Description
PS Audio PMG Signature Pre Amplifier
The PS Audio PMG Signature Pre Amplifier is a groundbreaking achievement in high-end audio, offering unparalleled acoustic transparency and ultra-low distortion. Designed to reveal every nuance of your music, it delivers explosive dynamics, infinite depth, and holographic imaging that immerses the listener.
With a vanishingly low noise floor of -145dB, this preamplifier uncovers every detail that traditional designs cannot. As the first PS Audio product in fifty years to carry the name of founder Paul McGowan, the PMG Signature Pre Amplifier is a personal statement of excellence.
It provides an uncoloured, direct connection between your music and your emotions, making it more than a component. It is a conduit to the purest musical experience possible.
Innovative Design and Engineering
The PMG Signature Pre Amplifier represents a bold leap in design and engineering, combining fully balanced circuitry with revolutionary power supply and amplification technology. Its dynamic range approaches 150dB, capturing the quietest and loudest moments in music with extraordinary precision.
Lightning-fast, zero-feedback Diamond buffers preserve every musical nuance while a film-capacitor-based power supply provides immense dynamic swing and grace. The bandwidth extends beyond 500kHz, offering exceptional openness and realism.
Every stage of the preamplifier is engineered to maintain absolute sonic fidelity, and high-speed circuits eliminate distortion and preserve transient integrity. This is a design focused not on refinement alone but on completely redefining the possibilities of preamplifier performance in high-end systems.
Application and Performance
Serving as the central hub of any high-performance audio system, the PMG Signature Pre Amplifier ensures every source is delivered with absolute fidelity. It handles DACs, phono stages, CD players, and other digital or analogue inputs with total precision.
The preamplifier converts all incoming signals to fully balanced, passing them through zero-feedback Class A Diamond buffers, ensuring nothing is added or removed. With five identical balanced and single-ended inputs, it maintains full isolation between sources and amplification.
The preamplifier provides ultra-low distortion, complete control, and seamless integration into complex audio systems. It defines the final gateway through which music flows, guaranteeing that every note, every subtle harmonic, and every nuance is faithfully reproduced for the listener.
Technology and Features
The PMG Signature Pre Amplifier incorporates state-of-the-art technology designed for the most demanding audiophiles. It features a fully balanced Class A output stage, stepped attenuator with 1/10th dB precision, and a film-capacitor-based power supply for high-current performance.
Zero-feedback Diamond buffers provide transparency, speed, and complete control over the musical signal. The analogue signal path is free of capacitors, ensuring the purest audio reproduction. Inputs include four balanced XLR and two single-ended RCA pairs, while outputs feature two balanced XLR and two single-ended RCA pairs.
Its fully complementary differential design achieves some of the lowest distortion and noise levels in the world, ensuring an unmatched listening experience with infinite dynamic range and lifelike resolution.
