels Intruder (balanced of course) last week, and have also heard a newer pair of LCD-Xs out of the Bryston amp. Imaginging that the 4 is the best of both added together seems impossibly good, can't wait to get them on my head. My Mojo will have to do for now, I think next step is possibly an Intruder for portable use and then a full-size amp, maybe someday a higher-end DAC. Will look at picking up a Schiit Wyrd and some decent USB cables for transport from my Mac Pro first.
Side note - I can't describe how much I love the look of the Cocobolo, it's gorgeous. Mine will be ebony, and while I like the way that looks as well, I wish I could somehow swap woods with someone. That Cocobolo is exactly the right color and grain. Too bad we've seen all we're going to see of it.
