Hi guys,
I'm having trouble "appreciating" the LCD-X, so I need some help. I bought an open-box (e.g., returned) LCD-X and it's really dark above 2.5kHz, which I can't find report of anywhere. What are the odds that I have a bad unit vs. just not agreeing with the LCD-Xs or planars? Here are the details...
* Playing through TEAC UD-501 and TEAC HA-501. These tend to be on the bassy/warm side of neutral just a bit. I previously thought that no one could possibly call Bur-Brown 179x chips "bright" even if they got a perfect score on the GRE, but then I plugged HD800s in and it was like battery acid poured straight into my ear onto my brain (Oh, don't look at me like you haven't tried it!). So, they're pretty transparent pieces of gear.
* I'm accustomed to HD600s. I seem to be allurgic to anything outside of neutral, as I've found from 30+ years of experience.
* I adore everything from the LCD-Xs up to 1.5 kHz or so, but then it swoops down, much like the HE-400s. Absolutely no air at all, much like a digital remaster where they've tried to noise-suppress.
* These are braided cable, suspension-band, memory foam LCD-Xs, so that seems to mean 2018.
* I've broken them in by playing them on a stand (banana hanger, actually) for about 12 hours, checking them every so often. They've gotten better in the upper mids, but still even EQ doesn't bring back the sense of coherent space I'm used to from Senns.
I'm reminded strongly of owning the HE-400s. I had to mess around with EQ a lot to listen to them, but it never got better and I got rid of them after 6 months or so of trying to let my ears adjust. So, do I just dislike planars, or is it more likely that my unit is just out of spec? A tonal frequency sweep definitely seems to drop about somewhere north of 1.5kHz for a moment, and then a peak around 10kHz. Really strong bass 10-20Hz that then calms down to linearity (by comparison, I hear the HD800 mounting very linearly until you-know-where).Everyone seems to call these "neutral," but I find them far from it.
The swoop down after 1.5k is typical and is part of the LCD-X house sound - don't know about Hifiman. I've done frequency sweeps with my LCD-X and LCD-4, and they all follow that curve to varying degrees.
I don't find it annoying, though - and other headphones that don't dip there feel too 'in my face'. I'd chalk this up to preference, but the rest of your chain may very well be part of the issue. There was a chain I had before that made the LCD-X too bright up around 10 kHz, but my current system sounds pretty balanced. If there are multiple headphones that sound the same to you, I would look into your interconnects/components. Maybe try playing them out of a different system, or even your phone, just as another data point.
