The overall portrayal of the QDC V3's three frequency ranges exhibits a relatively well-balanced distribution. In the realm of low frequencies, enhancements have been made to the bass's flexibility and allure, introducing a deeper sense of reverberation. The drumhead elasticity in the bass drum appears slightly tighter compared to the original cable, with energy intensity remaining relatively consistent post-enhancement. Where the original might interpret the bass drum as a single entity, the upgraded cable likens the experience more to an ensemble performance. The original cable offers clearer line definition, with LIMITED showcasing increased reverberation and a more comfortable charm in the bass, resulting in a less distinct, more atmospherically rich sound. While the high frequencies haven't notably improved, they have undergone a subtle transformation in tonality. Given the already commendable high frequency performance of the V3, characterized by clear extension and brightness, it falls within the brighter high frequency spectrum. Notable changes in LIMITED include the refinement of the high frequencies for a smoother presentation and an overall enhancement in dynamics. In genres like Chinese Zither music, the original cable delivers a bright rather than dull sound, while LIMITED brings forth a noticeable increase in sound glossiness. A slight limitation may arise in songs featuring soprano vocals, like "O mio babbino caro," presenting a ceiling in the sound and a lack of extreme high-range extension. However, addressing this challenge may require more than just a cable upgrade.
   The PWaudio cable excels in showcasing the rich mid-range sound it offers. Listening to Jacky Cheung's "She Came to My Concert" beautifully highlights his captivating baritone voice, easily evoking emotions in the listener. The V3's vocals are positioned relatively close, and with LIMITED, there's a noticeable enhancement in the density and thickness of vocals, resulting in clear imaging that elevates the already intimate sound to a more captivating level. Immersion becomes effortless, with the vocals acting as a shield of armor for the V3, while the slight warmth of LIMITED adds a touch of luxury to this shielding. The three frequency ranges of the V3 paired with LIMITED now exude a smoother texture, marked by enhanced smoothness, particularly noticeable in male vocal-centric songs from the early 2000s, such as those from Jacky Cheung and Jeff Chang. Female vocals also benefit from the subtly pleasing and lush timbre, maintaining V3's strong performance across various vocal ranges. In the realm of the V3, if vocals represent its strength, then the weakness lies in its soundstage. Positioned primarily as an in-ear monitor for vocal performance, the soundstage of the V3 with LIMITED remains somewhat constrained. For instance, the distinct sounds of applause and cheering at the onset of California Hotel reveal a subtly narrow soundstage. Even when handling larger symphonies, the alterations in the soundstage induced by the upgraded cable are minimal, if not marginally negative, as the V3 already boasts a well-defined spatial presentation. The upgraded cable introduces additional charm and harmonics, leading to a subtly congested soundstage, which, while enhancing charm, also slightly compromises resolution. This translates to a nuanced reduction in crispness, with a more interconnected web of sounds, rather than a muddled effect. LIMITED's distinctive sound signature comes to the forefront, imbuing a touch of emotion into the V3's three frequency ranges. This influence enhances the V3's already strong vocals, further solidifying their presence as a standout aspect.
