So can I post now that I've heard the LCD-XC and LCD-X as well? (Although in prototype form, not the final production versions.)
Unlike mikemercer and warrenpchi though, I was totally unimpressed by both of them. They were both just more of the Audeze house sound to me without adding anything substantial. Not much to get excited about IMO. Don't get me wrong, I think the Audeze LCD-2 and LCD-3 are good, but I don't think they're particularly great, and I thought the same of the new models too. Although it's possible the production versions sound different/better, I'm not holding my breath for anything groundbreaking personally.
From what you've heard, do the X/XC have significantly different voicings relative to the 2/3's? Because that's the thing that's being boasted by Jude, that the X at least is much more neutral-sounding than the wood Audezes.
