Aurorasound Preda line stage preamplifier
£8000
Preda is a solid state preamplifier with analog IN/OUT employing state-of-the-art transformer-type volume control system.
The transformer uses super-reliable lead relays with 54-step, permitting precise setting with perfect Infrared remote control. Unlike conventional resister-type attenuator, the transformer system has no loss of signals, as heat, enabling precision volume control settings.
Aurorasound’s newly developed discrete amp-module, having achieved ultra wideband and low distortion, balances input signal sources and adopt any type of output power amplifiers with excellent signal control.
Preda is developed with a completely new concept by adopting independent block for power supply, amplifiers, input and output modules for each L/R channels. A heavy duty solid aluminum chassis, extruded knobs, anti-vibration foot insulators are employed to achieve the highest-level musical performance, operation and aesthetics.
Gain select switch is added on the bottom of chassis. This function is more minus 16 step down foe mid-night listening.
