DESCRIPTION

“The Audionet PRE1 G3 preamp is a high bandwidth designed around its own state of the art microprocessor – controller. In order to optimize its stellar high-frequency attributes, circuit size has been reduced to the absolute minimum. Moreover, the remaining signal paths are kept to a minimum, and are as free of sound-critical components as possible. Audionet boasts only carefully selected high-quality components, like the fast discrete voltage regulators with low-noise gallium arsenide precision voltage references, high audio-grade electrolyte capacitors with a silk dielectric and selected high-current film capacitors with the lowest possible loss angle. Inside we find silver/gold internal cabling.” 

“Audionet uses gold-coated precision-relays to switch the input signal and earth. All wiring is star grounded at one central point. Its input buffer is a cascaded, bootstrapped, monolithic double- FET, offering virtually infinite input impedance. A DC-coupled driver stage amplifies the signal distortion free for the subsequent circuitry. Cleverly, the volume and balance are set by an electronically switched, real time linearized high precision resistor network. The output driver combines high-speed bipolar op-amps with discrete A/B-drivers with high bias current and the voltage for the input and output stage are additionally smoothed by two discrete ultra-fast bipolar regulators. An encapsulated 50 VA toroid core transformer and high audio grade electrolyte capacitors with a capacity of 30,000 uf provide the supply voltage. The PRE 1 G3 utilizes a microprocessor to control and regulate the whole function. The digital section has its own power supply while the digital control is both physically and electrically isolated.”

The Pre 1 is a flexible unit that can be fine-tuned. Inputs can be named and their sensitivity adjusted.

It has an exceptionally clean and clear sound packed with detail, impressive authority and bass power and great stereo imaging.

Remarks: a) This unit comes with Audionet RC1 remote handset that costs €300 extra. b) It can be upgraded with an external power supply: Either AudioNET EPX or EPS. c) Fair overall condition and appearance with some visible cosmetic wear including some marks and light scratches on the top and front panels. We can send you pictures of the aesthetic issues.
