Leema Acoustics has been busy developing their Sirius streaming music server system with help from digital audio boffins, Innuos.

The great news is that Sirius is now available worldwide.

Sirius is a hi-fi grade streaming music server system that provides a high-performance solution for the storage and playback of digital music. In partnership with Innuos, Leema’s ex-BBC engineers have combined audiophile performance with the convenience of a UPNP/DNLA-compatible music server.

Sirius brings together audiophile components with a powerful server-grade main circuit board. This is all handled by a high-speed quad-core processor with up to 8 gigabytes of system memory. You have a choice of storage size of 2, 4, 6 or 8TB.

CD transfer utilises a high-performance TEAC optical drive and makes digitising large music libraries simple. Sirius offers backup for CD audio, right up to lossless FLAC files and supports WAV, AIFF, ALAC, OGG Vorbis, AAC and MP3. Additionally, there is a USB 3.0 connection for audio backups.

A key feature of the Sirius is its high-quality asynchronous USB DAC employing an ESS ES9038PRO SABRE DAC from the company’s flagship range. Also of note is the Xmos USB interface. The DAC supports 16, 24 and 32 bit-depths, from 44.1kHz up to 384kHz with DSD 64, 128 and 256 also supported.

If you already happen to be kitted out with a high-end DAC, the Sirius’ ultra-low-noise USB output offers Class 1, Class 2 and DoP external connections. Balanced outputs via XLR and unbalanced RCAs are also offered.

I am further impressed by the dual-Ethernet connection on the Sirius. This enables you to use one for your router and the other for a dedicated streamer connection.

The device is compatible with a wide range of playback systems including: Sono multi-room; Naim Mu-so/Uniti; Denon HEOS; Squeezebox; Linn DS; Pioneer N-50A; Cambridge Audio CXN and Denon 720AE.

Further features include editable metadata and album art, support for Tidal, Spotify, BBC iPlayer and internet radio, plus simple importation from computers, USB and NAS drives. There’s also a three-way linear power with a dedicated supply for the DAC.

The Sirius is available now from £3,995 (for 2TB).
