Home Audio System Core

To set up a great audio system, the audio source is crucial.


An exceptional audio steward is hereby to present the music originally as the artists intended.


CNC Processing Chassis

Fan-less technique makes no mechanical noise.

Made of ingeniously aerospace Industrial grade aluminum alloy.

Expert Thermal Solution 

Quality upper case as the CPU heat-sink.

Lower CPU operating temperature results in 15% lower thermal noise.


Specially Built Motherboard

- Dedicated circuit solely for audio usage.

Llow noise for high quality music playback with shortest data path, to have the smoother and purer data transmission.


Ultra Low Power Consumption 

- CPU consumes power consumption (as 6W) to reduce electrical noise from CPU, and make the network signals inside stable.

High Permeability EMI Absorber

Adopting specially chosen EMI absorber at the inner side of bottom case to eliminate high frequency electrical noise from internal digital circuit including DRAM, CPU, etc.

Connection Ports

USB Audio port for USB DAC, USB 2.0 and USB 3.0 ports for external storage, HDMI for engineer test only.


Audio Grade SSD Technology 

- The new internal storage board provides pure SSD power, greatly reducing the transmission distance of SATA signals, only 2CM.

Noise Reduction

Supporting dual SSD, while using low power consumption M.2 SATA SSD, lower the electrical noise on power rail.

Customized Application

250 GB specialized SSD for system disk.

1 TB / 2 TB specialized SSD for data disk, up to 2 simultaneous zones for multi-room streaming applications.


Audio operating system designed for music servers that focuses on streaming services.

VitOS improves machine efficiency, performance stability and network latency.

Product Parameters


Data Disk:  

Black, Silver; (requires other colors can be customized)

Z1 Standard version has 250GB system sisk for system usage only. You can choose Z1 NAS version, which has an additional 1TB or 2TB SSD Data Disk.

Power Inlet: 


12V DC @ 3A max. (Spec. 5.5mm x 2.5mm, tip carries +12V)

USB Audio X 1; USB 3.0 X 1; USB 2.0 x 2; Gigabit Network X1
HDMI X 1 (service interface); power connector X 1



DSD Support:

200x200x65 (mm)

3.75 KG ( Net Weight )

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 Z1 only support DSD music up to DSD64 (which means DSD128 or DSD256 is not supported in DoP mode).

Number of music:

Z1 is designed to handle 100,000 songs or 4TB music files smoothly.

DSP Ability:

All DSP functions available in the PCM domain including upsampling. And the transcode ability is to transcode from DSD256 to 384Khz PCM.

Important notice:

Because of MinimServer 0.8 license change (see MinimServer web site: https://minimserver.com), newly installation MinimServer on Z1 will not be able to work. Existing installation of MinimServer can continue to use with some limitation.
