I had a lot of trouble measuring these to get consistent result for distortion. Saying this for full disclosure. I was eventually able to get consistent and repeatable distortion figures toward the last few days I had this unit. It was on loan from @ChaChaRealSmooth. I do think the measurements reflect certain things that I heard. I'll get into that a bit later. Audeze LCD-3 2019 Frequency Response SBAF compensation. Vertical line across approximates perceptual neutral. Audeze LCD-3 2019 Traditional Harmonic Distortion Plots Audeze LCD-3 2019 Alternative Harmonic Distortion Plots In regards to how they the sound, compared the LCD-2C that was purchased a while back: more resolving, but lower quality lows. There has been talk for years about the consistency of Audeze headphones. I'm not sure Audeze as totally ironed out the issues.
