Rhein Z1

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 

Audio Grade SSD Technology V2

The new internal storage board design provides pure SSD power, greatly reducing the transmission distance of SATA signals only 2CM (previous version is
18cm), supporting dual SSD, while using Low power consumption M.2 SATA SSD: Lower the electrical noise on power rail inside Z1, added EMI absorber to reduce M.2 SATA SSD EMI noise

Brand new CPU thermal solution

Use the aluminum alloy upper case as the CPU heatsink. Lower CPU temperature while operating: 10 Degree C lower than previous version ,Lower internal temperature results in 15% lower thermal noise inside the Rhein Z1 than previous version (in 25 degree C room temperature)

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.

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.

OpenSSL 1.1.1b  26 Feb 2019

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 topology:

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.
