SMSL PH-1 MM Phono Amplifier
The SMSL PH-1 is purpose-built to deliver pristine analog audio for MM (moving magnet) cartridges. Unlike dual MM/MC models, PH-1 is optimized solely for MM use, ensuring superior circuit design, performance, and ease of use. With a fixed gain of 46dB and a capacitive input set at 150pF, it’s engineered to meet the demands of modern turntable setups while avoiding the compromise of switchable circuits.
Measuring just 96mm x 94mm x 30mm and weighing only 230g, the PH-1 is palm-sized yet full-featured. Its chassis is CNC-machined for durability and EMI resistance. The unit includes gold-plated RCA inputs/outputs, a 6.35mm headphone jack, and a headphone volume knob for standalone listening. A robust isolated DC power supply ensures minimal HUM noise and interference, delivering a clean, transparent background.
Performance specs back its design philosophy: THD+N is -81dB, channel separation -77dB, dynamic range 85dB, and frequency response spans 20Hz–20kHz. Whether you’re a beginner seeking simplicity or an audiophile refining a vintage setup, the PH-1 provides an accurate, dynamic sound stage without clutter or complexity.
