I've been trying out the LCD-X for a few days now, kudos to the Norwegian Audeze dealer for shipping me a demo pair.
Wow. I've been utterly floored, and I'll place an order tomorrow morning, as I return the demo pair.
I've been trying it out with a number of recordings I know very well; the soundstage is amazingly wide and well defined, resolution is terrific - I've picked up nuances which were new to me in records I've listened to (in a couple of cases, I suspect literally!) thousands of times over the years.
Tom Waits' voice never sounded so much... ...alive before. The bass lines on The Who's 'Live at Leeds' throw a fantastic punch without getting boomy; The Stone Roses' debut I've fallen in love with all over again, and don't even get me started on how great it was to listen to the Dark Side of the Moon with these cans (Are they even 'cans', seeing as they are open?).
Most of all I enjoyed listening to a couple of my Einstürzende Neubauten albums - they certainly give any loudspeakers / headphones a good work-out given the excellent dynamics - what with sheet metal crashing down on concrete floors contrasted with Blixa Bargeld's tender(-ish) vocals and all.
I expect to have a lot of fun with my LCD-X in the years to come. When do I get my fan club membership card? ;)
