The Magma New HPS from NAT stands as a towering achievement in audio engineering, crowned as the brand’s flagship power amplifier. Operating in pure Class A, single-ended triode configuration with zero global feedback, this amplifier redefines high-fidelity sound. The HPS designation signifies a significant leap forward from the standard Magma, delivering unmatched performance and versatility. Named for the glowing, magma-like hue of its anode, the Magma New HPS is a visual and sonic marvel, representing the most powerful single-ended amplifier with a single tube ever crafted.
Unparalleled Power and Flexibility
The Magma New HPS offers two distinct operating modes: a high-power setting delivering up to 170W and a moderate setting of up to 60W, both utilizing a pure direct-heated triode (DHT) design. This flexibility allows the amplifier to drive nearly any speaker with ease, making it a versatile powerhouse for audiophiles. At its core lies the GM100, the highest-power vacuum tube designed for audio, capable of dissipating up to 1,000W of heat. NAT optimizes its operating point to reduce working temperature, enhancing reliability while maintaining exceptional audio quality. The robust mechanical construction of the output tube, paired with a specially designed, high-mass, non-magnetic cover cage, minimizes environmental vibrations, resulting in superior micro-detail and clarity in sound reproduction.
For listeners with sensitive speakers, the moderate 60W mode reduces heat dissipation and power consumption, ensuring efficient performance without compromising quality. This thoughtful design makes the Magma New HPS adaptable to a wide range of audio setups.
High Damping Factor for Superior Control
One of the standout features of the Magma New HPS is its high damping factor mode, achieved by connecting the speaker cable to the 4-ohm output tap. This configuration enhances control over the speaker, reducing total harmonic distortion (THD) and improving frequency response behavior. The result is a tighter, more precise sound with exceptional clarity and dynamics, even at high power levels. The pure symmetric output transformer ensures seamless operation in this mode, setting a new standard for single-ended amplifiers.
Premium Components for Uncompromising Sound
The Magma New HPS employs a meticulously selected double triode 6N6P tube for its input and driver circuit, chosen from the highest-quality new old stock (N.O.S.) for its neutral and natural sound reproduction. The custom-designed, wide-bandwidth output transformer by NAT delivers an impressive frequency range of 9Hz to 70,000Hz, maintaining remarkable flatness for a high-power single-ended amplifier. This ensures that every nuance of the audio signal is preserved, from deep, resonant bass to sparkling highs.
High-mass, laboratory-grade connectors accommodate 4-ohm and 8-ohm speaker loads, ensuring secure and reliable connections. Every component in the Magma New HPS is engineered for precision, contributing to its status as a reference-grade amplifier.
A Sonic and Visual Statement
The Magma New HPS is more than just an amplifier it’s a statement of NAT’s commitment to pushing the boundaries of audio excellence. Its ability to deliver powerful, transparent, and dynamic sound makes it a cornerstone for any high-end audio system. Whether driving demanding speakers in high-power mode or delivering refined performance in moderate mode, the Magma New HPS offers an unparalleled listening experience that captivates audiophiles and music lovers alike.
