The PRE30 employs a Class A coupled, discrete fully balanced circuit topology utilized for the best possible signal-to-noise ratio and audio fidelity. J-FET devices, coupled in a fold back cascade, feature prominently in the input stage providing lighting fast transient response with ample high-frequency "air" and "openness". DC servos are avoided in all critical low-level amplifier stages in favor of thermally compensated current loading and MOS-FET devices ensures ultra wide-bandwidth audio performance.

A massive, custom-made Toroidal transformer using double regulators is employed in the PRE30's massive power supply. Combined with a sophisticated multi-stage regulator network that makes sure all amplifier stages receive highly regulated current for the best possible dynamic range and headroom. Even the best sounding "shunt to ground" type volume control is used further illustrating the uncompromising attention to engineering detail so evident throughout the PRE30.

Designed for exceptional ease-of-use and set-up, the PRE30 features several unique features. Each of the seven inputs (two balanced, five single-ended) is individually assignable and adjustable for sensitivity (gain). A throughput input allows the PRE30 to be used in conjunction with a surround sound processor in a combined use home theater / stereo music system. For convenience, a remote link performs the on/off function of a connected Primare power amplifier.
