PureAA

AAcento
Integrated amplifier

AAcento is the only amplifier in the PureAA line. This line of products was created to recall the philosophy used in the most successful Audio Analogue products: the simple design together with the reference sound performance to create products with the best value for money available on the market.

Thanks to the collaboration with Airtech laboratories for the development of the Anniversary line, some ideas have been taken for this new line that unlike the Anniversary line, where each model was created to do in the best way what it was designed for, in the PureAA line, the goal is also to make products with a wider number of functions and connections in order to attract the interest of users who seek these features in a single product.

This is simple to understand by looking at the functions described here, as well as it is easy to understand that everything has been done with extreme care and uncompromising solutions, very difficult to find in products of this category and price range.

The simple design together with the reference sound performance, are the combination of a product with the best value for money available on the market

480W toroidal transformer produced specifically for AAcento, zero global feedback both in the preamp section and in the power stage, digital volume control without the use of op amps, relay input selector to minimize non-linearities, oversized SMD resistances to minimize induced thermal distortion, MM/MC phono input with insertable subsonic filter, pure class A headphone amplifier on board, native differential input, Direct mode to use the device as power amplifier in a home theater system, controls managed by microcontroller with proprietary software, channel balancing control, four different volume scales selectable. Aluminum remote control machined from solid. Available finishes: natural aluminum or satin black.
