See my post here for initial impressions.





Left channel shows a fairly flat response from ~20-30Hz up to about 1KHz. There are two fairly pronounced dips centered around 2KHz and 6KHz, and a bit of an emphasis around 3-4KHz.



The 3-4KHz emphasis stands out more that you might think initially, but this is probably explained by the relatively flat bass-through-midrange response and it being surrounded by a dip on either side.



The treble itself doesn't lend much evidence here to suggest additional brightness, despite impressions.



Right channel sounded consistent to me.







Compared to the LCD-2C, the LCD-1 doesn't have quite the same extension below 50Hz, but it's still good. It's certainly brighter around 3-4KHz and possibly around 8-10KHz too. And despite the LCD-1 having its share of response anomalies, it has a more controlled, smoother look overall, whereas the LCD-2C exhibits a more ragged response.







LCD-1 vs HD6XX (stock), just for reference. Not sure I need to add commentary.







CSDs suggest one possible source of treble brightness is the ringing just above 10KHz. This can vary a bit, shifting around the 10KHz point slightly. Sometimes, the ringing is closer to 8KHz, seen in different results that I haven't posted.



It is not particularly unpleasant in and of itself, nor does it stand out. I would have assumed a frequency response issue before ringing. While it's fairly sharp and long-lasting, it may be just low enough to not be too bothersome.



I'm more concerned about the excess energy, or perhaps lack of driver control, in the upper-mids through lower-treble. That 6KHz dip may not necessarily be a hidden peak, but it's possible there's more energy there than FR suggests initially. So, it may or may not be a real cause for concern.







Same thing, but floor lowered from -36dB to -45dB. Far from the cleanest results I've seen...
