{"product_id":"audioanalogueaacentosilver","title":"Audio Analogue Pure AACento Integrated Amplifier, Silver","description":"\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eIn 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.\u003c\/p\u003e\n\n\u003ch2\u003eWhy the Pure AACento?\u003c\/h2\u003e\n\u003cp\u003eBecause 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.\u003c\/p\u003e\n\n\u003ch2\u003eWhat you hear\u003c\/h2\u003e\n\u003cp\u003ePower 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.\u003c\/p\u003e\n\n\u003ch3\u003eWho is the Pure AACento for?\u003c\/h3\u003e\n\u003cp\u003eFor 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.\u003c\/p\u003e\n\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eA 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.

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.\u003c\/p\u003e\n\u003ch3\u003eIs the AACento a pure Class A amplifier?\u003c\/h3\u003e\n\u003cp\u003eNo. 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.\u003c\/p\u003e\n\u003ch3\u003eWhich sources can I connect?\u003c\/h3\u003e\n\u003cp\u003eThree 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.\u003c\/p\u003e\n\u003ch3\u003eHow much space does the AACento need?\u003c\/h3\u003e\n\u003cp\u003eIt 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.\u003c\/p\u003e\n\u003ch3\u003eWhy buy the Pure AACento in Silver from HD Zürisee?\u003c\/h3\u003e\n\u003cp\u003eBecause 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.\u003c\/p\u003e\n\n\u003ch2\u003ePairs well with\u003c\/h2\u003e\n\u003cp\u003eAnalogue sources and converters complete the AACento: browse the \u003ca href=\"\/en\/collections\/plattenspieler\"\u003eTurntables\u003c\/a\u003e and \u003ca href=\"\/en\/collections\/tonabnehmer\"\u003eCartridges\u003c\/a\u003e, add a \u003ca href=\"\/en\/collections\/dac\"\u003eD\/A converter\u003c\/a\u003e if needed, choose your \u003ca href=\"\/en\/collections\/lautsprecher\"\u003eSpeakers\u003c\/a\u003e, or explore the whole \u003ca href=\"\/en\/collections\/audio-analogue\"\u003eAudio Analogue world\u003c\/a\u003e.\u003c\/p\u003e","brand":"Audio Analogue","offers":[{"title":"Default Title","offer_id":52989482729808,"sku":"7500","price":4550.0,"currency_code":"CHF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0932\/3262\/8048\/files\/audio-analogue-pure-aacento-vollverstaerker-silber-frontansicht-2.jpg?v=1785425884","url":"https:\/\/hdzuerisee.ch\/en\/products\/audioanalogueaacentosilver","provider":"HD Zürisee AG","version":"1.0","type":"link"}
