All in all spent around 6 hours with the LCD 4. Though the price of the abyss is very high; the price to performance I heard between them, the 009/007 when next to the LCD 4, made the LCD 4 (to me) not very good from a financial stand point. I certainly don't think they play in the leagues of the electrostats and abyss as per the Audeze site claimed during their release, and agree with many opinions that although they are clearly technically improved over the rest of the range they are not summit-fi at all.
And wearing them for 8 hours? I'd struggle to do that with the most comfortable pair of headphones I've ever used, never mind ones that weigh 1.5lbs.
detail wise, where do you find the lcd4 to sit? Before it seems the lcd3 was at the bottom of the pack for raw detail, but does the lcd4 resolve better than any of the summit-fi cans you can think of
I can answer both of your posts with one answer. I earlier left a review a page or two back, maybe more. I personally find the 007 and 009 lacking as I have felt about all electrostats except the original SR-Omega, hence the reason I don't own any, which I doubt many of you ever heard since it was a limited run. It had better imaging than any phone, ever. But a very loose headband and the phone constantly fell off your head unless you had a huge head.
As far as resolution, I had said I find the LCD-4 to sound like a blend of the best traits of LCD-3, the HD800, the SR009 and 007, and the HE90, and then a perceived doubling of the performance.
And potkettle, which version of the LCD-4 did you hear? Old diaphragm, or new diaphragm? The new diaphragm is a very much improved design, and sounds much better, though it does require a lot more power at only 97dB/mW @ 200 ohms vs. the previous diaphragm at 102dB/mW @ 110 ohms; about 2.3x more power for equivalent volume. Also, a spacer was added between the earcups and ear pads.
I can't find fault with any part of the FR of the LCD4s (at least on my super transparent system), and they are my total end game. I was never satisfied with the 009 even on a DIY T2. They are strident lacking in any form of decent bass response. The 007 (mk1 and mk2) are better as they more neutral sounding but are very wispy in the treble which is a trait of most stats I hate. The SR-Omega had perfect treble and an almost perfect midrange, though lacked in bass response as any stat does however they had better imaging than any headphone made to date (though I haven't heard the Orpheus 2 so I can't compare them). And as far as the Abyss, they were just weird sounding with good balance in some areas but frequency responses that bounced around a lot like some Sony's I remember from the late 90s through early 00s.
Also, the LCD-4 come with a fairly good stock cable better than many after markets I've heard, so that's a plus, too.
