Review by ChingYi Hsu, Editor of Prime AV magazine

The entire content is excerpted from Hsu, ChingYi (2022). Audio Art magazine No. 403, p. 122 At editor-in-chief's home, through the utilization of 9 songs belong to different types of music genres, I examine the impact of this Chronos Optimizer before and after its implementation. Due to the expansive audio system's capacity to unleash formidable sonic energy and deliver exceptional sound quality, I observed a noticeable disparity in my auditory experience before and after employing this Chronos Optimizer, particularly when comparing with the audio equipments in the office room(, the bookshelf speakers paired with an integrated amplifier).

My impression is that the efficacy of this Chronos Optimizer lies not in augmenting the sense of energy for some specific frequency ranges, but has the remarkable ability to refine and enhance the already exceptional sound, imbuing it with even greater intricacy and finesse. For instance, when listening chamber musics, once this Chronos Optimizer was plugged, I hear the sound with a heightened clarity and the richness of the tone produced by the brass instruments is increased. I can hear more precise spatial localization of the thunderous timpani in the John Williams’ film scores, and the vocal performance became more cohesive.

When hearing various songs with this Chronos Optimizer, I find out that the optimization of sound primarily revolves around enhancing the intricacies of the music. It doesn't transform the music you hear in a dramatic and turbulent manner, akin to changing cables. Instead, it elevates the already excellent sound quality, refining the sound further. Therefore, I believe that if you are to invest in this product, both the performance of your Hi-End audio system and your tuning skills need to meet a certain level of proficiency. Because this product belongs to the kind of unique audio accessory that can enhance good sound but cannot help to resolve the problem existing in a bad audio system.
