Silent Angel Munich M1, Silent Angel Munich M1T und Silent Angel Bremen B1

Thunder Data Co. Ltd. describes the solutions of the Silent Angel brand as innovative solutions developed with the aim of ensuring the sound of the best analogue hi-fi components when streaming high-resolution content.

Silent Angel Munich M1, Silent Angel Munich M1T and Silent Angel Bremen B1 are three solutions that have been developed with the aim of providing the highest level of sound enjoyment. Silent Angel is a brand of Thunder Data Co. Ltd, a very young company that sees itself as a music integrator and hi-fi solution provider and was founded in 2017.

Thunder Data Co. Ltd. is specifically dedicated to modern networked consumer electronics components, whereby one can certainly speak of a technology-driven company, but which, according to the promise, always focuses on the best sound quality and thus wants to create solutions that can meet even the highest demands of hi-fi enthusiasts.

Silent Angel Bonn Series as an introduction

The company’s first product, the Silent Angel Bonn Audio grade Network Switch, caused quite a stir. This is a solution specially designed for the requirements of streaming audio and video content, which found its continuation in the Silent Angel Bonn N16 LPS Audio grade Network Switch, two devices which together represent the Silent Angel Bonn Series.

The Silent Angel Rhein Series, specifically the Silent Angel Rhein Z1 High-performance Music Server, is another central component of the network for music streaming, and the Silent Angel Munich Series and Silent Angel Bremen Series offer music streamers and music transport solutions.

Silent Angel Munich Series and Silent Angel Bremen Series

The solutions of the Silent Angel Munich Series and Silent Angel Bremen Series are dedicated to the end devices in a networked hi-fi world, whereby, according to the company, very special approaches are pursued.

The ambitious development team around company founder Dr. Eric Jian Huang, who spent part of his studies in the Rhineland and probably found the inspiration for the name here, has set itself the goal of clearly surpassing the sound quality of audio CDs.

In the meticulous search for the genuine musicality and emotionality usually associated with high-quality analogue technology, the company came to the realisation that conventional computers are only suitable to a limited extent for the provision of audiophile content, as too many processes run simultaneously and can thus impair the transmission of sensitive audio data.

In addition, commercially available computers have inadequate shielding against interference signals. For Thunder Data Co. Ltd. it became clear that modern music streaming environments require completely new technological approaches. The result is an independent product range of streamers, music servers and accessories that exemplify the company’s motto: Silent Angel components are designed to help people live more enjoyable lives through great technology.

Silent Angel Munich M1 and Silent Angel Munich M1T

According to the manufacturer, both the Silent Angel Munich M1 music server and the Silent Angel Munich M1T streaming transport are consistently designed for audiophile music transmission.

The Silent Angel Munich M1 and Silent Angel Music M1T systems are based on the specially developed VitOS and feature, first and foremost, powerful ARM Cortex-A72 processors with four processor cores and a clock speed of 1.5 GHz, which, together with 32 gigabytes of flash ROM memory, exclusively take care of audio processing. The housing layout, which has been specially optimised for hi-fi applications, ensures an operating temperature of only 20 °C with its specially developed heat sink and does not require any annoying fans.

In addition, a highly efficient EMI absorber filters out electronic interference and ensures accurate transmission of high-resolution audio data. The manufacturer promises that this guarantees an emotional sound fascination that makes the listener forget all digital technologies.

For both systems, the manufacturer speaks of extensive interface equipment, which helps to ensure that the Silent Angel Munich M1 music streamer and the Silent Angel Munich M1T streaming transport can be seamlessly integrated into sophisticated hi-fi chains of all sizes.

The digital outputs in AES/EBU, I2S and S/PDIF format support sample rates of up to 384 kHz as well as DSD128, while the USB interface can even transfer files of 768 kHz PCM as well as DSD256. Another USB port is available for external storage media, while the Gigabit Ethernet port ensures a reliable connection to high-performance NAS drives as well as routers and audio switches. In addition, the two streamers with M-IO and M-LINK connections are optimally equipped for future expansion possibilities, as the company states in the description of these solutions.

While Silent Angel Munich M1T is specially designed for use with high-quality external D/A converters, the Silent Angel Munich M1 also has a powerful headphone amplifier as well as high-quality analogue outputs and can also be operated with analogue amplifiers or active speakers.

Both systems can be conveniently controlled via app, the VitOS Orbiter app for Apple iOS and Google Android, they allow direct access to Amazon Music, TIDAL, Qobuz, HIGHRESAUDIO and Spotify, rely as dlna-certified streaming solutions on the UPnP standard and also understand Apple AirPlay and are designated as Roon Ready.

Silent Angel Bremen B1 Network Music Streamer

The second streaming product line of the Silent Angel brand, the Silent Angel Bremen Series, currently has only one product available, namely the Silent Angel Bremen B1 Network Music Streamer.

The focus here is on the VitOS developed by Thunder Data Co. Ltd., which forms the basis for a particularly compact yet versatile streaming client.

The Silent Angel Bremen B1 Network Music Streamer makes the outstanding sound quality of Silent Angel available to music lovers who also value wireless convenience, according to the manufacturer’s description.

It connects to all kinds of playback devices via WiFi or Bluetooth, and the VitOS Light app for Apple iOS and Google Android makes controlling it child’s play. The device can also be connected to routers or NAS drives via the integrated Ethernet port.

As a dlna-certified streaming client, access to resources in the network is possible via UPnP, the system is equipped for Spotify via Spotify Connect and for TIDAL via TIDAL Connect, allows access to Qobuz, Napster, Deezer, Amazon Music and TuneIn.

The Silent Angel Bremen B1 Network Music Streamer also features a powerful 1.2GHz ARM Cortex-A7 audio processor, a powerful fanless power supply and EMI absorbers that effectively prevent high-frequency interference from affecting valuable audio data. The Silent Angel Bremen B1 Network Music Streamer is equipped with both analogue RCA outputs and digital interfaces in AES/EBU, I2S and S/PDIF format, seamlessly connecting to analogue playing partners and external D/A converters.

Optimisation through matching accessories

Thunder Data Co Ltd maintains that any audiophile component can only be as good as its power supply, and that’s where the Silent Angel Forester F1 linear power supply comes in, designed to bring Silent Angel streamers to sonic peak.

Symmetrically arranged high-performance toroidal transformers, voltage stabilisation with MOSFET transistors and efficient EMI shielding ensure an accurate and stable power supply without any impurities and thus provide a fascinatingly uncluttered sound image that allows hours of music enjoyment without any signs of fatigue.

But that’s not all, according to the manufacturer, the supply cables can also be optimised. For this purpose, the DC cables of the Silent Angel Bastei Series are offered.

These are supposed to come up trumps with gold-coated plugs, an effective shielding made of high-purity copper, Teflon insulators as well as a noble cotton sheathing. With Light Orange and Snowy White, two different cable types are available, which differ in the conductor material used and show subtle differences in sound. In this way, every hi-fi lover can find the right high-end cable for their personal taste and individual requirements, according to Thunder Data Co. Ltd.
