NuPrime AMG HPA

1MΩ input impedance, high power, and full-balanced design delivering the most transparent and detailed signal with a wide frequency bandwidth and rich harmonics

The AMG HPA is the world’s first headphone amplifier that utilizes the 1MΩ input impedance design, first used in our flagship EVO ONE amplifiers, and now in the AMG series. Adhering to the philosophy of the AMG series, the intention is to deliver the most transparent and detailed signal from the source to the rest of the audio chain. With the intimate listening experience that headphones provide, the stark difference in the level of performance easily demonstrates the advantage of the AMG 1MΩ design.
