Stage Two Phono Amplifer
Sugden A21SE Stage Two Moving Magnet & Moving Coil Phono Amplifier
The Stage Two offers true high-end phono amplification in a compact, heavy weight, minimalist two box design. Separating the amplification from the power supply helps reduce interference and increase resistance to pick-up noise.
The single input accepts both Moving Magnet and Moving Coil cartridges. Input selection is internal together with adjustments for 47K, 100 and 470 ohm impedance settings. The input of the Stage Two is a low noise, low distortion instrumentation amplifier. Current feedback circuitry achieves wide bandwidth and an excellent dynamic response.
The circuit has been combined with a dual FET-input, low distortion operational amplifier with superb dynamic response and low noise. The amplifier is mains operated.
