A private cinema can hide its speakers, but the electronics running them rarely stay modest. The McIntosh MX124 is the New York audio company’s new flagship A/V processor, built to coordinate elaborate 13.4-channel systems while leaving power amplification to separate components.

The architecture supports 7.4.6- or 9.4.4-channel layouts, with four independently managed subwoofer outputs—twice as many as the preceding MX123. Nine 32-bit digital-to-analog converters handle immersive formats including Dolby Atmos, DTS:X Pro, Sony 360 Reality Audio, and MPEG-H Audio. Dirac Live Room Correction, Dirac Live Bass Control, and Audyssey MultEQ XT32 licenses provide several approaches to matching that hardware to the room.

Video connectivity is equally expansive. Seven HDMI inputs and three outputs support 8K/60Hz and 4K/120Hz signals, along with Dolby Vision, HDR10+, HLG, IMAX Enhanced, eARC, VRR, and ALLM. Streaming extends to AirPlay, Qobuz Connect, Spotify Connect, TIDAL Connect, and Roon, with playback up to 32-bit/192kHz.

Its black-glass face and green illumination keep it visually aligned with McIntosh components rather than generic theater hardware, much as the Bang & Olufsen Beosystem 3000c treats audio equipment as part of the room.

McIntosh has not published a price, though U.S. retailers list it at $15,000.
