Shanling EH90 Black Hi-Fi DAC & ADC Interface

Desktop R2R DAC and Balanced Headphone Amplifier for Serious Listening

The Shanling EH90 Black is a high-end desktop audio component that combines a discrete R2R digital-to-analog converter, a fully balanced headphone amplifier, a preamp stage and a line-level source in one chassis. Designed for listeners who want the organic character of resistor-ladder conversion without sacrificing modern system flexibility, this unit sits at the centre of a headphone rig or a full Hi-Fi setup. Its panoramic 4.8-inch colour display, rigid aluminium chassis and clean front-panel controls reflect Shanling's 90-series design language.

What Sets the EH90 Apart in the Desktop DAC Category

At the core sits Shanling's Pro R2R DAC module, built around a precision array of 212 ultra-accurate 0.01% resistors in a 19-bit architecture with a 4-bit compensating code and push-pull differential circuit. The fully discrete MOSFET headphone amplifier stage was developed specifically to match the DAC section, delivering strong current output across a wide range of headphones. A dual-power supply design — a custom 35 W linear transformer plus a dedicated 10 W digital supply — keeps more than 12,000 µF of filtering capacitance between the two domains for low-noise operation.

Technical Parameters That Matter for Desktop Audio

The numbers translate directly into real-world listening flexibility, from serious headphone power to wide format support across every common digital source a modern listener might own.

• Balanced Headphone Output: 5.2 W + 5.2 W @ 32 Ω (high gain) — drives power-hungry planar and dynamic headphones with authority
• Single-Ended Output: 1.32 W + 1.32 W @ 32 Ω (high gain) via 6.35 mm jack for conventional headphone connections
• Format Support: PCM up to 32-bit / 768 kHz, DSD512 over USB and I2S; PCM up to 192 kHz / 32-bit via optical, coaxial, AES/EBU and HDMI ARC
• Bluetooth: 5.4 with LDAC, aptX Lossless, aptX Adaptive, aptX HD, aptX, AAC, SBC for high-quality wireless playback from phones and tablets

Who the Shanling EH90 Is Built For

The Shanling EH90 is the right choice for desktop audiophiles who want a single component to anchor a headphone rig, a powered-speaker setup or a TV-based living-room system. Headphone listeners with demanding full-size models benefit from the 5.2 W balanced output and 0.6 Ω output impedance, which keeps damping factor high across sensitive and hard-to-drive cans. System builders can use the RCA and XLR preamp outputs at 2.5 V and 5 V respectively, while HDMI ARC integration makes the unit a natural fit for modern living-room setups. The included remote and 4.8-inch front-panel display keep everyday operation straightforward from the listening seat.
