The Artemis Labs PH-1 is a tube-based phono preamplifier designed specifically for medium- to high-output phono cartridges, either moving coil or moving magnet. It features a three-stage design with passive RIAA equalization, achieving a flat frequency response within ±0.2 dB from 20 Hz to 20 kHz and ±0.5 dB up to 40 kHz, which is important for high-resolution playback. The unit uses high-quality tubes: one 6N1P, two 12AX7/ECC83, and two 5687 tubes, with a Cool-Swap™ configuration that provides idle spares and cooler running tubes. The output stage uses a single 5687 triode with choke loading for low distortion and high linearity, capable of driving loads as low as 8k ohms without cathode followers. The PH-1 employs low-gain MOSFET high voltage regulation per channel to minimize cross-talk and maintain stable sound. It includes a TexTool™ ZIF socket for phono inputs allowing easy attachment of shunt loading resistors or capacitors without soldering. The chassis and internal wiring use military-style terminal boards and point-to-point wiring to minimize sonic degradation. The unit weighs 24 lbs and measures 6.5" H x 8.5" W x 14.6" D. It inverts absolute polarity and has an output impedance of approximately 1300 ohms at 1 kHz. The PH-1 is handmade in the USA using premium parts and is praised for its tonal balance, detail, smoothness, and presence, making it a strong choice for audiophiles seeking a tube phono stage with excellent sonic performance and build quality.
