Audiophile MM/MC Phonostage with Discreet Componentry
Phono Box S2 Ultra uses a fully discrete, Op-Amp-free design that fosters sonics rarely found in this class. On top of omitting Op-Amps, the selected polystyrene capacitors (known among audiophiles as the ‘holy grail’ for phono preamplifiers) significantly contribute to the clean, clear, detail-oriented sonics that S2 Ultra delivers. With wide-ranging flexibility in gain, load & capacitance, it can handle with grace almost any cartridge you throw at it. Split RIAA equalization creates an ultra-accurate representation of the RIAA curve, further refining what you hear. To protect the circuitry from potentially harmful interference, the S2 enclosure features a 2-layer enclosure comprised of aluminum & steel.
