For me: LCD2 Rev1: "Ringing" was very bad, basically intolerable. I wondered how few people mentioned this, in the forums or professional reviews. Sold them.
LCD2 Rev2 (2 different pairs, long story, still have both of them): Ringing gone about 90%, but varies with the CD. On most SACDs, ringing was gone about 95%. Liked them enough to make them my main phones before the LCD3s were introduced.
LCD3s : Ringing even less, almost vanishing, and somehow seems to occur when it does at a higher frequency, so they can sound "bright" in the lower treble, but I deal with this
very effectively by using a notoriously warm power cord that was designed to target digital glare, a Shunyata Anaconda VX, along with a "matching" Anaconda Alpha on my Pinnacle amp,
along with a Brimar 6NS7 tube that Tube Depot recommended. This just about completely cures things, but on some CDs there is an annoying trace. But I can deal with it, nothing is perfect, and the LCD3s are so non-fatiguing and natural
where I can't stop listening that I continue to work on tweaks, including power conditioning.
The ringing can sound like a tuning fork's high pitch tone riding on the top of a vocal at a lower volume level than the main sound, kind of an 'ooooooooooooooooo' sound with a hint of vibration.
I keep thinking that this ringing is the Audeze picking up and illuminating digital glare somehow, because SACDs, which to me are the answer to digititus, with glare eliminated, sound soooooo nice on the LCD3s and Rev2s.
I still have not experienced any veiling I think, unless I compare them to, say HD800s or maybe Grados, which can be just plain piercing or screaming in the wrong setup.
I hope this helps and doesn't just confuse things more.
So the bottom line is, yeah the Audezes have some flaws, but when you target the flaws with upstream changes, they are the best things out there (maybe Stax 009s are better, or bass heavy R10s, or HE90s, but I have not heard these
except for the HE90s long ago; I owned bass light R10s, which were bright, and I like the LCD3s and 2s much better).
