Nu Prime AMG STA

HOLISTIC AUDIOPHILE SOLUTIONS

The AMG STA offers remarkable amplification at a very competitive price point. This powerful yet compact performer can integrate seamlessly with almost any quality preamplifier, and really shines when used with its stable mate the AMG PRA preamplifier.

The AMG STA comprises of several state-of-the-art innovations in power amp design. Its class-leading features include 1M Ohm input impedance, high instantaneous current for power delivery, 700kHz switching frequency, and Single-Ended Non-Negative Class A module coupled with Double Feedback Class D module for 300W mono amp power.

The AMG series front panel embodies its spirit. It is milled from a 15mm harden aerospace aluminum 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.

AMG STA PCB integrates ground wire shielding to isolate external interference. The 300 Mhz bandwidth JFET provides ultra-high input impedance and wide-band fast response. The dynamics of the design and the single-ended Class A circuit enriches the natural second harmonic.

This design allows the most delicate details in the audio signal to carry through the chain. The level of transparency in sound reproduction is genuinely astonishing in this class of equipment, with a deft in creating a highly detailed sonic imagery.

The AMG-STA uses the “Single-Ended, Non-Negative Feedback” Class-A module partners with a new “Double feedback” Class D circuitry. The Class D oscillating frequency has increased to 700kHz, which is 1.4 times that of the STA-9.
