Hi, I'm Stefan and new to headphones.
I would like to ask you guys for some advice. I've had an LCD-X 2021 here for about 3 weeks, it's a B stock so it's played a lot of hours I suppose. It sounds super good, I really like these headphones. Inspired by the good reviews of the LCD-XC I also ordered these headphones to test and want to keep one. They arrived last Friday and are brand new. My hope was that they would sound as good as the open LCD-X. But already after 2 songs (Doin' it right, Daft Punk and something with church organ) it was immediately clear, something is missing. The bass is not transparent, does not dissolve so well. No punch compared to the LCD-X. The bass is very restrained. On "Doin' it right" it goes down very low, but the sound resonates for a long time and is below the rest. It's like a kind of reverberation in the low end, but in the positive. This is clearly audible with the LCD-X (and also with the reference speaker system, Genelec 8260, and also with iem's FiiO FD5). I use the RME ADI2 DAC without EQ below 300 Hz.
With the LCX-X I don't boost the bass, only the upper mid and lower treble. With the LCD-XC, I had to use a bass shelf of about 4-6 dB to get a similar sound in the bass as with the LCD-X. But then the overall sound doesn't match. I find this strange, I always thought the burn-in can't be that relevant, but now it's my only hope, because I really want to like and keep the XC. If it doesn't get better, then the LCD-X would be clearly superior imho. That would contradict everything you read, or that the difference between X and XC is so great.
Have been running pink and white noise for more than 40 hours, it is better, but not to an extent that I am happy. Wearing glasses makes no real difference.
I still miss the air between the instruments/layers and find the low frequency drop too fast compared to the X. It sounds like an over-damped diaphragm.
So far I like the X cleary better, it sounds better to my ears. There is much more air between the instruments ... I realise there is a difference in the systems, open vs. closed, but I was hoping it wouldn't be as big with the X and XC. As I'm new to headphones, it's hard for me to describe what I'm hearing correctly, but I hope you can understand my problem.
What are your experiences with the XC/X and the break-in period?
What do you use, pink noise, music, sinus sweeps, low frequency tones? And for how long?
I was hoping 40-50 hours would be enough ....
Greetings and have a nice week, Stefan
FYI, I've already asked similar questions at headphones.com, as there are probably few who have already AB-compared the current X and XC models. So I'll try again here ... Time is running as I have to decide this week ...
