LUMIN launches S2 network player with external DAC inputs

LUMIN has introduced a network player that also converts audio from external digital sources. The LUMIN S2 uses two ESS SABRE ES9038PRO DAC chips in a dual-mono configuration and is available for €9,990.

The S2 draws on the X1’s architecture while using a newer LUMIN processing platform. Its fully balanced dual-mono analogue output stage couples the output connectors through two Lundahl LL7401 transformers. Two femto clocks work with FPGA clock distribution. An internal dual-toroid power supply provides separate analogue and digital rails with dual-stage regulation, integrating the power supply and player into a single chassis.

External sources such as CD transports can connect through one coaxial RCA S/PDIF input and one optical TOSLINK input. Both accept PCM from 44.1 to 192 kHz at 16–24-bit, or DSD64 through DoP. Analogue connections comprise balanced XLR outputs rated at 6 Vrms and unbalanced RCA outputs rated at 3 Vrms. The USB digital output supports native DSD512 or stereo PCM from 44.1 to 384 kHz at 16–32-bit.

Network playback supports up to DSD512 or stereo PCM at 384 kHz/32-bit, with upsampling available to DSD256 or 384 kHz PCM. The S2 provides full MQA decoding and MQA QRONO d2a filters for PCM playback except through AirPlay. Leedh Processing handles digital volume control.

Gigabit RJ45 Ethernet and a Gigabit SFP network connection can operate simultaneously. Streaming support includes TIDAL Connect, Qobuz Connect, Spotify Connect, Amazon Music, KKBOX, QQMusic and internet radio. The S2 is Roon Ready and supports UPnP/OpenHome, AirPlay, JPLAY and Audirvāna integration, with control available through the LUMIN app for iOS and Android. Its shared USB port also accepts single-partition storage formatted as FAT32, exFAT or NTFS.
