I had listened to ten or more headphones in 2018 and had gotten the Clears at the time (at a discount), the LCD-Xs having been my second pick. They probably don't want to see me again at that place, and that's ok (it's in Torrance).
LCD-3 still sounds darker than the Clears even when using the Reveal plugin, but their rounded/liquid/warm quality is still appealing. It's my preferred headphone for hard rock and metal.
I think the LCD-4 also has a dark signature, but with more microdetail. Don't think the LCD-4 or the MX4 (that one I had listened to), are particularly competitive these days when you look at all the new $2000 competition that's come out since.
Any song having a lot of instruments below 90 Hz, I had preferred planar headphones. Clears have a resonant peak at some point below 100 Hz (see where the impedance rises on the Tyll Hertsens data sheet), which planars lack. Your bass won't sound as clean at that frequency, and you may get phase shift. When using speakers, 60 Hz doesn't sound great in my room, either, even using an excellent servo enabled sub. I think it's because planar headphones don't have room related nulls, rising distortion, phase shift, or drivers interacting around the crossover frequency (though I cross over above 90 Hz). U2's "Mothers of the Disappeared" from the Joshua Tree album, for example, has a track at that frequency where I couldn't hear the individual notes until I had listened to them with the LCD-3. It had been a blob of sound.
My Martin Logan 60 XT speakers which I had gotten a good price on from Crutchfield, due to them having been returned, and (marketing wise), the old model, outclass the LCD-3s in resolution and imaging (which saddens me, as I had paid less for them than the current LCD-3 MSRP), and sound closer to the Clears (they are lively).
Audeze, doesn't seem to have come up with a new innovative driver technology, that doesn't sound dark.. even if they have, I had already lost interest, not wanting to pay what they charge for their products (the 4Z or the 24, that is). I hadn't been impressed on a personal level with Rosson leaving Audeze and becoming a competitor. I would imagine the Rosson RAD-0 sounds better than the LCD-3 (or he wouldn't have a marketable product). He had probably been arguing with the management (which nobody would admit publicly), before leaving and forming a new company, or else he could have just released the same product at Audeze, and called it a LCD-5, or something.
If I could come to terms with spending over $2000 on headphones, I would probably get the ZMF Verite, or the Meze Empyrean.
I had bought the LCD-3s used from a place in the Denver area, and would probably be selling them for under $1000, having to eat the cost of the Dekoni hybrid pads and the new headband I had bought (about $200). I may reach a point where I decide I can't deal with lugging them around if I move.
Getting a Chinese IEM next week.
The reasons you stated are what ultimately made me choose the Clear over an Audeze. I only tried the LCD-X in a shop years ago so I could not compare the two, but to me the tonal balance of the Clear just outclasses the Audeze house sound. Yes, you may get better bass fullness and impact with an Audeze, but I’m not willing to trade that for the excellent midrange and treble presence of the Clear. I also have a modified HE-500 that gives a lot of bass authority and wide soundstage when I need it. The Clear is the more precise and tonally correct headphone though, even with the occasional treble peaks at 6 and 10 kHz that are easily EQed out. And everything sounds so realistic on the Clear, I have a hard time switching to any of my other headphones.
However, I am curious to try the LCD-2 or 3 someday with the right EQ settings, it may be a nice compliment to the Clear.
