Nu Prime AMG PRA : Preamplifier

The NuPrime AMG PRA went beyond being a transparent preamplifier with 1M Ohm input impedance and the best analogue source inputs. A user-selectable 4 stage “Active Low Frequency and Harmonic Gain” control gave it distinctive characteristics to enhance the speaker performance, a world-first in preamplifier design.

Details:

The AMG series front panel embodies its spirit. It is milled from a 15mm harden aerospace aluminium alloy using a four-axis CNC machine with a diamond cutter through a 48 steps process. Design elements such as the 3D “floating” logo, the curved surface around the front panel switch, and diamond-cut edge bring the quality of ultra-high-end audio products to the affordable range of the AMG series.

The design goal for AMG PRA was to deliver a transparent sounding analogue preamplifier with its distinctive characteristics. Several new design concepts were developed and used in the AMG-PRE besides 1MΩ input impedance to achieve the best analogue inputs.

Users of smallish speakers would often detect a distinct drop in bass response with some audio tracks. Instead of a simple “Bass Boost” function that lifts a targeted low-frequency band, a user-selectable 4 stage “Active Low Frequency and Harmonic Gain” control compensates for the lack of bass presence. It achieves some bass extension and a more natural roll-off.

Additional features such as the 2 stage gain control and invertible phase control increase the compatibility of the AMG-PRA with other power amplifiers.

Technical Details:

The layout of the AMG-PRA takes excellent care in isolating the sensitive audio signals from the power circuitry. The power circuitry comprising of a star topology power and ground layers is built on one board while a separate board houses the pre-amplification circuit. An isolation layer separates these two boards, which further minimizes interference.

The effect is a highly transparent sound that is natural and not over etched.

MUSES72320 Digital Volume Control

ONE MEGA ultra-wide bandwidth low noise JFET, single-ended Class A input design and MUSES8920 Op-amp produce harmonics similar to vacuum tube amps, which has a “warm, airy and velvety” sound characteristic.

Non-feedback low-frequency domain Frequency Harmonic Modulation circuit provides minimum phase distortion and tone error.

Inputs and outputs are fully balanced design.
