Product: Quad Twenty Four P

Product description

The Quad Twenty Four P is a state-of-the-art preamplifier designed with the analog purist in mind. This preamp features a moving magnet/moving coil switch and direct/variable volume control, making it compatible with all types of amplification. A striking feature of the Twenty Four P is that, unlike Quad’s power amplifiers, these preamps use a completely new design. With transformers designed by one of the world’s leading authorities and relay input circuitry, the musical signal is preserved in its purest form. This reflects the philosophy of the ‘theoretically perfect amplifier’, as defined by Peter Walker: ‘a straight wire with amplification’.

Cosmetic description

The device is in excellent cosmetic condition “new condition”. The design reflects the classic Quad aesthetic, an addition to any interior.
