Power LED and Power Button Signal
Teflon-coated silver plated wires are suitable for the connection of electrical equipment and instrument lines under high temperature conditions and high voltage up to 600V. It features resistance to high temperature, aging, acid and alkali, moisture, water, oil, corrosion, and is flame retardant and other properties.
SATA Power Wires
Take a look at the photo of the wires above. In the ordinary copper wire at upper side: The copper wire crystal is irregularly crystallized, and the conductivity is poor. As a result, it generates more electrical noise while power loading varies during system is accessing SSD.
The Rhein Z1 uses OFC copper wire as SATA power wires: The copper wire crystal is evenly distributed by the high temperature, hot casting, continuous casting method, and the current conduction is good and introduces less electrical noise while power loading varies during system is accessing SSD.
The server grade SATA cable is optimized to ensure the stability of the signal transmission. The irregular distribution of the SATA cable in the foam layer generates an irregular telecommunications magnetic field, which affects the signal transmission quality. It also uses durable SATA connectors at both ends to ensure the best connectivity quality.
The special designed exclusive audio SSD features fast access speed, low power consumption, good anti-noise, and stronger anti-interference. It effectively ensures the stability of the output signal, better output data stability, introduces totally different listening enjoyment and experience for you, and brings more fidelity to music.
Built-in Exclusive Audio SSD
Efficient VitOS Operating System
The Rhein Z1 features a VitOS operating system designed for music servers that focuses on streaming services. VitOS improves machine efficiency, performance stability and network latency issues.

VitOS Music Server Performance Comparison
Test method: Play the same music track, captures network packets on Roon player and analyze the latency of response packets to and from Roon server. Then analyze the Roon server response packet latency and compare the result between different systems.
Lower latency implies better music server performance.

DSD Support：Please noted that DAC supports DSD with "DSD Native" is required for you to play DSD music up to DSD256 smoothly. If your DAC supports DSD with "DoP" (DSD over PCM) mode, then the Rhein Z1 only support DSD music up to DSD64 (which means DSD128 or DSD256 is not supported in DoP mode).
