In an era of flashy specs and lifestyle branding, the MC830 stands out because it delivers on fundamentals: power, fidelity, build quality and longevity. For those who seek immersive, high-resolution music playback or commanding home theatre performance — this isn’t just another amplifier; it’s a statement piece. By matching it with a high-quality preamp, source components, and well-matched loudspeakers, you’re investing in an experience, not just hardware.

Whether you’re powering a high-end two-channel system or building a premium home theatre setup, the MC830 delivers exceptional control, transparency and raw power — just the way McIntosh has done for decades.

The McIntosh MC830 is a 1-channel solid-state amplifier designed to bring maximum performance to serious audio systems. Key features include:

• Power output: 300 watts into 8 ohms, and 480 watts into 4 ohms — enough muscle to drive demanding loudspeakers with ease. 

• Precision and clarity: Total harmonic distortion as low as 0.005 %. Signal-to-noise ratio: balanced 120 dB, unbalanced 118 dB. 

• Robust build & refined design: A polished stainless-steel open-chassis design with McIntosh’s signature Monogrammed Heatsinks™, black-glass front panel, illuminated logo and analog dual-scale watt meter. 

• High-end connectivity & protection:

  • Balanced (XLR) and unbalanced (RCA) inputs for flexible system integration. 

  • Patented Power Guard® technology which monitors output signal and makes real-time adjustments to prevent clipping and protect speakers.  

  • Sentry Monitor™ fuse-less protection circuit automatically disengages the output stage if current exceeds safe levels.  

  • Gold-plated Solid Cinch™ speaker binding posts to secure connections and reduce corrosion over time.  

  • Power Control ports and selectable Auto-Off feature (automatically powers down after approx. 30 minutes of no input).  

• Performance specs:

  • Frequency response: +0, –0.25 dB from 20 Hz to 20 kHz, –3 dB down to 100 kHz.  

  • Damping factor >100 wideband.  

  • Dimensions: ~31.2 cm (W) × 24.1 cm (H) × 40.6 cm (D) and weight ~21.8 kg (48 lbs).
