McIntosh MC257 7-Channel Home Theater Amplifier

Bring your home theater dreams to life with the MC257 7-Channel Power Amplifier. Experience the latest blockbusters along with your favorite movies like never before in your home theater with the sound quality and power only McIntosh can deliver.

The MC257 is highlighted by our new eye-catching TripleView™ Power Output Meter that independently indicates the real time power reading of the amplifier’s three front channels. The easy-to-read, 15” (38 cm) wide TripleView meter design is a streamlined approach to the three individual meters found on our previous generation 7-channel home theater amplifier. Instead of three separate meter windows each housing a single meter, the TripleView features three of our traditional mechanical meters in a single meter enclosure.

While a totally new design, each of the three pointers in the TripleView meter have the same inviting motion that McIntosh meters are known for and perform at the same high level as any of our meters. The captivating look and glow of the TripleView meter is sure to be a conversation starter, but its trademarked blue lighting can be turned off so as not to compete with your TV or movie screen.

The MC257 can be utilized in many ways: it can power a 7-channel home theater by itself; it can be paired with either our MI128 or MI254 digital amplifiers in home theaters that have more than 7-channels; or it can be used in 5-channel home theaters with 2 of its channels available to power a second audio zone in your home.

The MC257 sits on a polished stainless steel chassis and bears the classic McIntosh design of a black glass front panel with the TripleView meter, illuminated logo, control knobs, and aluminum end caps.
