Silent Angel Unveils Munich M1 Streamer and M1T Media Transport

The Silent Angel audio brand, owned by the Chinese company Thunder Data, presented two devices under the general German name Munich, with the M1 and M1T indices: a Network Music Streamer and Media Transport. In fact, these are specialized multimedia computers, the electronics of which are optimized to minimize noise, interference and other specific digital problems that interfere with clear audio reproduction.


ARM Cortex-A72 processor

Both are powered by a quad-core ARM Cortex-A72 processor running at 1.5GHz coupled with a 32GB DRAM (low noise DDR4) ROM. All circuitry, according to the developer, is thought out specifically for lossless processing of musical data.

For this purpose, an optimized computer sound processing circuit was created. Its fanless cooling also corresponds to complete noise reduction: a special radiator is installed in the system, which lowers the operating temperature by 20°C. A certain “EMI absorber” contributes to the reduction of electromagnetic interference, the details of which the brand does not disclose.


Built-in DAC

Unlike the Munich M1T media transport, the Munich M1 streamer is equipped with a built-in DAC with a headphone amplifier. Thus, M1 is able to directly output a signal, including to active speakers. Otherwise, both new devices are twins, and well equipped.

Possible interfaces include AES/EBU, I2S, coaxial digital output, USB Audio output, and a Gigabit Ethernet port. Both devices are promised to work well with NAS and applications for high-speed network streaming.


VitOS own operating system

One of the important features can be considered its own audio operating system VitOS, with which both devices, according to the manufacturer, allow you to easily control playback. Both models support audio resolutions up to PCM 768kHz and DSD 11.2 MHz (DSD256) depending on the selected output.

Silent Angel Munich M1T

Devices accept AAC, M4A, MP3, OGG, FLAC, WAV, ALAC, DSD (DSF, DFF), WAV64, AIFF, CUE, WMA, APE files and are capable of transmitting signals to a DAC that supports MQA decoding. The descriptions of both devices are accompanied by the Tidal, Qobuz, Roon Ready, Apple Airplay and Hi-Res Audio logos. Management of all device functions is available from the smartphone screen through a proprietary application.


Availability and price

In the UK both devices are already available for order. The Silent Angel Munich M1 costs £1,000 and the M1T £700.
