JMF Audio PHS 7.3 Phono Amplifier

The PHS 7.2 and PHS 7.3 are dual-mono and symmetrical phono preamplifiers, featuring JMF Audio's unique precision balanced input stage design and innovative ALP and ALP-EM linearization technologies. These phono preamplifiers can handle up to 2 (PHS 7.2) or 3 (PHS 7.3) tone-arms or record players. Their advanced hand-calibrated balanced input stage and high gain take full advantage of low-level moving coil cartridges, without the need for step-up transformers.

The innovative input module interfaces provide 16 resistive and 16 capacitive loads for each input and corresponding cartridge, for precise dampening and tuning of the upper range of frequencies to achieve a linear overall response. The load settings are assigned to each input which allows seamless switching from one tone-arm to another. The record collector oriented PHS 7.3 features a special mono mode and three optimized alternative compensation curves for the enjoyment of pre-RIAA era recordings.
