Silent Angel Rhein Z1 Plus 250GB High-Performance Music Server

The Silent Angel Rhein Z1 Plus 250GB is a high-performance audiophile music server engineered for high-resolution streaming, local music storage and advanced digital audio playback. Combining an Intel quad-core processor, high-speed NVMe solid-state storage, precision clock technology and a fanless aluminum chassis, the Z1 Plus provides a dedicated digital source for reference two-channel audio systems.

Designed to operate as a Roon Server, Roon Bridge, DLNA server or USB audio transport, the Rhein Z1 Plus offers flexibility for a wide range of digital playback configurations. Its USB audio output supports PCM up to 32-bit/768kHz and DSD512, while its processing capabilities enable Roon DSP transcoding from PCM to DSD256.

Two independent Gigabit Ethernet ports allow the Z1 Plus to connect to a network while providing a separate connection for a compatible network audio player. Each Ethernet port has its own precision TCXO clock, and a dedicated 25MHz external master clock input provides an additional upgrade path.

Internally, Silent Angel combines carefully selected components with electromagnetic interference filtering, dedicated power regulation and a graphene-assisted cooling system. The result is a purpose-built music server designed to accommodate demanding high-resolution libraries and sophisticated streaming systems.

Designed for High-Resolution Music Streaming

The Rhein Z1 Plus provides a dedicated computing platform for digital audio, eliminating the need to use a general-purpose computer as the primary music server.

Its Intel J6413 quad-core processor works alongside 16GB or 32GB of DDR4 memory and NVMe SSD storage to support demanding playback applications. Users can store a local music library, stream music over the network or connect the Z1 Plus directly to a compatible USB DAC.

Silent Angel's VitOS operating system supports several playback configurations, including Roon Server, Roon Bridge, DLNA and HQPlayer Network Audio Adapter. VitOS Manager provides access to network configuration, software installation, firmware updates, music importing and library backups.

The Z1 Plus can also serve multiple compatible audio players simultaneously, making it suitable for both dedicated listening rooms and larger networked audio installations.

Precision Clocking and Electrical Noise Management

Silent Angel equips the Rhein Z1 Plus with two independent 25MHz temperature-compensated crystal oscillators, one for each Gigabit Ethernet port. This design separates the clocking of the two network interfaces.

For systems incorporating an external master clock, a dedicated 25MHz input allows the internal clock source to be bypassed using the appropriate clock selection control.

The Z1 Plus also incorporates high-frequency filtering at its power input and USB audio output, along with electromagnetic interference absorption around internal components. Its NVMe SSD features dedicated power regulation and additional EMI treatment.

A fanless cooling system combines graphene material, a copper heatsink and the aluminum chassis to dissipate heat without introducing mechanical fan noise. These measures are intended to reduce electrical and mechanical interference within the server.

Technical Specifications

A Flexible Digital Source for Reference Audio Systems

The Rhein Z1 Plus can be configured to suit several digital audio architectures. Connect it directly to a compatible USB DAC for high-resolution playback, use it as a Roon Server to manage a music library, or deploy it as a dedicated network audio transport.

Its dual Ethernet architecture also makes it suitable for systems incorporating audiophile network switches and other specialized networking equipment.

For users seeking additional clocking options, the 25MHz external master clock input provides a path for integrating compatible precision clock components.
