New & Standout Features The H150 introduced several "firsts" and upgrades compared to the outgoing H120: Built-in MM Phono Stage: For the first time at this level, Hegel included a high-quality Moving Magnet phono preamp derived from their standalone V10 phono stage. USB-A Drive Support: You can now plug a solid-state drive or hard drive directly into the back for local file playback, controlled via the app. Advanced Streaming: It supports Spotify Connect, Tidal Connect, Qobuz Connect, Apple AirPlay, Google Cast, and UPnP. It is also "Roon Ready" (though certification may still be pending depending on your current firmware). TV Integration: One of the optical inputs is specifically optimized for TV use, and the amp comes pre-loaded with IR codes for most major TV remotes, allowing you to control the amp’s volume with your Samsung, LG, or Sony remote. Key Specifications & Performance Power Output: 75 Watts per channel into 8 Ohms (Class AB). Damping Factor: Over 2000. This is exceptionally high for an amp in this class, providing "grip" and authority over speaker woofers for tight, controlled bass. SoundEngine 2: Features Hegel’s patented feed-forward technology that cancels out distortion in real-time. DAC: A custom 4-layer design inspired by the high-end Viking CD player, utilizing an AKM-based architecture for natural, neutral sound.
