Transform Your Home Theater with the McIntosh MC257 7-Channel Amplifier

The McIntosh MC257 7-Channel Solid State Amplifier delivers the power and performance that your home theater deserves. With 250 Watts per channel for 3 channels and 200 Watts per channel for 7 channels, the MC257 ensures your movies, music, and games are brought to life with the unparalleled sound quality and clarity that only McIntosh can provide.

Key Features:

  • 250 Watts x 3 Channels; 200 Watts x 7 Channels
  • Innovative TripleView™ Power Output Meter
  • 94% increase in dynamic headroom for enhanced performance
  • Dynamic Power Manager® (DPM) for consistent power delivery
  • Power Guard® and Sentry Monitor™ for advanced speaker protection
  • Monogrammed Heatsinks™ for cool, quiet operation
  • Gold-plated binding posts to prevent corrosion

Experience Immersive Sound with TripleView™ Technology

The MC257 is highlighted by our eye-catching TripleView™ Power Output Meter, which independently displays the real-time power output of the amplifier’s three front channels. This 15” wide meter combines three traditional McIntosh meters into a single, streamlined enclosure, delivering the same high performance and enticing motion that McIntosh meters are known for. The TripleView meter’s captivating blue glow can be turned off to ensure it doesn’t compete with your TV or movie screen, allowing you to fully immerse yourself in the action.

Pair with the McIntosh MX180 A/V Processor

For the ultimate home theater setup, pair the MC257 with the McIntosh MX180 A/V Processor. This combination "checked all the performance-related boxes when it came to signal integrity and immersion. Also, clarity and dynamics were off the charts... It had an amazing surround bubble that put me in the center of the action. This soundscape featured pinpoint imaging of all the discrete effects. The overall clarity, dynamic punch, and low distortion of the sound were above reproach." – SECRETS of Home Theater and High Fidelity

Powerful Performance with Enhanced Dynamic Headroom

The MC257 has been upgraded to deliver even more power and performance. When using the front left, center, and right channels, power output has been increased by 25%, delivering 250 Watts per channel. When all 7 channels are in use, each receives a robust 200 Watts per channel. Thanks to an increased filter capacity, the MC257 boasts a 94% increase in dynamic headroom, allowing it to handle even the most demanding soundtracks with ease. This increased headroom, along with improved low-frequency performance, ensures that your home theater delivers the impactful, immersive sound you crave.

Advanced Cooling and Quiet Operation

The MC257 operates cool and quiet, thanks to five McIntosh Monogrammed Heatsinks™ connected to advanced high-current output transistors. These features eliminate the need for noisy cooling fans, ensuring that nothing interferes with your movie’s soundtrack. A specially wound toroidal isolation power transformer further minimizes noise, while gold-plated binding posts ensure a pristine signal is sent to your speakers.

Flexible Configuration Options

The MC257 is incredibly versatile and can be used in various home theater configurations. It can power a full 7-channel setup on its own, or it can be paired with additional McIntosh amplifiers, such as the MI128 or MI254, to power systems with more than 7 channels. Alternatively, the MC257 can be used in a 5-channel setup, with the remaining 2 channels available to power a second audio zone in your home.

Classic McIntosh Design

As with all McIntosh products, the MC257 features the classic McIntosh design, including a polished stainless steel chassis, black glass front panel, TripleView meter, illuminated logo, control knobs, and aluminum end caps. This amplifier is as visually stunning as it is powerful, making it the perfect centerpiece for any high-end home theater.

Great for the price you pay
Size: 16.5 Inch, Color: Rustic Brown, Size: 16.5 Inch, Color: Rustic Brown
Great shelves for the price you pay. They look good and seem to have good stability so far; we’ll see if anything falls on heads. I put a 6 pack of each up in my son’s rooms and they have all kinds of stuff from katanas to books to knick knacks on them. The shelves aren’t finished so they can leave slivers and might be harder to clean with just a cloth. They came with 6 pieces of wood, not pre-drilled or with any marks for holes, a pack of pretty tough brackets, and all mounting hardware. We used a level, hammer, stud finder, tape measure, the provided wall anchors, long and short screws, pencil, 13/64 drill bit, Phillips head bit, and drill. These helped save space and get rid of some of their clutter.

Not the best.
Size: 16.5 Inch, Color: Rustic Brown, Size: 16.5 Inch, Color: Rustic Brown
The wood style is burned wood without any sealant. I would have given a better rating but some of the shelving was bowed which makes it not look as appealing. Pretty easy to install. Definitely will need your impact. I can’t imagine trying to do that with a hand held screwdriver. With the wood being bent the quality isn’t what I would want it to be. It can hold a decent amount of weight. But certainly not made for books. Even with wall anchors. It gives you the option to hang it as shown in its picture or the other way where the supports are flipped.

These are a a great set of floating shelves! They were easy to install, feel sturdy, and look clean and modern on the wall. The set of three is perfect for displaying decor, photos, plants or small storage items while adding extra space without taking up room. Great quality, stylish, and a simple way to upgrade any space. They work perfect for my figurines to be displayed.

Exactly what I needed for my bathroom refresh.
Color: B. Rustic Brown - Americana Farmhouse Style, Number Of Shelves: 2, Size: 22.5inches, Color: B. Rustic Brown - Americana Farmhouse Style, Number Of Shelves: 2, Size: 22.5inches
I bought these floating shelves in the color Rustic Brown to replace a bulky storage shelf that was making my bathroom feel cramped, and they completely transformed the space. The wood finish looks much more expensive than I expected, and once installed they gave the bathroom a clean, modern, spa-like feel without taking up visual space. Installation was straightforward overall. I mounted one screw in the center into a stud and used drywall anchors for the remaining hardware, and the shelves feel very sturdy. They sit flush against the wall and don’t sag or wobble. I especially love how slim they are while still being deep enough to hold everyday bathroom items, decor, candles, skincare, and small baskets. The color worked perfectly with my bathroom vanity and mirror trim, and the floating design instantly made the room look more organized and intentional. Huge upgrade for a small space. Definitely recommend if you want functional storage that also looks elevated and minimalist.
