NuPrime AMG HPA
- The input stage uses a JFET with ultra-high bandwidth and low noise for the 1MΩ input impedance. The amplification circuit employs a Single-Ended, Non-Negative Feedback Class A module for a wide frequency bandwidth and pristine second-order harmonics.
- Fully balanced amplification consisting of independent circuits for input, volume, gain, and power output stages. The volume control uses two MUSES72320 to achieve a fully balanced volume adjustment with 100 levels (0-99). This is the best volume control Nuprime has mounted in a product and likely the best for any headphone amplifier.
- A specially adapted R-Core transformer and 26000uF filter capacitors used in the power supply ensure that the circuits are provided with fast and stable power.
- "In addition to the headphone outputs, the AMG HPA also has 2 sets (XLR and RCA) of analog outputs where it can be used as a reference-level preamplifier with 1MΩ inputs."
