Welche Kopfhörer-Anschlüsse hat der NuPrime AMG HPA?

Der AMG HPA bietet gleich drei Kopfhörerausgänge: 6,3 mm unsymmetrisch sowie 4,4 mm und 4-polig XLR symmetrisch. Zusätzlich gibt es Vorverstärker-Ausgänge über XLR und RCA. Damit treibst du sowohl klassische als auch symmetrisch verkabelte Kopfhörer an.

Wie viel Leistung liefert der AMG HPA?

Über den symmetrischen Ausgang liefert der AMG HPA bis zu 3500 mW an 32 Ohm und 300 mW an 600 Ohm. Auch anspruchsvolle, hochohmige Kopfhörer bringt er damit souverän auf Pegel, ohne früh die Puste zu verlieren.

Kann ich den AMG HPA auch als Vorverstärker nutzen?

Ja. Neben den drei Kopfhörerausgängen besitzt der AMG HPA symmetrische XLR- und unsymmetrische RCA-Ausgänge sowie die hochlineare Muses-72320-Lautstärkeregelung in 100 Stufen. So lässt er sich auch als Vorstufe in eine Kette mit Endstufe und Lautsprechern einbinden.

Passt der AMG HPA zum NuPrime AMG DAC?

Ja, beide gehören zur AMG-Serie und sind als Duo gedacht. Der AMG DAC liefert das gewandelte Signal, der AMG HPA verstärkt es für Kopfhörer. HiFi-Advice beschreibt den HPA zudem als idealen Partner zur AMG STA – mit kräftigem, vollem Klang.

The NuPrime AMG HPA is a balanced, Class-A headphone amplifier with a built-in preamp that combines three headphone outputs with a 100-step Muses 72320 volume control.

In other words: this is the kind of headphone amp that finally does your good headphones justice – and doubles as a preamp on the side. An R-core transformer and pure Class-A operation keep the background calm, so fine details don't get lost in the noise.

Why the AMG HPA?

Class A here means constantly operating amplification without the typical crossover distortion – you hear that as warmth and calm. The R-core transformer provides a clean, stable power supply, which pays off especially during dynamic passages.

The 1 MΩ input impedance accepts analog sources gently and keeps distortion low. And because the whole thing is built symmetrically, the left and right channels stay cleanly separated.

What you get

The AMG HPA covers three headphone worlds at once: 6.3 mm unbalanced for the classic, plus 4.4 mm and 4-pin XLR for balanced-wired headphones. Via the balanced output, up to 3500 mW at 32 ohms are available – plenty of reserve even for high-impedance models.

On the input side, you take in multiple sources via XLR and three RCA pairs. And thanks to preamp outputs (XLR and RCA) plus the fine 100-step Muses 72320 control, the headphone amp becomes your system's preamp whenever you need it.

Who is the AMG HPA for?

For anyone with serious headphones – especially balanced-wired or high-impedance ones – who wants an amplifier that can also work as a preamp. Ideal as a partner to the AMG DAC.

Straight talk: if you only occasionally listen to in-ears on your phone, you don't need these reserves – that would be like driving a sports car just to the mailbox. But as soon as good, demanding headphones enter the picture, the AMG HPA shows its strengths.

Our verdict

The AMG HPA is a grown-up headphone amplifier with the pleasant double role of preamp. HiFi-Advice describes it as the ideal partner to the AMG STA – with powerful bass and a full, harmonically rich sound. We at HD Zürisee in Wädenswil like that it makes itself useful not just on headphones, but throughout the whole chain.
