Product Highlights

Specifications: Output Wattage: 70 Watts per channel into 8 ohms (110 Watts per channel into 4 ohms). The David Berning ZH270 is an innovative output transformerless (OTL) power amplifier utilizing patented radio-frequency impedance conversion to drive dynamic loudspeakers directly. By eliminating audio output transformers, it delivers ultra-fast transient response and transparent signal purity. Equipped with two line-level inputs, an A/B input selector, a built-in volume attenuator, and a 3-position feedback switch, the ZH270 functions seamlessly as a standalone power amplifier or a minimalist integrated unit with automated tube biasing.

Reviews acclaim the ZH270 for uniting solid-state speed and bass authority with pure tube musicality. Critics highlight its expansive soundstage, grain-free clarity, and articulate transient resolution across complex passages. Reviewers particularly praise the variable feedback feature for easy speaker matching, as well as its silent background and effortless retrieval of micro-dynamic details.

Adding this acclaimed design to your setup provides a transparent window into your music collection with zero maintenance hassles thanks to its automated biasing and protective circuitry. Its unique capability to drive sources directly while delivering lightning-fast, lifelike dynamics makes it an extraordinary investment for any music enthusiast seeking pristine sound quality.
