McIntosh C12000 & ST 12000 AN

Description 

The McIntosh C12000 is a cutting-edge 2-channel preamplifier that seamlessly blends vacuum tube warmth with solid-state precision through its innovative Hybrid Drive™ technology. Designed for discerning audiophiles, it allows users to choose between tube or solid-state outputs, tailoring the sound signature to their listening preferences.

Engineered with separate audio and control sections, the C12000 ensures exceptional signal purity and isolation, minimizing noise and interference. It features a remarkable 12 analog inputs, including two fully configurable phono inputs, making it versatile for both digital and analog sources.

With fully balanced circuitry throughout, the C12000 delivers pristine sound with exceptional channel separation and dynamic range. This flagship preamplifier is the perfect fusion of classic analog warmth and modern audio engineering—an ideal centerpiece for a high-end stereo system.

Dual-Chassis Design for Maximum Purity

The McIntosh C12000 adopts a rare and highly effective *dual-chassis architecture, separating control functions from the audio circuitry. This design includes the **C12000 Controller* and the *C12000 Preamplifier module, connected via custom high-performance shielded umbilical cables. This total isolation eliminates interference between power/control signals and audio signals, resulting in **ultra-pure sound reproduction. Each left and right audio channel is powered independently, providing **true dual-mono operation* and extraordinary stereo separation.

 Hybrid Drive Technology: Tube and Solid-State in One

McIntosh’s signature Hybrid Drive technology brings together the best of both audio worlds—warm, musical vacuum tube sound and precise solid-state performance. Users can easily switch between solid-state and tube output depending on the genre, source, or personal preference. Six vacuum tubes (two 12AT7 and one 12AX7A per channel) power the high-level tube output, while discrete balanced op-amps handle the solid-state output. This flexibility allows audiophiles to customize their listening experience like never before.

Flexible Analog Connectivity with Configurable Phono Stage

The C12000 Preamplifier module includes 12 analog inputs: six balanced, four unbalanced, and two phono inputs, each configurable for Moving Magnet (MM) or Moving Coil (MC) cartridges. Adjustments for capacitance, resistance, and gain (40–64 dB in 6 dB steps) offer unmatched cartridge compatibility and fine-tuning for any vinyl setup. The phono stage uses a fully balanced configuration with four 12AX7A tubes, delivering rich analog sound with McIntosh’s trademark musicality.

Extensive Output Options for Total System Control

To suit a wide range of setups, the C12000 offers four analog outputs: one balanced tube, one balanced solid-state, one fixed unbalanced, and one programmable unbalanced output (tube or solid-state). All outputs are driven by independent amplifier stages for optimal performance. Whether you're running a McIntosh power amplifier or integrating third-party components, this range of outputs offers total system flexibility.

Headphone Listening and Home Theater Integration

For personal audio lovers, the C12000 includes a High Drive headphone amplifier, compatible with a wide range of headphones. McIntosh’s Headphone Crossfeed Director (HXD®) enhances spatial imaging for more natural sound during headphone listening. Additionally, the Home Theater Pass Through feature allows the C12000 to function seamlessly within a multichannel surround system, making it a perfect hybrid of hi-fi and cinema control.

Engineering Excellence and Iconic Aesthetics

Every element of the C12000 reflects McIntosh’s commitment to craftsmanship and performance. The chassis is made of mirror-polished stainless steel with brushed black titanium accents, housing classic McIntosh elements like blue watt meters, illuminated logos, and custom machined aluminum knobs. Internally, the unit uses fully balanced circuitry throughout, minimizing noise and distortion for exceptional signal fidelity.

Award-Winning Performance

Praised by critics and enthusiasts alike, the C12000 was named "Preamplifier of the Year 2023" by Australian Hi-Fi Magazine. Reviewers highlight its sonic neutrality, low distortion, flexible configuration, and advanced engineering. Whether playing vinyl or streaming high-res digital audio, the C12000 allows you to experience music exactly as it was intended.C12000 2-Channel Solid State and Vacuum Tube Preamplifier with

McIntosh C12000 2-Channel Solid State and Vacuum Tube Preamplifier

The McIntosh C12000 is a flagship two-chassis preamplifier system that combines state-of-the-art engineering, hybrid analog technology, and uncompromising audio fidelity. Designed for discerning audiophiles, the C12000 is built to deliver the most natural and customizable listening experience possible.

Two-Chassis Architecture for Sonic Purity

The C12000 is made up of two separate but integrally connected units: the C12000 Controller and the C12000 Preamplifier module. This dual-box design allows the audio signal path to be completely isolated from power control and data functions. All external connections, control ports, and power regulation reside in the Controller unit, while all audio circuitry is housed in the Preamplifier unit.

Each audio channel is treated independently, with dual isolated power supplies and full electrical and mechanical channel separation, allowing true dual-mono operation. The two units are connected by a pair of high-performance, shielded umbilical cables to prevent any noise intrusion, ensuring unrivaled stereo separation and sonic clarity.

Hybrid Drive Technology: The Best of Tubes and Solid-State

At the core of the C12000 lies McIntosh’s Hybrid Drive technology, giving users the choice between vacuum tube warmth and  solid-state precision. The high-level preamp section uses six vacuum tubes—two 12AT7s and one 12AX7A per channel—to power the tube output. For those who prefer a more neutral signature, the solid-state path uses a discrete balanced op-amp to deliver clear and transparent sound. This hybrid configuration allows users to match the output to their music preferences, system synergy, or even mood—making it one of the most versatile preamplifiers on the market.

High-Performance Phono Stage

The C12000 takes vinyl playback seriously, offering two configurable phono inputs that support both Moving Coil (MC) and Moving Magnet (MM) cartridges. Unlike traditional designs, these inputs are fully customizable with adjustable capacitance, resistance loading, and gain (40–64 dB in 6 dB steps). This level of flexibility ensures precise matching with a wide variety of cartridges and records, making the most of your analog source collection. All phono stages are powered by four 12AX7A tubes in a fully balanced configuration, complete with RIAA equalization for accurate and musical vinyl reproduction.

Flexible Input and Output Options

The C12000 includes a total of 12 analog inputs

6 balanced
4 unbalanced
2 phono (configurable)

On the output side, it provides four separate connections to tailor the system to your needs:

1 balanced vacuum tube
1 balanced solid-state
1 fixed unbalanced
1 programmable unbalanced (can be set as tube or solid-state)

All outputs are driven by discrete amplifiers, maintaining maximum signal integrity and customization across your entire audio chain.
