Shanling EH90 Desktop R2R DAC/AMP

The EH90's fully discrete headphone amplifier uses an advanced MOSFET design matched to the R2R DAC section to balance transparency, power and natural sound. With up to 5.2W @ 32Ω from the balanced output, it can drive demanding full-size headphones with ease.

A dual-power supply separates the digital and analogue sections for lower noise. The EH90 uses a custom 35W linear transformer, a dedicated 10W digital power supply and filtering capacitors totalling over 12,000μF for clean, stable power delivery throughout.

Digital inputs include USB, optical, coaxial, I2S, HDMI ARC and AES/EBU. Headphone outputs cover 6.35mm single-ended plus 4.4mm and XLR balanced. RCA and XLR analogue outputs let the EH90 serve as a preamp or line-level source for powered speakers or a wider hi-fi system.

HDMI ARC allows direct connection to compatible TVs and AV setups. Bluetooth 5.4 supports wireless playback from phones and tablets with LDAC, aptX Lossless, aptX Adaptive, aptX HD, aptX, AAC and SBC codecs.

The FPGA-assisted I2S input offers selectable pinouts for wider transport compatibility. External clock input at 44.1kHz and 10MHz is also supported for use with a dedicated master clock.

The EH90 features a rigid aluminium chassis, clean front-panel controls and a 4.8-inch colour display for playback information and settings access.

Flagship R2R Sound

Using 212 precision 0.01% resistors in its 24-bit DAC module, the EH90 delivers the organic, natural sound that R2R conversion is known for.

Fully Discrete Headphone Amplifier

Shanling developed a new fully discrete amplifier stage specifically for the EH90, using advanced MOSFET architecture paired with the R2R DAC section. The design provides strong current output and stable performance across a wide range of headphones.

Powerful Balanced Output

With up to 5.2W @ 32Ω from the balanced output, the EH90 handles both sensitive and demanding full-size headphones with confidence.

Flexible Hi-Fi Connectivity

RCA and XLR preamp outputs allow the EH90 to connect directly to active speakers, power amplifiers or other hi-fi components alongside its headphone outputs.

Modern Digital Integration

USB, optical, coaxial, I2S, HDMI ARC and AES/EBU inputs give the EH90 wide compatibility with digital sources. HDMI ARC suits living room systems, while Bluetooth 5.4 adds quick wireless playback from phones and tablets.
