SMSL PH-1
High Fidelity MM Phono Amplifier
SMSL PH-1 is a high-fidelity MM-only phono amplifier designed to deliver rich, full, and dynamic vinyl sound in an ultra-compact form. With precision tuning and advanced circuitry, it brings out the best in your MM cartridge setup.
Golden Gain, Super Energy
While most entry-level MM phono amps offer only 38–40dB gain, PH-1 delivers a fixed 46dB gain. This results in approximately 1Vrms output—perfect for modern amplifiers, with fuller dynamics and denser sound, all without overloading the next stage.
Exclusive MM Design, Ultra-Low Distortion
PH-1 is exclusively designed for MM cartridges, unlike many models with MM/MC switching. This dedicated design removes unnecessary MC circuitry, improving circuit performance by 50%, enhancing user convenience, and keeping costs low while maintaining top-tier sound quality.
CNC Compact Machining
The high-precision CNC-machined chassis ensures mechanical stability and excellent EMI resistance. Whether in complex electromagnetic environments or daily use, PH-1 delivers stable, pure performance.
Reliable "Quantification" for Vinyl Playback
For vinyl enthusiasts, PH-1 also serves as a reliable reference tool. It helps identify playback issues and pairs well with step-up transformers, allowing the use of MC cartridges through external SUTs with weak amplification but great sound.
Palm-Sized but Fully Featured
Measuring just 94×30×96mm, PH-1 offers six full-size connectors (power, L/R input, L/R output, GND) while maintaining a spacious layout. Its compact form factor allows for easy placement without compromising usability.
Integrated Headphone Amplifier
PH-1 features a built-in high-quality headphone amp with a front-panel 6.35mm jack. Ideal for scenarios where speakers are inconvenient, it can also act as a preamp volume controller for active speakers.
Advanced Isolated Power Supply
With a dual isolated power supply design and external DC input, PH-1 eliminates common AC hum and ground noise issues. It ensures a dark background and clean sound, while allowing users to upgrade the power supply for even better performance.
Built with Relentless Precision
PH-1's development took over 2 years, involving more than 5 PCB revisions, 50 op-amp candidates, and extensive cartridge and component testing. Every detail was optimized to offer accessible high-end sound, even for beginners.
Plug and Play Simplicity
Designed for ease of use, PH-1 is plug and play—no complex settings. Gain is fixed at 46dB, capacitance at 150pF, with only headphone volume adjustable. Connect your gear and instantly enjoy the warmth of vinyl.
