COS Engineering S10 Switch: Elevating Network Sound Quality
After a year of dedicated research, Taiwanese brand COS Engineering unveiled its latest offering, the S10 Switch network switch. The COS team, well-versed in high-end audio systems, specializes in DAC and network digital streaming design and boasts Roon Ready certification for their products. Their current flagship, the D10 DAC, offers network streaming and phono-amplifier interfaces, providing users with versatile playback options. The S10’s development took a year of meticulous work, from circuit design to material selection, testing, and modifications. It’s positioned as the final gateway for network signals into network streaming players, emphasizing the importance of maintaining a clean source.
A Sound Investment in Power and Design
The S10 shares the same rigorous power input processing as the D10. It incorporates a meticulously designed AC input module, a toroidal transformer, voltage stabilization, and other procedures. This sophisticated power supply stands out compared to conventional switches and significantly contributes to sound quality. The internal circuit layout is a unique creation by the COS team, emphasizing their technical prowess. Internally, two computing chips manage the two optical fiber transmission terminals and four RJ45 transmission terminals, each equipped with a precise crystal oscillator clock to minimize jitter. The S10 boasts eight RJ45 network terminals and two optical fiber network terminals, with a unique design feature. Unlike most network switches that group four RJ45 terminals, the S10’s eight RJ45 terminals operate independently. This distinct design mitigates interference between terminals, although it’s an internal detail not evident to users. The S10’s usability is further enhanced by its ability to independently turn off unused network terminals. This unusual feature ensures network terminals aren’t continuously active when not in use, which can negatively impact sound quality.
