...previously

We built live prototypes and took measurements from them in order to confirm theories in practice and improve sound quality.

And the theories were confirmed!

  • Frequency response (1/3 octave smoothing)
    Frequency response (1/3 octave smoothing)

    The drop in frequency response above 30 kHz and the nonlinearity below 200 Hz is due to limitations of the measurement microphone and measurement conditions. The real nonlinearity is ± 0. 5 dB in the range 100 –35, 000 Hz, and + 0. 5 / − 3 dB in the range 45 – 70, 000 Hz.

  • Minimum phase response (1/3 octave smoothing)
    Minimum phase response (1/3 octave smoothing)

    In the most critical area, the deviation of the phase response from the minimum phase is not more than ± 10 °, providing the most natural effect of the presence of live performers.

    Presented are graphs of test prototypes that can be improved in production samples.

  • Step response

    The step response ensures that recordings are played back at the highest possible resolution.

  • Impulse response

    The impulse response ensures that recordings are played back at the highest possible resolution.

But that’s just math & engineering.

Our story

Precision Fidelity was founded in San Francisco, CA around 1973. Around because, unfortunately, precise information on the company’s early years is not available. The historical record really began in 1977, when Precision Fidelity was acquired by The Hill Group, a holding based in San Diego. That year marked a real milestone: Gabriel Sakakeeny joined the company as Chief Designer and Vice-President of Operations. He created products that Precision Fidelity built its reputation on in the years that followed: the C - 7 preamplifier, the M - 7 power amplifier, and the JB - 1 phono stage.

In 1979, The Hill Group sold the company to Bruce Moore, Mark Kassab and Jack Senecal. This deal marked the beginning of Precision Fidelity’s decline. Senecal became lead designer, after which Gabriel left for National Controls. His decision was influenced by a striking shift in Precision Fidelity’s approach to both design and sound.

Although the company was defunct by the end of the 1980s, to this day, audio enthusiasts and professionals not only recognize the PF acronym, but highly esteem the equipment itself. Indeed, Precision Fidelity created excellent audio devices that differed markedly from the mainstream offerings flooding the market at the time.

Today, we are reviving the Precision Fidelity brand. Though none of us was part of the original company, and though we take pride in creating unique devices from scratch, we continue to support PF’s underlying philosophy. We devote a lot of time and effort to giving the world more than decent sound at a good price; we strive to bring exceptional devices to the market at a fantastic price. We sincerely believe that audio equipment should be high quality, reliable and affordable, all at once.

The new age of Precision Fidelity has just begun. The company’s rebirth is not merely a marketing affair. It is the outgrowth of our sincere desire to make high quality audio equipment that satisfies all of our customers, whether they’re esoteric audiophiles or professional sound engineers.
