Works perfectly, one-owner with original packing material and box, calibration microphone and cable, remote control and manual. Very little use.

The McIntosh MX180 A/V Processor is a world-class, ultra-premium 16-channel home theater hub built for high-end cinematic setups. Retailing at $21,000, it builds upon its predecessor (the MX170) by introducing comprehensive 8K video processing alongside its legendary audiophile-grade acoustic engineering. [1, 2, 3, 4, 5]Key Performance Strengths

• Lyngdorf RoomPerfect Calibration: Reviewers on community forums like Audiogon rank RoomPerfect as an industry-best calibration software. It corrects for harsh room acoustics (like glass walls) without changing the natural tonal characteristics of your speakers. [1, 2, 3]
• True Audiophile Music Performance: Unlike mainstream home theater processors that sound "boxy" or compressed during stereo music listening, the MX180 excels at preserving dynamic micro-details. [1, 2]
• Immense Soundstage: Users trading up from older platforms report that expanding their system to a 9.1.4 or 15.1 layout yields massive leaps in center-channel vocal clarity and ambient panning. [1, 2]
• Cooler Operations: Thanks to updated processing architecture, the unit runs significantly cooler than past McIntosh processors, ensuring long-term hardware reliability. [1, 2]
