Finally back to the LCD2C after a few rounds elsewhere. Selling and rebuying (which wasn't my initial purpose). They might not be the most natural and spacious sounding headphones out there, but man they are fun to listen to. This bass is highly addictive especially if your music, like mine, requires high quality bass. One user not long ago stated that his second LCD2C sounds different and is more resolving. Apart from the new warranty on my new unit I was curious to hear if there is any difference compared to my previous 2C. Well, there isn't much. I find the main differences in build. The leather strap now has a bigger distance from the metal strap. On my old unit the leather had touched the metal from day one. This is also obvious from the slide settings I use. On my old 2C I used the setting one before the last one. On my new 2C I have to use the last setting. Apart from this I can't feel any difference in comfort. The leather touching the metal didn't make it uncomfortable to me, it is the exact same feeling. Also, the slide moves easier on the new pair. The pads feel a bit different too, but that might be just because they are new. Sound-wise I can't hear a difference. I would say the new pair sounds a bit 'raw', but I am not sure. Audeze said, the film in the transducers loosen a bit by time and that makes a little rattle noise which is normal. I can't hear any noise on my new pair yet, so that might mean the sound will change a little bit too. I expect the 'rawness' to go and a little increase in coherency and smoothness.
