As simple as possible but no simpler.

The job of a phono-preamp for a turntable cartridge is to amplify by 1,800 times the typically 0.003V signal from a moving coil cartridge to drive a pre-amplifier while being absolutely transparent to the music retrieved from the groove. At the same time reverse the RIAA pre-emphasis that was used when cutting the LP without adding a sonic signature. To achieve this, the Genesis Phono Pre-Amplifer was designed to be “as simple as possible but no simpler” with a minimum number of components, but each component had to be the very best available. As manufacturing tolerances do not allow some of the components to reach the precision needed, they are meticulously hand-selected. The very best extremely transparent opamp was selected and the RIAA de-emphasis circuit was put outside the main signal path to minimize its sonic signature.

The Design

The Genesis Phono-Preamp is designed from the base of the tone arm onwards, and a Genesis designed cable is supplied with a mini-DIN connector – the standard with most high-end tone arms. There isn’t a plethora of loadimg options. The inductance of the coil of the cartridge interacts with the capacitance of the tonearm cable to create a reactive peak. This peak can be as high as 32dB, and is the usual reason given for all the loading options for a phono stage. However, when the graphs of this reactive peak are shown in the marketing literature of many phono stages, the frequency scale is often omitted. In computer simulations, we can easily see that this reactive peak is in the megahertz range – far outside our hearing. However, if this peak is present, it can easily cause problems for a phono-preamp. High loading (if used to tame this peak) also reduces dynamics and transparency.

Each Genesis Phono-Preamp is individually hand-crafted using the finest hand-selected precision tolerance parts. A highly engineered internal damping platform significantly reduces all kinds of mechanical vibration leading to more extended natural bass, and detail and resolution.

Platinum Phono

Phono Pre-Amp Editions

  • Gold – using optimally hand-selected components;
  • Platinum – the very best hand-selected components, an outboard power supply, tone-arm cable plus a HMWA acoustic suspension for further vibration control;
  • Diamond – dual-mono using the very best hand-selected components with acoustic suspension and dual external power supplies for the very best isolation.

Acoustic Suspension System

The Genesis Platinum and Diamond edition of the Phono Pre-Amp comes with an acoustic suspension system that isolates the amplifier from floor or structure borne vibrations. Designed like the suspension system of a race car, the acoustic suspension is made of an acrylic suspension frame, neoprene shock absorbers tuned to the weight of the Phono Pre-Amp module, and steel spikes to anchor the suspension frame to rack or ground.
