You can enjoy different music expressions by switching one system to another. These high-grade system selectors are designed for you to taste such charm of audio systems. We introduced the sound-quality-oriented design in which the whole grounded circuit is switched to prevent noise via a ground loop. In these selectors, 6N (99.99997% copper) wire is used for wiring material because information loss is little and high-purity gold-plating type is used for the terminals, which makes the selectors comparable to high-grade separate amplifiers. We have never compromised on the consideration of sound quality.
