The Crystal E-G Limited Edition Ground Box is a high-end model of Crystal E. The exterior is also champagne gold anodized, which is different from the regular silver version. At the same time, it inherits the basic configuration of the limited edition "Crystal E Jtune". The interior uses 8 layers of heterogeneous metal plates and fine sandblasting. By evenly controlling the surface unevenness, it is said that the surface area unevenness can be reduced.
The manufacturer also uses 6 special aluminum electrolytic capacitors installed in the plug-in virtual ground "Crystal Ep", and a special etching process is used on the surface of the conductor to form countless cavities similar to the sponge structure. In addition, the capacitor is installed on a printed circuit board with a double-sided solid pattern layout, which successfully expands the surface area of the conductor, allowing it to successfully reach the company's largest ever 68,000 cm2.
On the other hand, the grounding terminal is also different from the general version. The stainless steel M4 wiring screw used by Crystal E has been upgraded to gold-plated M4 (3-point plate screw), which is said to have more stable conduction performance. There are also two sets of grounding terminals on the floor box, one for connecting audio equipment and the other for users to continue to expand.
The floor box comes with two dedicated grounding wires, "RCA - Y terminal" and "Y terminal - Y terminal", both with a length of 1.2m. In terms of other specifications, the dimensions are 80W x 35H x 111Dmm and the weight is about 830g.
