Heed Thesis Phi
Heed Thesis Phi is a hand-built high-performance audiophile phono pre-amplifier, which can be used in conjunction with the Heed Thesis Pi upgrade PSU, a it’s a compact high-end component at a realistic price, superior build and performance in a top-quality package.
The Thesis φ (phi) is a no-compromise phono pre-amplifier for all vinyl connoisseurs using a top-class turntable. Just like the α or λ pre-amps, 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

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.
– totally separated MM and MC stage (simultaneous work)
– adjustable MC gain and impedance
– discrete bipolar transistor architecture
– exceptional noise floor
