My 4z's absolutely did and was the principle reason why I sent them back to Audeze. Immediately noticed it and it just never went away. My LCD-4's had no such issues.My 4z do not exhibit any type of sibilance at all over many tens of thousands of listening hours, and many different genres. Using GSX-Mini and DENAFRIPS Ares II though, balanced. Maybe the audio components contributed to the treble issues?
