Hegel D50 DAC

Overview

The Hegel D50 DAC is a dedicated digital-to-analog converter that takes the digital signal from a streamer, CD transport, TV, computer or network player and turns it into clean, detailed analog sound for your amplifier or preamplifier. Hegel nicknames it the Raven, and it draws on more than two decades of the company's DAC design work. It's for listeners who already have a good amplifier and want their digital sources to sound as natural and open as their best records.

The D50 handles PCM up to 32-bit/384 kHz and DSD256 over USB, and up to 24/192 with DSD64 on its AES/EBU and coaxial inputs, with MQA decoding across all of them. Incoming signals are reclocked by three dedicated master clocks, one for S/PDIF and separate clocks for the 48k and 44.1k sample-rate families over USB, so the DAC chip receives a precisely timed signal.

Much of the work goes into keeping noise out. Two low-noise toroidal transformers split the power supply, one for the noisier digital and standby circuits and one for the sensitive analog and digital sections, each shielded in thick steel and filtered. The DAC chip sits on its own raised board for short signal paths, and an aluminium housing with a milled aluminium front plate and aluminium feet keeps the design solid and understated.

Simcoe Audio Video Insight

The D50 is a fixed-output DAC, so it's built to feed an integrated amplifier or preamplifier with its own volume control rather than drive power amplifiers directly. Use the balanced XLR output if your amplifier has one, especially on longer runs. Its input sensing can wake the D50 and switch to a source as soon as it detects a digital signal, and you can set whether it switches inputs or simply powers on. Automatic standby and display dimming keep it out of the way once it's set up.

Why the Hegel D50 Stands Out

Three Master Clocks

Precise timing for S/PDIF and USB.

Dual Toroidal Transformers

Separate, shielded digital and analog supplies.

Raised DAC Board

Short signal paths, less interference.

Up to 32/384 and DSD256

Over USB, with MQA decoding.

Six Digital Inputs

AES/EBU, BNC, RCA coaxial, 2 optical, USB.

XLR and RCA Outputs

True balanced and single-ended.

Buyer's Guide

Who It's For

  • The Separates Builder: Wants a dedicated DAC for an existing amplifier.
  • The Multi-Source Listener: Has a streamer, transport, TV and computer to connect.
  • The Detail-Focused Listener: Wants low noise and precise timing from digital files.

How It Compares

The D50 is a standalone converter, so it suits a system built from separates. Pair it with an amplifier or preamplifier you're already happy with and you add AES/EBU, BNC coaxial and three dedicated master clocks without replacing anything else in the chain.

Hegel D50 DAC FAQs

What digital inputs does the Hegel D50 have?

One AES/EBU, one coaxial BNC, one coaxial RCA, two optical and one USB input.

Which formats does the Hegel D50 support?

USB handles up to 32-bit/384 kHz and DSD256 (DoP). AES/EBU and coaxial handle up to 24/192 and DSD64 (DoP), and optical up to 24/96. All inputs support MQA 8x.

Does the Hegel D50 have a volume control?

No. Its XLR and RCA outputs are fixed at 2.5 V, so connect it to an amplifier or preamplifier with its own volume control.

Can the D50 turn on automatically?

Yes. Input sensing can wake it when a digital signal is detected, and you can choose whether it also switches to that input.
