Crystal EpR

Crystal EpT3

Conductor surface area that cannot be imagined from the size

The Crystal Ep is filled with KOJO TECHNOLOGY’s unique ideas and special dedicated capacitors that are responsible for technical elements, expanding and enhancing the GND plane (conductor surface area).

High-purity aluminum foil processed into strips is used for the internal conductor of the special dedicated capacitor, and the apparent surface area is only about 100 cm 2 (10 cm × 10 cm ) ^. Numerous cavities resembling crystalline structures are formed. ^{As a result, these numerous cavities increase the conductor surface area, and an effective area of ​​11,000 cm 2} (110 cm x 100 cm) is secured
inside Crystal Ep .

Compatible with a wide range of terminal shapes

Crystal EpR, the most versatile RCA plug, Crystal EpT3, a φ3.5 stereo mini plug compatible with mobile devices such as DAPs and headphone amplifiers, and Crystal EpB, M4 to M8, banana plugs effective for speaker terminals. A total of 4 models of Y-lug type Crystal EpY that can handle sizes are commercialized at once. Supports a wide range of terminal shapes. In the future, we plan to expand the lineup to support various terminal shapes.

Sustainable specifications without waste

The Crystal Ep series (ground terminal) consists of 3 pieces: plug/main unit/cap, in order to enhance its convenience, expandability, and expandability.
Each has an M5 size male and female screw structure, and since it can be removed, it can be replaced with other plugs.
In addition, by inserting a ground cable (Y-lug type, etc.) including other companies’ products between the plug and the main unit, it is possible to link with other virtual ground products, and it is possible to use and expand existing virtual ground products. .

The Crystal Ep series incorporates even more amazing features, and can be easily expanded by linking two of the same series together. (Refer to Fig.7)
As mentioned above, the conductor surface area per body (ground terminal) is 11,000 cm ² . ^{The surface area is doubled to 22,000 cm 2} (220 cm x 100 cm) by connecting them together .
Also, when connecting, one extra plug and one cap will be left over, but by combining them as shown in the diagram, you can quickly turn them into RCA cap terminals. It not only prevents the loss of parts, but also enables effective use.
This RCA cap looks like a by-product (actually intentional), but if the audio equipment you are using does not have a GND terminal, just connect this RCA cap to the RCA empty terminal, and that terminal will be GND. becomes a terminal.
This RCA cap terminal can also be connected to a Y-lug, and can be used continuously by connecting other virtual ground products via a ground cable.
The Crystal Ep series, which can be used widely without waste, can be said to be a sustainable product that matches the coming era.

Sound quality trend

Can you see the improvement effect (auditory S/N) brought by Crystal Ep? ear? There is something to watch out for. It goes without saying that even small and delicate sounds can be heard. The left and right spread, height, and depth of the sound field are increased, and the center localization of vocals, etc. is solid. It is rushing into the zone beyond the domain of 2ch (stereo).

design

The Crystal series, which includes our power tap group, is designed with the concept of clarity and delicacy, as the name suggests.
Among them, the Crystal Ep series (ground terminal) was devised based on the diameter of a general RCA plug in order to have a functional and beautiful design. It has a very slim and stylish shape and two-tone gold/nickel-plated color, and the model name and brand trademark are designed with a white silk print to keep it understated.
All parts consisting of 3 pieces are machined brass specifications. This also achieves a vibration suppression effect at the same time.
The various plugs are gold-plated for reliability and performance, and the virtual earth part body and cap are satin-finished by sandblasting to expand the effective surface area of ​​the metal conductor and integrate it with the design.
