McIntosh has announced three new home theater products: the MX170 (pictured above) and MX123 AV Processors and the MC255 5-Channel Home Theater Amplifier.

The 15.1-channel MX170 processor (MSRP $15,500) includes 4K UHD architecture, High Dynamic Range (HDR) capabilities, and immersive audio processing. It has 8 HDMI inputs and 4 HDMI outputs powered by the “most powerful” HDMI processors available. Each HDMI port is HDCP 2.2 and has 18Gbps of bandwidth for 4K Ultra HD and full 4:4:4 color spacing. Audio Return Channel (ARC) is  featured on 3 of the outputs, with the fourth sporting Enhanced Audio Return Channel (eARC) functionality.

HDR formats onboard are HDR10, Dolby Vision and HLG. A special HDBaseT output is included to prevent signal loss or degradation with long distances between the MX170 and the screen. It also has 3D video pass-through.


The $8,000 13.2-channel MX123 processor (pictured directly above), meanwhile, also decodes Dolby Atmos, DTS:X and Auro-3D, and includes 4K UHD processing and upscaling capabilities. The 13.2 discrete channels are available with balanced and unbalanced audio outputs, and there are two additional unbalanced outputs for further connection flexibility.

Both DSD and ALAC playback support have been doubled to DSD128 and ALAC 192kHz for better high resolution audio performance, according to McIntosh. The also MX123 has 7 HDMI inputs and 3 HDMI outputs, all of which are HDCP 2.3 compatible. They all also have 18Gbps of bandwidth to support HDR formats Dolby Vision, HDR10 and HLG, 4K Ultra HD at 50/60Hz, 4:4:4 color spacing, Rec. 2020, and 3D video pass-through. Enhanced Audio Return Channel (eARC) functionality is included on one of the HDMI outputs.


Lastly, McInstosh has rounded out this new series of offerings with an $8,000 5-channel home theater amp (above), the MC255, which includes McIntosh’s new TripleView Power Output Meter for independently indicating real time power reading of the amplifier’s three front channels. McIntosh also claims to have doubled dynamic headroom and power output is rated at 250 WPC.
