Key Highlights
Simplified design focuses on core performance by removing tone controls and A/B input switching.
Integrated mu-metal-shielded power transformer eliminates the need for an external power adapter.
Retains HM1's Class A output stage and negative feedback disengagement for personalized sonic tuning.
Introducing the Zähl H1, a stripped-down yet highly refined iteration of its acclaimed sibling, the HM1. Built on the same advanced core technologies, the H1 maintains the hallmark precision, transparency, and robust power reserves that have garnered accolades for its predecessor. However, this model offers a simplified feature set targeted at users seeking uncompromising sonic performance without auxiliary functionalities deemed unnecessary for the majority of applications.
A notable adjustment in the H1 is the removal of tone controls and switchable A/B inputs—features that, while powerful, are often underutilized by audiophiles focused purely on playback fidelity. This streamlining has allowed Zähl to integrate a power transformer directly into the chassis, protected by shielding crafted from mu-metal to minimize interference. With this integrated design, an external power adapter is no longer required, offering both convenience and an elegant aesthetic.
