The Thesis φ (phi) is a no-compromise phono preamplifier for all vinyl connoisseurs using a top-class turntable. Just like the α or λ preamps, it is also fed by the Thesis π twin PSU. By using two independent – MM (moving magnet) and MC (moving coil) – amplifier circuits, it is possible to use two record players connected simultaneously. Cartridge matching is highly customisable for gain and impedance on the rear panel of the unit by jumpers. Noise characteristics, dynamic range, headroom and frequency response of the Thesis φ are second to none.esse and “live” magic usually achieved only by 300B triodes in valve amplification.
