Shanling EH90 Desktop R2R DAC/AMP - Silver

The EH90 combines a fully discrete headphone amplifier with 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 will drive demanding full-size headphones with ease.

A dual-power supply design separates the digital and hi-fi sections for improved isolation and 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.

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 power amplifiers.

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

The FPGA-assisted I2S input offers selectable pinouts for wider transport compatibility. The EH90 also accepts an external clock input at 44.1kHz and 10MHz for use with a dedicated master clock.

The EH90 uses 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 R2R conversion is known for. If you are also interested in a streaming solution using R2R technology, Shanling offers the SM1.3R HiFi Music Streamer with R2R DAC.

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 its balanced output, the EH90 is built for serious headphone listening. It offers the power and control needed for both sensitive and demanding full-size headphones.

Flexible Hi-Fi Connectivity

Alongside its headphone outputs, the EH90 includes RCA and XLR preamp/line outputs for connection to active speakers, power amplifiers or other hi-fi components.

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 provides quick wireless playback from phones and tablets.
