■ The structure and wiring of the conventional product have been reviewed and upgraded. This has further improved the sound image, depth, and sound field. We are confident that you will be satisfied with the results. ■ Virtual earth products are being evaluated by various companies in audio magazines, etc. However, the current price is quite high (tens of thousands of yen or more). This self-made product has the ability to improve sound quality, approaching that of the Yukimu PNA-RCA01 (¥49,500) - see reference photos (in our subjective opinion). It is a great value to obtain this at this price. ■ We have repeatedly conducted thorough comparative listening tests and reviewed the capacitor capacity, brand, resistor brand, and structural wiring. This is a new gold-plated RCA plug type. Significant improvement can be achieved by installing one in each device. While one per device is effective, inserting them into multiple devices will produce a synergistic effect. ◆ Simply insert it into the RCA terminals of audio equipment such as amplifiers, CD players, and D/A converters. Do not insert it into the REC terminals. ◆ The sound quality improves by removing noise from the extra ground section, which improves the S/N ratio and clarity of the sound, and improves the resolution. In addition, the sound image becomes clearer, and instruments and vocals are expressed very naturally, enhancing the space and sound field, and clearly depicting the music's perspective and background. It demonstrates the power of Yukimu's super audio. ● Diameter: Approximately 2 cm, Height: Approximately 10 cm, Weight: Approximately 20 g
