The LCD-X manages to be a darker-sounding headphone and, yet, it still has superb treble (i.e., extended, yet never harsh). This is quite a feat for Audeze to have accomplished, since most of the time the end result with a darker sounding headphone is veil (e.g., HD650) or rolled off treble (e.g., LCD-2). To managed both at the same time is simply a coup, which is one of the reasons I consider them to be the best in my collection.
When I read descriptions like this it nudges me closer and closer to placing the order.
I had the drivers in my LCD-2 replaced a month ago and things have never been the same. I had rev.1 drivers so of course they had to replace them with rev.2 and the magic just isn't there anymore. I'm probably going to try out the X to see if it's to my liking. If not, I'll just have to hopefully find a lightly used pair of rev.1s on the market.
