Hegel H600 Reference Integrated Amplifier and Streamer at Vinyl Sound Buffalo, NY USA

The Hegel H600 is the reference integrated amplifier from Hegel Music Systems (Oslo, Norway), available at Vinyl Sound in Buffalo, NY, USA. Engineered as the highest-expression single-box amplifier Hegel has ever produced, the H600 delivers 303 watts per channel into 8 ohms in a dual-mono Class AB configuration, with a damping factor exceeding 4,000 and stable operation down to 2-ohm loads. The onboard DAC is an ESS Sabre ES9038Q2M-based bit-perfect converter supporting USB at 32-bit/384 kHz and DSD256 via DoP, shielded from internal interference by a dedicated thick-steel enclosure and its own power supply. The preamplifier section borrows the ultra-precise volume attenuator from Hegel's reference P30A, and the entire amplification chain is governed by Hegel's patented SoundEngine2 feed-forward distortion correction. Streaming is handled by a comprehensive platform supporting Spotify Connect (Lossless), Roon Ready, Tidal Connect, AirPlay, Google Cast, airable Internet Radio, UPnP, and JPLAY. The H600 earned the EISA High-End Streaming Amplifier 2023-2024 award, a SoundStage! Reviewers' Choice, a SoundStage! Recommended Reference Component designation (2023), and The Absolute Sound Solid State Integrated Amplifier of the Year 2025.

Reference Amplification: SoundEngine2 and Dual-Mono Architecture

The H600's amplifier section is a true dual-mono design, with each channel maintaining its own independent circuitry from the power supply rail through the output stage, minimizing inter-channel crosstalk to below -100 dB. Governing each channel is Hegel's patented SoundEngine2, a feed-forward error correction system that monitors the amplified signal in real time and cancels distortions as they arise, rather than applying conventional negative feedback after the fact. Because SoundEngine2 operates predictively without looping the corrected signal back through the gain chain, it avoids the phase-related trade-offs of high-order feedback topologies, delivering measured THD below 0.005% at 50 W into 8 ohms with exceptional transient response and an absence of artificial hardness. The preamplifier section incorporates the same ultra-low-noise precision volume attenuator found in the standalone P30A reference preamplifier, ensuring the extremely low-amplitude source signal is handled with the same care found in a dedicated reference two-box system.

Reference-Grade DAC and Comprehensive Streaming

The H600's digital section is built around the ESS Sabre ES9038Q2M chip in a bit-perfect configuration that performs no resampling or upsampling, preserving the native resolution of every source format. The converter accepts USB input at up to 32 bits and 384 kHz and DSD256 via DoP, with coaxial BNC and RCA inputs supporting 24/192 and DSD64 via DoP, three optical inputs handling 24/96, and a network LAN port for 24/192 and DSD64 streaming. A thick steel shield and a dedicated power supply isolate the DAC board from electromagnetic interference generated by the amplifier stage, ensuring a noise floor and dynamic range commensurate with the amplifier's own performance. The streaming engine supports Spotify Connect (Lossless), Roon Ready, Tidal Connect, AirPlay, Google Cast, airable Internet Radio and Podcast, UPnP, and JPLAY Certified, with all digital inputs except USB equipped with signal sense for automatic source switching and amplifier wake-up. Firmware updates are delivered automatically and at no cost, keeping the H600 current as streaming platforms evolve.

Frequently Asked Questions

What is the Hegel H600?

The Hegel H600 is Hegel's reference integrated amplifier and streamer, built in Oslo, Norway. It delivers 303 watts per channel into 8 ohms in a dual-mono Class AB design, incorporates a bit-perfect ESS Sabre DAC supporting USB at 32/384 kHz and DSD256, and provides a full suite of streaming services including Roon Ready, Tidal Connect, Spotify Connect, AirPlay, and Google Cast. The H600 represents Hegel's most advanced single-box audio solution.

How does the Hegel H600 compare to the Gryphon Diablo 300?

The Gryphon Diablo 300 is a Class A/B Danish integrated amplifier rated at 300 W into 8 ohms, widely praised for its rich tonal density, built-in DAC option, and optional phono stage. The H600 matches it closely in rated power (303 W vs. 300 W) while offering a substantially higher specified damping factor (more than 4,000 vs. approximately 400 for the Diablo 300) and a far more comprehensive streaming platform with Roon, Tidal Connect, Google Cast, and AirPlay built in as standard. The Gryphon delivers more Class A operational character and optional phonostage flexibility, while the H600 excels as a complete digital hub for a modern streaming-first high-end system.

How does the Hegel H600 compare to the Naim Supernait 3?

The Naim Supernait 3 is a well-regarded British integrated amplifier rated at 80 W into 8 ohms, designed around Naim's DR (Discrete Regulation) power supply and featuring a built-in MM phonostage. The H600 offers substantially more power (303 W vs. 80 W), a much higher damping factor, and far more extensive built-in streaming and DAC capability, whereas the Supernait 3 is aimed at buyers who prioritize Naim's characteristic rhythmic drive and analogue source compatibility in a more compact form factor. The H600 is better suited to larger rooms and more difficult loudspeaker loads.

What is SoundEngine2 and how does it differ from SoundEngine?

SoundEngine2 is the second generation of Hegel's patented feed-forward distortion correction circuit. Like the original SoundEngine found in the H30A and P30A, it predicts and cancels distortions as they are introduced into the signal path, without looping a corrected signal back through the gain stage as conventional negative feedback does. SoundEngine2 extends the operating bandwidth and effectiveness of the error correction circuit relative to the original, and it also enables efficient Class AB operation at lower bias levels, which reduces heat generation and allows the H600 to maintain its full rated power without thermal throttling. The result is lower distortion, faster transient response, and greater power efficiency compared to the first-generation circuit.

Does the Hegel H600 have a phono stage?

No, the H600 does not include a built-in phono preamplifier. Hegel's engineers opted to omit the phonostage in order to maximize the performance of the amplification, DAC, and streaming sections, recognizing that a phonostage of commensurate quality would require significant additional circuitry and shielding. Vinyl enthusiasts pairing the H600 with a turntable will need an outboard phono preamplifier connected to one of the two RCA line-level inputs or two balanced XLR inputs.

What streaming platforms does the Hegel H600 support?

The H600 supports Spotify Connect (Lossless), Roon Ready, Tidal Connect, AirPlay, Google Cast, airable Internet Radio and Podcast, UPnP, and JPLAY Certified. All digital inputs except USB incorporate signal sense for automatic source detection. Firmware updates are delivered automatically at no charge, ensuring the streaming platform remains current as services evolve. The H600 also supports multi-room synchronization via Roon, AirPlay, and Google Cast.
