A truly impressive aesthetic due to its elegance and forcefulness constitutes the letter of presentation of the MA12000, an extraordinarily complete stereo integrated amplifier that perfectly reflects McIntosh commitment to engineering and craftsmanship at the highest level.
The MA12000 is a hybrid design that combines a vacuum tube-based preamp section (two 12AX7A per channel) with power amplification circuitry equipped with McIntosh 's exclusive Autoformer technology, which ensures that its 350 continuous watts per channel are delivered in its entirety whether the impedance of the associated speakers is 8, 4 or 2 ohms.
In the area of analog connectivity, the most opulent of McIntosh 's stereo integrated amplifiers includes a total of 10 inputs divided into 2 balanced line, 6 unbalanced line, 1 phono for moving magnet (MM) capsules and 1 phono for moving coil (MC) capsules, to which outputs must be added in balanced and unbalanced formats.
When it comes to digital connectivity, the MA12000 includes as standard McIntosh 's advanced DA2 module, which combines six digital inputs (2 coaxial, 2 optical, 1 USB and 1 MCT) with one HDMI-compatible ARC (Return Channel). Audio) to facilitate the enjoyment of television programs using a single digital connection.
On the other hand, the DA2's DAC functionality is compatible with recordings in DSD512 (22.4 MHz) and DXD with a sample rate of 384 kHz, thanks to the use of an audiophile-grade 8-channel D/A conversion chip. with 32-bit technology configured in Quad Balanced mode with the aim of maximizing dynamic range and minimizing distortion.
Likewise, McIntosh 's exclusive MCT input allows for a secure DSD connection with any of the brand's CD/SACD transport mechanisms and optimizes the sound quality of SACDs.
The MA12000 also includes two of McIntosh 's exclusive Monogrammed Heatsinks to ensure perfect thermal stability of the advanced high-current, high-speed slew transistors in its output section, plus a high-current headphone amplifier. Headphone Crossfeed Director (HXD), powerful electronic protection and two iconic elements of the American firm: the treated glass front panel and two elegant analogue meters with a blue background.
