Brauche ich zusätzlich eine Phonovorstufe?

Nein. Die Phonostufe für MM- und MC-Tonabnehmer ist bereits eingebaut, inklusive zuschaltbarem Subsonic-Filter gegen Trittschall und Plattenwellen. Der Störabstand liegt bei 85 dB für MM und 65 dB für MC. Sag uns, welches System du fahren möchtest, dann prüfen wir die Anpassung.

Ist der AACento ein reiner Klasse-A-Verstärker?

Nein. Reine Klasse A gibt Audio Analogue nur für den Kopfhörerverstärker an, nicht für die Leistungssektion. Diese arbeitet ohne globale Gegenkopplung an einem 480-VA-Ringkerntransformator. Ein umschaltbares Klasse-A-Konzept über die gesamte Kette findest du im grösseren Modell ABsolute.

Welche Quellen kann ich anschliessen?

Drei unsymmetrische Cinch-Quellen, eine symmetrische XLR-Quelle und einen Plattenspieler am Phonoeingang. Digitale Zuspieler brauchen einen eigenen Wandler davor, denn der AACento hat weder Digitaleingänge noch einen eingebauten DAC. Ein passender externer Wandler lässt sich problemlos an einen der Hochpegeleingänge hängen.

Wie viel Platz braucht der AACento?

Er misst 445 × 92 × 400 mm und wiegt 14 kg, passt also in ein normales Rackfach. Die Tiefe von 40 Zentimetern plus Stecker und Kabel solltest du beim Ausmessen mitrechnen. Etwas Luft nach oben schadet nicht, im Standby bleibt der Verbrauch unter einem Watt.

Warum den Pure AACento in Silber bei HD Zürisee kaufen?

Weil wir aus jahrzehntelanger Praxis wissen, welche Tonabnehmer, Kopfhörer und Lautsprecher mit einem solchen Verstärker harmonieren – und welche nicht. Wir liefern, installieren auf Wunsch bei dir vor Ort und betreuen dich über unsere eigene Technikabteilung auch lange nach dem Kauf.

Quantity

The Audio Analogue Pure AACento is an analogue integrated amplifier without global negative feedback, delivering 100 W into 8 Ω and carrying both an MM/MC phono stage and a dedicated headphone amplifier in pure Class A. Hand-built in Italy.

In natural aluminium, the AACento takes on a lighter, more technical look. Inside, everything stays just as serious: a 480 VA toroidal transformer, relay-based source selection, and a signal path without a single op-amp.

Why the Pure AACento?

Because it brings integrated amplifier, phono preamp and headphone amp together in one chassis, without any of the three ending up an afterthought. The power section delivers 100 W at 8 Ω, 200 W at 4 Ω and 330 W at 2 Ω, with an output impedance of 0.4 Ω. Phono accepts MM and MC with a switchable subsonic filter, and the headphone stage runs in pure Class A without negative feedback, delivering up to 1 W at 32 Ω.

What you hear

Power without hardness. The AACento sounds sonorous and full of colour, yet stays composed even in complex passages, because it never runs out of headroom. Volume is controlled digitally while the signal path stays analogue, so even room-level listening volumes don't collapse. On headphones you hear the same signature, just a shade more intimate.

Who is the Pure AACento for?

For people with a record collection and a good pair of headphones who still want just one box in the rack. Plainly put: if you expect streaming, Bluetooth or digital inputs, you're in the wrong place — everything here is analogue, and a digital source has to be added separately. And if you neither listen to vinyl nor use headphones, you're paying for two full-fledged sections you'll never switch on.

Our verdict

A grown-up, honestly built amplifier with two full-strength extras instead of ten half-hearted ones. If you listen in analogue and value a tidy rack, you get a lot of amplifier for very little shelf space.

Frequently asked questions

Do I need a separate phono preamp as well?

No. The phono stage for MM and MC cartridges is already built in, including a switchable subsonic filter against footfall and warped records. The signal-to-noise ratio is 85 dB for MM and 65 dB for MC. Tell us which cartridge you want to run and we'll check the matching.

Is the AACento a pure Class A amplifier?

No. Audio Analogue specifies pure Class A only for the headphone amplifier, not for the power section. That runs without global negative feedback, off a 480 VA toroidal transformer. A switchable Class A concept across the whole chain is found in the larger ABsolute model.

Which sources can I connect?

Three unbalanced RCA sources, one balanced XLR source, and a turntable at the phono input. Digital sources need their own converter ahead of them, since the AACento has neither digital inputs nor a built-in DAC. A suitable external converter connects easily to one of the line-level inputs.

How much space does the AACento need?

It measures 445 × 92 × 400 mm and weighs 14 kg, so it fits a standard rack shelf. Factor the 40 cm depth plus connectors and cables into your measurements. A little airflow above doesn't hurt, and standby consumption stays under one watt.

Why buy the Pure AACento in Silver from HD Zürisee?

Because decades of practice have taught us which cartridges, headphones and speakers harmonise with an amplifier like this — and which don't. We deliver, install on-site on request, and stay in touch through our own technical department long after the purchase too.
