Silent Angel Bremen SL1 Plus | High-Resolution Wireless Music Streamer & DAC

The Silent Angel Bremen SL1 Plus (SL1P) is an all-in-one high-resolution network music streamer with a built-in DAC, balanced XLR outputs and wireless streaming capabilities. Designed for modern HiFi systems, it combines Roon Ready playback, Spotify Lossless, Qobuz, TIDAL and AirPlay 2 with flexible analog and digital connectivity.

Powered by Silent Angel's VitOS operating system and a six-core processor, the Bremen SL1 Plus provides a dedicated streaming solution for integrated amplifiers, preamplifiers, powered speakers and external DACs. Its full-width chassis, isolated DAC circuitry and expandable SSD storage make it equally suited to an existing stereo system or a new digital music setup.

High-Resolution Streaming with Roon Ready

The Bremen SL1 Plus supports a wide range of music streaming platforms and playback options, allowing listeners to access online services and personal music libraries through a single component.

Its streaming capabilities include:

• Roon Ready: Integrates with an existing Roon system for music library management and multiroom playback.

• Spotify Connect with Lossless: Supports lossless streaming through Spotify Connect with updated firmware.

• Qobuz and TIDAL: Access high-resolution music streaming services.

• AirPlay 2 and DLNA: Stream from compatible Apple devices, computers and network music libraries.

• Internet Radio: Explore radio stations from around the world.

• VitOS Orbiter: Control playback, browse music and manage the streamer from a mobile device.

Silent Angel's March 2026 firmware update added Roon Ready certification and Spotify Lossless support, expanding the SL1 Plus's streaming capabilities.

Dedicated DAC with Balanced XLR and RCA Outputs

The Bremen SL1 Plus incorporates a dedicated digital-to-analog converter housed in its own aluminum enclosure. By physically separating the DAC from the main digital processing and power circuitry, Silent Angel aims to reduce electromagnetic interference and preserve analog signal integrity.

Balanced XLR and unbalanced RCA outputs allow the SL1 Plus to connect directly to compatible integrated amplifiers, preamplifiers and powered speakers.

For listeners who already own an external DAC, the SL1 Plus also provides coaxial, optical and USB digital audio outputs, allowing it to function as a dedicated network streaming transport.

Wired and Wireless Network Connectivity

With both Gigabit Ethernet and Wi-Fi, the Bremen SL1 Plus accommodates a variety of listening environments. Its wireless connectivity simplifies installation where a wired network connection is unavailable, while Ethernet provides a dedicated wired connection for high-resolution streaming.

The SL1 Plus can also be paired with Silent Angel's Bonn series of audiophile network switches for systems requiring specialized network infrastructure.

Expandable Music Storage

In addition to streaming services, the Bremen SL1 Plus supports locally stored digital music libraries.

An internal M.2 NVMe SSD expansion slot accommodates up to 4TB of optional storage, while two USB 3.0 ports and one USB 2.0 port provide additional connectivity for external music drives.

This flexibility allows listeners to maintain a personal collection of high-resolution music alongside their preferred streaming services.

Audiophile Engineering and Power Design

The SL1 Plus combines a six-core processing platform with Silent Angel's audio-optimized VitOS operating system. Its internal construction incorporates a dedicated DAC enclosure, EMI shielding and a thick copper layer on the main circuit board and SSD section to assist with heat dissipation.

A custom switching power supply, described by Silent Angel as radar-grade, is engineered for stable, low-noise operation. The galvanized steel chassis, aluminum front panel and polished aluminum bottom cover provide a substantial foundation for the internal electronics.
