Ground-Resonance Gold & Platinum 3.5mm/4.4mm 2-Way Type

➖Product Details➖

The Ground-Resonance Gold&Platinum 3.5mm/4.4mm 2WAY type is an audio accessory that connects to the GND line inside the device by attaching it to an unused 3.5mm or 4.4mm terminal of a DAP or DAC. This product also comes with a premium lucky box containing only PWAUDIO's high-grade recables.

Inside digital audio devices, various circuits such as DACs, amplifier circuits, and wireless communication modules operate, generating small high-frequency components and electromagnetic interference on the GND line.
The Ground Resonance series was born from the idea of controlling electrical behavior by connecting through a unique shape/alloy, and then making final adjustments by addressing the GND environment of the audio system. Utilizing the electrical properties such as conductivity and impedance of each material, different tunings are achieved.

The newly developed custom gold-plated alloy plug and custom platinum-plated alloy plug feature a unique structure that can be used with both 3.5mm and 4.4mm PO/LO terminals. Despite their compact size, they are designed to maximize surface area for more effective performance.

【Gold】
◆Tuning that emphasizes rich resonance and musicality◆
Gold, made from a gold-plated alloy, is designed to deliver a thick sound image and rich resonance. It provides a moderate thickness and enveloping texture in the mid-to-low range, emphasizing the expressive power of human voices and acoustic instruments. The high frequencies are smooth and not fatiguing, making it excellent for vocals, jazz, and string-focused music.

【Platinum】
◆Tuning that pursues high transparency and clarity◆
Platinum, made from a platinum-plated alloy, is designed to emphasize information density and spatial expression. With fast transient response and excellent responsiveness, it achieves a clear and open sound. It also excels in high-frequency extension, sense of air, and localization, leading to a sound that makes it easy to grasp the positional relationships of each instrument, even in large orchestras or music with a lot of information.

Ground-Resonance Gold&Platinum is not a product that changes the performance of the DAC or amplifier itself, but rather an accessory developed to pursue the overall playback balance of the system. The manifestation of its effects may vary depending on the equipment used, system configuration, and listening environment, but the more refined the system, the more noticeable the difference may be. Please use it as an accessory to further elevate the quality of your audio experience.

【About the Lucky Box】
The lucky box included with this product is a premium lucky box containing only high-end models, including models that were previously limited editions or models not yet released in Japan.
