Every sound-critical point in the PRE G2 is fitted exclusively with the finest components procurable worldwide, and in part custom-made for Audionet. For example, the selected filter capacitors, as well as the bulk of our high audiograde electrolyte capacitors with a dielectric, are made of silk. We place on mica capacitors, insert selected high voltage foil capacitors, and deploy high-quality silver-gold alloys for our internal wiring.

The double mono set-up guarantees a complete channel separation. The implementation of SMD miniature technology optimizes high frequency properties, whereas the magnetically and capacitively optimized chassis and circuit prevent interference. Controlling and signal processing units are optically decoupled to ensure no feedback on the source signal. To not employ electromechanical elements underlines the effort, to leave the music signal as untouched as possible. Volume adjustment is achieved by electronically switched precision resistors. The chassis is insensitive against microphonic effects.

For each channel there is an encapsulated 100 VA toroid core transformer, two special audio capacitors with 41,000 uF and fast, discrete regulators to ensure stable supply voltages. Additionally the voltages are smoothed locally by 12 discrete regulators for each channel. There is an extra power supply for the control unit.

All operational amplifiers in the signal path are discrete and optimized. The 10 operational amplifier modules have a gain-bandwidth product of 1.5 GHz. The input operational amplifiers have a nearly infinite input impedance and a constant capacity. Therefore, they do not overload the signal source.

The signal and ground of the inputs are switched via gold-coated precision relays. The output operational amplifiers are class A amplifiers with high bias current and are insensitive against reflux of the power amplifiers.
