I did finally have the time to listen tomy phones
. I listened to the LCDX side by side with the DX2000 last night. My gears are M3 amp (quite expensive part compared to the other M3s around), NOS DAC (DIY Non Oversampling DAC) and some decent price interconnect and power cords. The system was built around the LCDX. (for example,the hd800 and a lot of cans sound bad with my system). The sound of my LCDX with this system is a lot better to my ear than the sound out of dac amp such as Chord Hugo. I have to write down this information in order to inform what were the DX2000 compared to. About me, I like dark headphones with big bass and soundstage. I am quite treble sensitive (I think) and My impression is below:
I think in some genres the DX2000 hold themselves against the LCDX well. Female vocal,acoustic and a lot of pop and RNB songs sound good with the DX2000. Rock, metal are not the best genres to listen with them though.
I think the bass and the Mid (vocal) of the Dx2000 can satisfy me even though these are still behind the bass and the mid of the LCDX. About the bass, the impact, the body and deep bass are there. When I listen to some edm songs (especially vocal deep house), I dont feel the DX2000 lack anything in the bass department (and the vocal). But the LCDX's bass is just fuller,deeper and more subwoofer like than the DX2000 bass, but compared DX2000 bass to something else such as Beyer T5P Gen2, you can easily see why people call the DX2000 (DX1000) basshead cans.
The Mid of DX2000 is nice,clear and forward (and kind of color). When I listen to a female Vocal song with not many instruments, I dont feel it lacks much compared to the LCDX. The LCDX just sound clearer, smoother, with more detail, but the DX2000 mid is not far behind.
The next point is treble (and maybe the upper mid), I think this point is one of the weak points of the DX2000. I've heard an unpleasant high pitch in some songs (most often when listening to pop- and indy songs). It's funny that this happen with the warm sounding headphones such as Dx2000. The treble is not as good as the LCDX treble. With LCDX you can hear a crystal clear sound without the harsh treble , you hear from the DX2000 (not always harsh though) By the way, I think many of the DX1000,2000 owners already fix this problem with appropriate amps or just upgrade the cable.
About the soundstage, both LCDX and DX2000 have a decent soundstage size. The width and the height is not much different, even though I think the LCDX offer more width and height, but due to the thicker sound of the LCDX, people can feel that the size is not much different (even can feel that the Dx2000 is airrier). The things that make the LCDX clearly superior to the DX2000 are the soundstage depth and instruments separation. There is no contest here, With the LCDX, it's quite easy to tell where the instruments are and if you listen to a good recorded song, you can even tell how far are this and that instruments from you.
About some other things, The LCDX provide a better PRat and the DX2000 is OK in this department. Both cans offer coherent music reproduction, both are lush and fun to listen to. The one thing besides the soundstage depth and instruments separation that make the LCDX better headphones than the DX2000 is the detail retrieval. When I listen to the LCDX, I've heard something that cannot be heard from the DX2000. It s like you compared the iems with 10 Ba driver with the 6 ba driver iems. If you used to listen to K10 and ES5, you'll easily see my point. I think this point is a very important factor, when listening to rock and metal (together with the PRaT). I would say I enjoy the LCDX far more than the DX2000 in those genres. With the LCDX, you feel like you listen to the engine sound of the 1500CC Big Bike , but with the DX2000 the bike is somewhat smaller (500 CC maybe)
Final thought, I think the price of the DX1000 (I dont mention the Dx2000 here) today is ok (700$ I guess), they still sound good compared to something around their current price and not that bad compared to something that cost a lot more than them. It is just a matter of preference, some may find some headphones in this price range sound better, some may find they like dx1000 the most. To me, I like the Dx1000 a lot, maybe I just like the JVC house sound or a woody coloration (for reference, I sold a lot of TOTLs iems just to stop by the woody JVC FW01). The Dx1000 used to be my most favorite can, but today I prefer the LCDX to them.
