MA9000 Integrated Amplifier
Extremely versatile 2-channel integrated amplifier with 300w per channel
The MA9000 Integrated Amplifier can help you achieve audio perfection. The MA9000 offers 300 Watts per channel and combines our amplifier and preamplifier expertise into one comprehensive unit.
There are enough inputs and outputs on the MA9000 to last a lifetime. The 10 analogue connections are comprised of 2 balanced and 6 unbalanced inputs plus 1 Moving Coil and 1 Moving Magnet for turntable connectivity. Both phono inputs feature adjustable loading for fine tuning of vinyl playback. All unbalanced analogue connectors are made from premium gold-plated solid brass for superior signal handling and grounding.
On the digital side, 2 coax, 2 optical, 1 USB and 1 MCT input (for use with our MCT500 SACD/CD Transport) are all housed in the DA1 Digital Audio Module; the DA1 can be easily replaced by future modules to keep your MA9000 up to date as new digital audio formats and technologies are developed. (NOW AVAILABLE: Optional dealer installed upgrade to the DA2 Digital Audio Module.) The DA1 utilizes a powerful 8-channel, 32-bit Digital-to-Analog Converter (DAC) used in Quad Balanced mode. The coax and optical inputs will decode music up to 24-bit/192kHz for high resolution audio playback; the USB input accepts even higher PCM signals up to 32-bit/384kHz and supports up to DSD256 and DXD 384kHz. All inputs can be given custom names for user-friendly system control and configuration. All inputs also function independently of each other and each is always available for use regardless of how your sources are connected.
The MA9000 features the McIntosh Monogrammed Heatsinks™ that are made from high quality materials with excellent thermal conductivity properties. They are so efficient at dissipating heat that they warrant bearing the McIntosh “Mc” logo. They also have a higher quality finish thanks to a new manufacturing process. They are connected to advanced high current output transistors that eliminate thermal equilibrium lag time (or warm-up time), meaning the first note played will sound just as good as those played later in your listening session.
New, more powerful control microprocessors have been used in the MA9000 to improve overall system operation. Some of the latest audio-grade circuit components have also been utilised to allow the MA9000 to deliver the best sound possible. At 300 Watts per channel, the MA9000 has enough power to properly drive virtually all loudspeakers – and the renowned McIntosh Autoformer™ guarantees your speakers will always receive that full 300 Watts regardless if they have 2, 4 or 8 Ohm impedance.
The MA9000 is one of many McIntosh products to receive Roon Tested designation from Roon Labs. It has been profiled and tested by both Roon and McIntosh for maximum compatibility. Roon will recognize it and send it audio optimised for its capabilities. No fiddling with checkboxes or dropdowns, Roon Tested devices are automatically identified and configured out of the box for a superior customer experience.
