Mcintosh Labs MA8950 – 2 Channel Integrated Amplifier

McIntosh MA8950 – 2-Channel Integrated Amplifier

The McIntosh MA8950 combines a full preamplifier and a 200 watt per channel power amplifier in a single solid-state chassis, built around McIntosh Autoformer output technology and the DA2 Digital Audio Module. It is a complete two-channel control centre: analogue, phono and digital sources all connect here, and the amplifier delivers its rated power into 2, 4 or 8 ohm loudspeakers without the output falling away into difficult loads.

Doubled filter capacitance lifts dynamic headroom to 3.1 dB over its predecessor, while the black glass front panel, illuminated blue watt meters and polished stainless steel chassis carry the unmistakable McIntosh presentation.

Key features

• 200 watts per channel into 2, 4 or 8 ohms via Autoformer output stage
• DA2 Digital Audio Module with seven digital inputs, including HDMI ARC
• 32-bit/384 kHz Quad Balanced DAC with DSD and DXD playback over USB
• Separate Moving Coil (adjustable) and Moving Magnet phono inputs
• Six unbalanced and one balanced analogue input, plus Home Theater PassThru
• Five-band analogue tone control, adjustable in 2 dB steps
• High Drive headphone amplifier with Headphone Crossfeed Director (HXD)
• Power Guard and Sentry Monitor protection circuits

Autoformer power, whatever the speaker

Most amplifiers deliver less power as speaker impedance falls, or strain when a loudspeaker presents a complex load. The MA8950 uses Autoformers – output transformers that match the amplifier to the load – so the full 200 watts per channel is available at the 2, 4 and 8 ohm taps alike. For owners of demanding floorstanders, that means consistent control and headroom rather than a specification that only holds with an easy load.

The DA2 digital module

The DA2 module provides two coaxial, two optical, one USB, one MCT and one HDMI ARC input. Its 8-channel, 32-bit/384 kHz Quad Balanced DAC handles PCM to 24-bit/192 kHz over coaxial and optical, and over USB extends to 32-bit/384 kHz PCM with DSD64, DSD128, DSD256, DSD512 and DXD support. The HDMI ARC connection routes television sound through the stereo system, and because DA2 is a module, the digital section can be upgraded as formats evolve.

Analogue sources and vinyl

Analogue provision is equally complete: six unbalanced inputs, one balanced input, a fixed Moving Magnet phono stage and an adjustable-loading Moving Coil phono stage for direct turntable connection. A discrete five-band tone control works at 30 Hz, 250 Hz, 500 Hz, 2 kHz and 10 kHz with plus or minus 12 dB of adjustment, and Home Theater PassThru lets the MA8950 drive the front channels inside a multichannel system without a second volume control in the path.

Built for decades of listening

Total harmonic distortion is rated at 0.005 percent across 20 Hz to 20 kHz, with high-level signal-to-noise of 95 dB. Power Guard monitors the signal to prevent clipping, Sentry Monitor guards against short circuits, and gold-plated binding posts resist corrosion. At 34.1 kg, this is an amplifier bought once and kept – the centre of a serious stereo system.

For listeners who want one component to anchor demanding speakers, vinyl, high-resolution digital and television sound, the MA8950 is the complete answer.
