Cadence Phono Preamplifier

The Cadence is unique among all phono preamplifiers offered in the market. A specially designed phono step-up transformer, the heart of the unit, provides the ideal interface between a moving coil phono cartridge and carefully engineered low noise circuitry. The performance parameters offered by this complement of electronic components far exceeds any other phono preamplifier/equalizer offering to date.
