Am the only one that is puzzled at that kinda response getting a thumbs up? Even with EQ? Is it because the overall quality if still good?
in my case i don't eq them. Overall tone off this headphones is flat as you would expect from monitor cans and as a amateur guitarist i can say that they are giving uncoloured image of instruments with slightly less "vibe" than Sundara (which is near harman perfect) BUT if you compare them, there are massive differences in resolution, imaging, quality and mass in sound that lcd can produce. F.e. drums are like never heard before, so real and natural sounding. In side to side comparision Sundara are light both in sound and mass, with good tonality for enjoyment of music especialy for the price but everything else is soo much worse. They are not bad, but LCD-X are very very good. Besides, the drivers are mighty good, just check distortion levels, it's not Focal where you pay 3 times plus for different tuning of untunable diver (im just saying Elegia was for 400 USD in USA where in Poland they costs about 1000 USD so basic costs is very very low).
This preferences curves are something like book cover. They look that way because of lack of room resonances so someone decided to add a color to headphone sound for more pleasant characteristic.
