McIntosh MC2500: Classic solid-state stereo power amplifier
The McIntosh MC2500 is an iconic solid-state stereo power amplifier from the American manufacturer McIntosh, now listed as a legacy (discontinued) product.
Built between 1980 and 1990 as part of McIntosh’s high-end power amplifier range, its rugged construction and massive power delivery made it a favourite in recording studios, professional sound systems, and high-level home audio setups.
This model features McIntosh’s signature output autoformers, which ensure excellent impedance matching with a wide variety of loudspeakers, preserving signal integrity and maintaining firm, controlled bass.
Performance and power
Stereo output power: 500 W per channel into 8 Ω
Bridged mono output power: 1,000 W into 8 Ω
Frequency response: 10 Hz – 100 kHz
Total harmonic distortion (THD): ≤ 0.02 %
Damping factor: approx. 30
Input sensitivity: 0.75 V
Signal-to-noise ratio: ~95 dB
Loudspeaker load impedance: 1 Ω – 8 Ω
This performance places the MC2500 firmly in the reference category of its era, with huge drive capability for demanding speakers and the ability to deliver dynamics at high listening levels without audible compression.
Physical characteristics and design
Type: Solid-state stereo power amplifier (transistor)
Cooling: Rear-mounted cooling fans with thermal control (McIntosh design for continuous operation)
Dimensions: approx. 483 × 267 × 432 mm (W × H × D)
Weight: approx. 58.5 kg
Finish: Black/anodised front panel
The industrial design—front panel with large meters, heavy-duty chassis, and robust construction—has long been a McIntosh hallmark, contributing to the amplifier’s longevity and thermal stability.
Use and legacy
Today, the MC2500 is highly prized by collectors, audiophiles and professionals alike for its rock-solid power delivery, durable build and authoritative sonic character that remains desirable decades after production ended.
Although discontinued, its reputation and performance still place it among the benchmark vintage high-end power amplifiers.
McIntosh C2700: Tube Preamplifier
16 inputs in total (9 analog + 7 digital)
5 × 12AX7A tubes and 1 × 12AT7 tube
Supports up to DSD512
Includes DA2 digital audio module as standard
Following a long line of acclaimed McIntosh tube preamplifiers, the McIntosh C2700 combines classic tube musicality with the brand’s most advanced digital capabilities. Using McIntosh’s proven vacuum tube topology, the C2700 integrates the DA2 digital module to bring together state-of-the-art analog and digital sources in a single reference component.
DA2 Digital Audio Module
Successor to the DA1, the DA2 significantly expands the C2700’s digital capabilities. It provides a total of 7 digital inputs:
2 × coaxial digital inputs
2 × optical digital inputs
1 × USB-DAC port
1 × McIntosh-exclusive MCT input
1 × new HDMI Audio Return Channel (ARC) input (audio only)
ARC-compatible TVs can be connected directly to the C2700 to route TV sound through your high-fidelity system. Multichannel Dolby® and DTS® formats are accepted and converted accurately to 2-channel stereo. When CEC is enabled, the TV remote can control power on/off and volume of the C2700.
Via USB, the DA2 supports DSD playback up to DSD512, improving upon the DA1’s DSD256 limit. It uses a new-generation 32-bit Quad Balanced DAC with improved dynamic range and lower total harmonic distortion. Coaxial and optical inputs support up to 24-bit / 192 kHz, while the MCT input ensures the best possible SACD playback from compatible McIntosh transports.
Analog section
For analog sources, the C2700 offers 9 inputs:
3 × balanced XLR pairs
4 × unbalanced RCA pairs
1 × MC phono input (moving coil)
1 × MM phono input (moving magnet)
A dual-chassis layout physically separates analog and digital sections to preserve signal purity. Outputs include 3 variable balanced XLR pairs, 3 variable unbalanced RCA pairs, and 1 fixed unbalanced RCA pair.
Additional features
Bass and treble tone controls adjustable in 2 dB steps
6.35 mm headphone output with High Drive headphone amplifier capable of driving practically any headphones
Headphone Crossfeed Director (HXD®) for a more natural soundstage with headphones
Home Theater Pass Through for seamless integration into AV systems
Power control and data ports for managing other McIntosh components
Roon Tested certification
All this is housed in classic McIntosh styling: black glass front panel with backlighting, blue meters, illuminated logo, metal control knobs and a polished stainless-steel chassis. The tubes are visible through a glass window on the top panel.
