Alright, I ended up getting my LCD-X 2021. Oh man, this is a stunning headphone. I will start here by saying that this headphone definitely has a burn in period. I have about 8 hours use on it so far, and the sound continues to develop. Once you put a bit of EQ on it, the sound quality is just spectacular. Where do I even start ? The build quality on this headphone is stellar. Upon removing it from the box, there is an immediate new car smell. As I am typing this and listening to music, the gorgeous smell is still there. In terms of weight, maybe I am in the minority, but I don't find it to be an issue at all. I find the LCD-X to be incredibly comfortable, and it fits my head like a glove. Thankfully, my ears don't touch the fazors. I have a bit larger than average ears, so this was definitely a concern I had going in.
In terms of sound, once an EQ is put on it, this is exactly what I was looking for as an upgrade from my DT 1990 Pro. Bass is tight, quick, and has excellent decay and detail. Soundstage on this headphone is honestly not as intimate as many reviews suggest. It is not huge, but I have seen quite a few reviews claim it is lacking this area. I just don't agree with that assessment. Granted, I do own the Gustard X16 DAC, which is well known for having a rather large soundstage. The soundstage on the LCD-X is the same size in width as my DT 1990, but in terms of height, the LCD-X is definitely taller. The LCD-X is also greater in terms of depth. This headphone loves to present everything that is often hidden within a recording, which is just what the DT 1990 also tries to do as well. There is a difference though. The LCD-X has even better detail retrieval and imaging capabilities, as well as being vastly better in its ability to realistically render every instrument. Much more of the fine details within the music are being exposed on the LCD-X. It is obvious after listening to this headphone for the last several hours why it costs double the price of the DT 1990. The DT 1990 is a headphone that certainly sounds like a headphone, and it is impressive in its own right. The LCD-X has the ability to sound far closer to what a good loudspeaker sounds like. I am currently just working on an EQ, and I will post it here when I am satisfied with the results. This is an awesome headphone.
