Shanling SM1.3R In-House R2R DAC Hi-Fi Network Streamer

Exceptional R2R DAC Performance

The SM1.3R features the second generation of Shanling's in-house developed R2R DAC, a true high-end solution previously released with the SCD3.3 SACD player. Its upgraded R2R assembly utilizes 212 0.01% ultra-precise resistors for the 24-bit DAC module, employing a 19-bit architecture with a 4-bit compensating code and an assistive push-pull differential circuit. This delivers smooth, natural R2R sound with true high-fidelity precision and clarity, eliminating the digital roughness typical of Delta-Sigma DACs.

Split Power Supply for Peak Sound Quality

The SM1.3R adopts a split power supply design that separates power delivery between the streamer and audio sections. This eliminates harmful interference between the two halves of the device. A pair of custom-made 31W toroidal transformers offers extremely low noise and high efficiency, with an additional potting process to reduce unwanted vibrations. This linear power supply is especially critical for the analog section, providing cleaner and more stable power than switching alternatives.

Optimized High-End Sound Performance

Adapting advanced ACCUSILICON clocks (45.1584MHz and 49.152MHz), the SM1.3R delivers enhanced accuracy and performance when decoding high-resolution music. Supported by Shanling's AGLO system for bit-perfect playback on Android, the device handles Hi-Res audio up to 32-bit / 768kHz and DSD512. Two dedicated circuits—MUSES8920 for clean line-out and TPA6120 for headphone amplification—ensure versatile, high-quality analog output.

Modern Streaming Platform

Running on a closed Android platform with a 64-bit ARM Cortex CPU, 4GB RAM, and 64GB internal memory, the SM1.3R provides stable and balanced performance. It supports direct access to streaming apps including Spotify, TIDAL, Qobuz, Apple Music, Amazon Music,Apple Classical,Presto Music, and KKBox. Full support for TIDAL Connect, Qobuz Connect, and ROON Ready allows easy streaming from phones and tablets, along with DLNA and AirPlay 2.

Seamless Connectivity and Signal Stability

Equipped with gigabit LAN and dual-band Wi-Fi 6 (2.4G/5G), the SM1.3R ensureshigh-speed, stable internet connections for uninterrupted streaming. A Qualcomm QCC5125 Bluetooth module supports LDAC, apt HD, apt Adaptive, apt LL, aptX, AAC, and SBC. The device also includes an FPGA-assisted I2S output with broad compatibility, serving as a versatile I²S transport.

Refined & Robust Design

Following the standard set by Shanling's SACD and CD players, the SM1.3R adopts a minimalist, robust aluminum construction with a glass top, rounded edges, and a 5.8-inch 1080p Sharp touch screen. The Eddict Controller app (Android & iOS) enables full-screen mirroring and remote control, providing seamless operation across local file playback and streaming apps.
