KOJO Technology's Crystal E: Elevating Sound Quality with Innovative Design

KOJO Technology is a pioneering Japanese brand recognized for its innovative ground box products. The Crystal E model builds upon the successful design of the Force barEP, meticulously re-evaluating materials, internal structures, and shell designs to elevate sound quality to unprecedented levels.

Enhanced Design and Performance

The Crystal E features a multi-layer dissimilar metal structure akin to the Force barEP. Its redesigned shape has significantly increased the grounding surface area by 1.75 times, resulting in superior performance. This new design not only expands the surface area of each metal layer but also incorporates 0.5mm gaps between the layers, resembling a heat sink structure. The upgrade from six layers (copper/brass/copper/brass/copper/steel) to eight layers (stainless steel/brass/copper) allows the compact Crystal E to achieve a larger grounding area than its predecessor.

Improved Materials for Superior Stability

The housing material has undergone substantial enhancements. While the Force barEP utilized a 2mm stainless steel top cover and a 1.5mm aluminum bottom plate, the Crystal E now boasts a 2mm aluminum top cover and a 2mm steel bottom plate. This low center of gravity design increases stability, further enhancing sound quality.

Versatile Grounding Connections

The Crystal E is equipped with M4-inch stainless steel screws for securely fixing the ground wire of the Y-shaped plug, easily connected with a standard Phillips screwdriver. It features two ground terminals, allowing for connections to audio equipment and the option to link an additional Crystal E in series for improved performance.

Focused Functionality

Prioritizing the floor box function, the Crystal E eliminates the extraneous features of the Force barEP. The redesigned structure emphasizes a low-center multi-layer alien metal configuration, maximizing the effectiveness of the grounding box.

Included Accessories

The Crystal E comes with two 1.2-meter ground wires: one RCA-Y plug and one Y-Y plug. Both utilize high-quality coaxial cables with gold-plated plugs.

RCA-Y plug: Ideal for connecting audio equipment with analog input/output terminals, such as amplifiers, to vacant RCA terminals.

Y-Y plug: Designed for equipment without vacant RCA terminals or those with GND terminals.

Experimenting with different connection methods is recommended for optimal results.

Cost-Effective Innovation

The Crystal E series aims to enhance sound quality while maintaining affordability. By streamlining features and focusing on essential functions, KOJO Technology has managed to reduce production costs without compromising quality.

Sound Quality Enhancement

Users can expect a significant reduction in signal noise, resulting in a darker, quieter background. The mid-range and low-frequency sounds become fuller and richer, with improved analytical power and clearer sound contours. Whether enjoying classical music or lively jazz, rock, and pop, the Crystal E delivers a vivid listening experience.

Aesthetic Appeal

The design philosophy of the Crystal series emphasizes clarity, elegance, and transparency. The refined silver-white matte finish of the Crystal E contrasts with the more rigid Force bar series, presenting a sophisticated appearance. The uniform color on the sides and bottom cover, along with the seamless integration of the curved surface treatment, enhances its visual appeal.

User-Friendly Design

The product model is elegantly printed on the top cover in a sleek font, while the grounding connection instructions ("FROM EQUIPMENT" and "ADD E") are clearly displayed for user convenience, embodying KOJO's commitment to "Creative Power Accessories."
