I have an open EL-8 with almost a week's burn-in and I feel I can at least give some initial impressions. They have a full bodied sound regardless of whether they're driven by a DAP solo or with a portable amp. With the Cayin C5 they truly come alive - weighty impactful bass (when the music has it), a rich and slightly forward mid with crisp and sparkling highs. With due credit to the C5 their soundstage was wonderfully expansive and airy and everything sounded bold and effortless, you know these are audiophile grade headphones no doubt about it. If they have flaws its that they have a slight tinge of brightness, but its minor and dependent on the music. I recently got a chance to audition the LCD2. I had high hopes for it after all the rave reviews I read on the web. They have a heavy and thick sound, the bass was obviously taking centre stage here, but they sounded closed-in and lacked air, and the treble was like being relegated to the background. I didn't listen to them long so its just a few minute's impression. I had wanted to upgrade to them initially but didn't do so after my brief impression with it. Perhaps they needed better amplication than the C5 could manage, and perhaps a better source than my HM650 as well. I'm a basshead through and through but I would not take great bass at the expense of a subdued treble and a small soundstage (even when driven by the super-airy C5). However I'm tempted to listen to them again, I don't believe they sounded like they did when I heard them. They probably needed a better source, DAC and amp to hear them in their full potential I suspect. Nevertheless, Im surprised that they have such differing sound signature since both came from the same company. Just my two cents' worth.
