Background Back in the time when I purchased LCD-X 2021 (henceforth abbreviated as X; similarly LCD-XC 2021 will be shortened to XC in my posts) early this year, I was hesitating between X and XC until the final moment to hit the order submit button. My assumption was X could be better in tonality (I favor open-back LCD tonality) but XC might be more practical for office uses. The pandemic and work-at-home situations seem to prolong, thus I went for X in the end. Months later, I came across RD’s findings on XC’s characters over previous Audeze products. A few of them might be persistent with Audeze’s closed-back LCDs, but I feel like there’s some voicing changes in XC, which made me jump into the loaner tour lately. I know the likelihood to purchase XC for myself is extremely low for now because of their weights, but I want to find out XC’s voicing and technical capabilities myself.
