{"product_id":"audioanalogueaaphonosilver","title":"Audio Analogue Pure AAPhono Phono Preamplifier, Silver","description":"\u003cp\u003eThe Audio Analogue Pure AAPhono is a phono preamplifier for MM and MC cartridges that brings the turntable signal up to line level and equalises it to the RIAA curve.\u003c\/p\u003e\n\u003cp\u003eThe silver version shows off the brushed aluminium of the Pure AA series openly — anyone who treats their rack as furniture rather than as something to hide usually reaches for this one. Inside, three toroidal transformers do the work, one per channel and one for the control circuitry, cleanly separated from each other.\u003c\/p\u003e\n\n\u003ch2\u003eWhy the Pure AAPhono?\u003c\/h2\u003e\n\u003cp\u003eBecause the most sensitive spot in your system sits between cartridge and amplifier. This is millivolt territory, and any noise added here stays in forever. The AAPhono adds 40 dB for MM and 65 dB for MC, follows the RIAA curve to within ±0.25 dB, and inserts a subsonic filter between the gain stages so rumble and warped records don't occupy the power amp. On top of that comes a DC protection circuit that stops any DC offset from travelling further.\u003c\/p\u003e\n\n\u003ch2\u003eWhat you hear\u003c\/h2\u003e\n\u003cp\u003eFirst, less: less background noise, less harshness in the treble, less mud in the bass. And then more of what's actually in the groove — space, timing, the small details at the tail of a decay. What decides this is matching to your system: MM cartridges want the right capacitance, MC cartridges the right termination resistance. You set both on the unit itself, no soldering iron and no guesswork required.\u003c\/p\u003e\n\n\u003ch3\u003eWho is the Pure AAPhono for?\u003c\/h3\u003e\n\u003cp\u003eFor vinyl listeners whose amplifier has either no phono input at all or one that was clearly built in out of duty — and for anyone who's switched from an MM to an MC cartridge and suddenly notices it sounds quieter and thinner than promised. Plainly put: if you already have an amplifier with a full-fledged phono section, the leap is smaller than the effort might suggest. A better cartridge is then probably the bigger gain.\u003c\/p\u003e\n\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eThe Pure AAPhono is the kind of device you set up once and then forget about — in the best sense. The precondition is that the termination values match your cartridge; get that wrong and even the best phono stage squanders its potential.

If the phono input is missing, nothing works without a separate stage. If one is present, its quality decides how much of the vinyl actually reaches you.\u003c\/p\u003e\n\u003ch3\u003eWhich cartridges suit the Pure AAPhono?\u003c\/h3\u003e\n\u003cp\u003eBoth MM and MC systems, with adjustable termination. For MM you select input capacitance and input resistance, for MC the input resistance — you set the values via buttons on the unit and they stay stored. Tell us your cartridge model and we'll tell you the right setting.\u003c\/p\u003e\n\u003ch3\u003eCan I connect the Pure AAPhono directly to a power amp?\u003c\/h3\u003e\n\u003cp\u003eNo, that doesn't work. The Pure AAPhono delivers a fixed output level and has no volume control — a power amp would immediately play at full volume with it. Between phono stage and power amp there always needs to be a preamp or an integrated amplifier with a line-level input. It has no headphone output either.\u003c\/p\u003e\n\u003ch3\u003eWhere does the Pure AAPhono get connected?\u003c\/h3\u003e\n\u003cp\u003eBetween the turntable and a free line-level input on your amplifier, so AUX, Line or CD. The turntable's ground wire belongs on the ground terminal, otherwise you'll get a hum. That's all there is to it — and if something does hum, it's almost always down to grounding or proximity to the power supply.\u003c\/p\u003e\n\u003ch3\u003eWhy buy the Pure AAPhono from HD Zürisee?\u003c\/h3\u003e\n\u003cp\u003eBecause we tell you beforehand whether the effort is even worthwhile for your chain — rather than just selling you something. HD Zürisee in Wädenswil has worked with vinyl since 1997, knows the usual pitfalls in matching, and has its own technician for installation and fine adjustment.\u003c\/p\u003e\n\n\u003ch2\u003ePairs well with\u003c\/h2\u003e\n\u003cp\u003eVinyl is a team sport: you'll find the selection of \u003ca href=\"\/en\/collections\/plattenspieler\"\u003eTurntables\u003c\/a\u003e and \u003ca href=\"\/en\/collections\/tonabnehmer\"\u003eCartridges\u003c\/a\u003e with us, everything else around the groove under \u003ca href=\"\/en\/collections\/alles-vinyl\"\u003eAll Vinyl\u003c\/a\u003e, and more devices from the range stand in the \u003ca href=\"\/en\/collections\/audio-analogue\"\u003eAudio Analogue world\u003c\/a\u003e.\u003c\/p\u003e","brand":"Audio Analogue","offers":[{"title":"Default Title","offer_id":52989482860880,"sku":"6500","price":2150.0,"currency_code":"CHF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0932\/3262\/8048\/files\/audio-analogue-pure-aaphono-phono-vorverstaerker-silber-frontansicht.jpg?v=1785425652","url":"https:\/\/hdzuerisee.ch\/en\/products\/audioanalogueaaphonosilver","provider":"HD Zürisee AG","version":"1.0","type":"link"}
