THÖRESS EHT Integrated Amplifier MKIII
Best high fidelity amplifier for discerning audiophiles seeking exceptional sound.
The THÖRESS EHT Integrated Amplifier MKIII is a revolutionary component that redefines the relationship between vacuum tubes and solid-state technology. Operating in pure Single-Ended Class-A mode, this amplifier utilizes vacuum tubes for voltage gain and a unity-gain MOSFET stage for current buffering. The result is a 20-watt-per-channel amplifier that drives difficult speaker loads with authority while retaining the holographic soundstage, texture, and flow of a purist tube amp. The MKIII introduces a redesigned driver stage built around NOS Philips SQ E81L tubes, offering exceptional linearity and long-term reliability. It features zero global feedback, a high damping factor, remote volume control, and selectable bass boost presets.
