THÖRESS EHT Mono Power Amplifier

The EHT topology combines the harmonic richness and musicality of vacuum tubes with the power, control, and efficiency of a Class-A MOSFET output stage. This allows the amplifier to drive demanding loudspeakers with authority while maintaining the natural, fluid sound signature associated with high-end tube gear.

The amplifier features a six-position gain selector ranging from 4dB to 25dB. This allows you to precisely match the amplifier's sensitivity to your preamplifier and loudspeaker efficiency, ensuring an optimal signal-to-noise ratio and ideal volume control range.

THÖRESS prioritizes signal purity by omitting sound-degrading protection circuits. While this design choice ensures the highest possible audio fidelity, it requires the user to be mindful of proper startup and shutdown procedures to protect sensitive loudspeaker components.

The amplifier includes subtle, integrated bass boost options designed to help compensate for room acoustics or to provide a fuller sound profile with smaller monitor speakers. These adjustments are implemented to enhance low-end presence without compromising the overall transparency of the midrange.

With an output of 50 watts into 4 ohms, this amplifier is capable of driving a wide variety of loudspeakers. However, its performance is best suited for systems where the amplifier's refined Class-A character can shine, rather than systems requiring massive power reserves for extremely inefficient, low-impedance loads.

Point-to-point wiring eliminates the need for printed circuit boards, which can introduce parasitic capacitance and signal interference. This traditional, labor-intensive construction method ensures a shorter, cleaner signal path and makes the unit significantly easier to service or maintain over its long lifespan.
