Music Server of Craftmanship
Focus on extracting and purifying the essence of music
Feel the essence of digital music, let the music fully restore the live effect and make you be on the scene!
Custom Built Motherboard for Audio
Customized and dedicated motherboard for audio usage. Low noise for high quality music playback, shortest data path make the smoother and more pure data transmission possible. It consumes less power and introduces less noise on power rails to ensure more stable USB and network signals. The independent USB AUDIO dedicated circuit makes USB AUDIO processing isolated and gets less interference. As a result, data transmission is more stable, and jitter during data transmission is reduced.
Ultra Low CPU Power Consumption
The intel mobile series CPU consumes ultra low power consumption (as low as 6W) to reduce electrical noise from CPU and make the signal inside Rhein Z1 to be more stable and prevent from affecting audio device nearby.
Over Designed Power board
Customized and over-designed power board, which is capable of 160W output while Rhein Z1 only requires 40W, provides sufficient power to the motherboard and SSD and ensures stable data transmission.
High Quality Chassis made of Aerospace Industrial Grade Aluminum Alloy with CNC Processing
Compact and ingenious industrial design make Rhein Z1 an artwork. Fan-less design makes no mechanical noise. Rhein Z1 appearance obtained Chinese patent certification.
Patented Structure Design
The groove structure design has the feature of reducing signal interference, standardizing the line direction and placement. The design has obtained Chinese patent certification.
Patent Certificate Of China
High Permeability EMI Absorber
Furthermore, to eliminate high frequency electrical noise from digital circuits, Rhein Z1 uses specially chosen EMI absorber at the inner side of bottom case to absorb EMI noise from internal digital circuit including DRAM, CPU, …, and so on.
Silent Angel Select
High Quality Cable and Wires
To get more stable signal and get less electrical noise emission during signal and power transmission, Rhein Z1 used carefully chosen high quality cable and wires in power button signal, power LED signal, SATA power and SATA signal.
• Power LED and Power Button Signal
Teflon coated silver plated wires is suitable for the connection of electrical equipment and instrument lines under high temperature conditions and high voltage up to 600V. It features high temperature resistance, aging resistance, acid and alkali resistance, moisture resistance, water resistance, oil resistance, corrosion resistance, flame retardant and other properties.
• SATA Power Wires
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.
Rhein Z1 uses OFC copper wire as SATA power wires: The copper wire crystal is evenly distributed by the high temperature hot casting mode continuous casting method, and the current conduction is good and introduce less electrical noise while power loading varies during system is accessing SSD.
• Server Grade SATA Cable
The server grade SATA cable is optimized to ensure the stability of the signal transmission by having the irregular distribution of the SATA cable in the foam layer is easy to generate a telecommunications irregular magnetic field, which affects the signal transmission quality. Also it uses durable SATA connectors at both end to ensure the best quality of connectivity.
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 Block Diagram
VitOS: An operating system specially built for music server.
1. Dual Firmware: Prevent from being damaged while firmware upgrade.
2. Network accelator: Accelerated network processing
3. USB Audio Optimizer: Optimized USB Audio processing

VitOS Music Server
Average Latency: VitOS average latency is the same as ROCK， and lower then Mac mini for 23.72%
Max. Latency: VitOS max. latency is lower then ROCK for 5.21 %，and lower then Mac mini for 8.65 %
Standard deviation of latency: VitOS is lower then ROCK for 7.69 %, and lower then Mac mini for 11.11 %
Variation of latency: VitOS is lower then ROCK for 14.29 %， and lower then Mac mini for 25 %
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.

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).
