At AXPONA 2025, PS Audio unveiled its highly anticipated PMG Signature Series, marking a significant advancement in ultra high-end audio performance. The lineup includes the PMG Signature 512 DAC, 512 Preamplifier, Signature Phono Preamplifier, and SACD Transport, each meticulously engineered with redesigned chassis and overhauled internal architectures. Priced uniformly at $8,499 per component, the series sets a new benchmark for audiophile excellence.
The PMG Signature 512 Preamplifier features a fully balanced design from input to output, achieving an ultra-low noise and distortion floor of 150dB. A newly developed power supply replaces traditional electrolytic capacitors with high-quality film capacitors, enhancing transient response and dynamic range. The double-chassis construction provides superior shielding against noise and interference, while the innovative gain stage combines FET and BJT technologies operating in pure Class A. This stage employs a folded cascode topology, allowing high voltage swings and wide bandwidth without the instability typical of conventional designs.
Complementing the preamplifier, the PMG Signature 512 DAC is equipped with the PureStream DSD512 engine, capable of converting any digital audio format into an 8X-DSD stream without relying on PCM or decimation. The SpectraWave 64-tap sequencer processes the signal to reduce noise and distortion while ensuring precise time alignment. The DAC's direct-coupled analog output stage, integrated high-end streamer, and Digital Lens technology work in tandem to deliver seamless music access and exceptional sound quality.
The Signature Phono Preamplifier is designed with a transimpedance input and a zero-feedback topology, minimizing distortion, coloration, and noise. It supports both moving coil and moving magnet cartridges, offering remote-controlled loading and gain options to adapt to various systems. Utilizing discrete FETs and BJTs in Class A mode, the preamp achieves exceptional headroom, ultra-low noise, and wide dynamics, capturing the full nuances and spatial depth of vinyl recordings.
Lastly, the PMG Signature SACD Transport features galvanically isolated outputs and an ultra-low jitter design, enhancing both CD playback and SACD detail extraction when connected via I²S. This transport effectively unlocks the raw DSD layer of SACDs, providing an unprecedented level of detail and separation. The galvanic isolation ensures that noise and ground contamination are eliminated, resulting in enhanced image separation and transparent reproduction.
The PMG Signature Series is available in black or silver through PS Audio's official distribution channels and authorized dealers. With its combination of advanced technologies, precise engineering, and meticulous attention to detail, the series represents a significant investment for audiophiles seeking the pinnacle of sound reproduction.
