Hi Guys, In the interest of headphone science I sent my LCD4 (2019 Version) to Oratory1990 in Vienna to be measured. Here are the results: https://www.dropbox.com/s/nm18lctf4xwh7cg/Audeze LCD-4.pdf?dl=0 Here are some of his thoughts: I have to say, in their stock form I am not a big fan of them. They are very smooth in the treble - too smooth for me, I am definitely missing energy mostly in the 4 kHz range. And the ever-present problem of Audeze headphones: too much energy in the 10 kHz+ range. I played around with EQ a lot and ended up with this setting: https://www.dropbox.com/s/nm18lctf4xwh7cg/Audeze LCD-4.pdf?dl=0 This turns them on their head however - marvellous experience. I do like them a lot with the EQ - they have virtually no distortion so you can do almost anything with the EQ without having to fear an increase of THD. The HD800 is a bit limited in that regard, although the settings that I personally use (1 dB less bass boost than the Harman Target prescribes) make no trouble as the THD is still below the audibility threshold. If I had to decide between the 800S and the -4 (both being EQd) I'd go for the 800S for the following reasons: - less than half the price - lighter weight - more space for my ears (the audeze earpads just ever so slightly touch my pinna) - little difference in sound quality. Both have outstanding balance, immersion and "soundstage". The -4 is maybe slightly less harsh in the upper treble/air band - with EQ. Without EQ I find it to be severely unbalanced in that regard, way too much energy in the 10+ kHz band.
