Awesome team here, super knowledgeable! Provided a superb price on a projector that no big box store could come close to. The shop itself is super cool too. Jeff’s got a ton of awesome movie and music memorabilia.

Had the luxury to visit the store this weekend, we were welcomed by Jeff. Really nice and knowledgeable person in the field of Audio. The amazing setup with high end Mcintosh Amps, Preamp and their speakers changed our perspective on sound even though I am use to Parasound, Marantz, Emotiva, Klipsch & Martin logan products.Now time to start finalizing and narrow down my wish list to build a nice System for myself.Will definitely give them the business for all my future purchases.It’s a blessing to have a store like this in your local community - Treat yourself, go and check them out even if you’re not an audiophile - cos I can guarantee you will get into this hobby for sure.

Loved this place! Jeff spent so much time with me helping me pick the right speakers for my setup. He was very patient with all my questions and he was extremely knowledgeable in all the equipment. While this is an appointment only high end audio store, they didn't act elitist when it came to my setup, and they were very down to earth. This is my new go to place for high end audio.

Hand down the best HiFi audio shop in the entire state! These guys have really spent the time and energy to do it right. If you are in the market for a high end system, or just want to listen to some of the best equipment the industry has to offer, then do yourself a favor and make an appointment.

Description

MC257

7-Channel Solid State Amplifier

  • 250 Watts x 3 Channels; 200 Watts x 7 Channels
  • TripleView™ Power Output Meter
  • 94% increase in Dynamic Headroom
  • Dynamic Power Manager®; Power Guard®
  • Designed for home theaters

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.
In addition to the new TripleView meter, the MC257 features many other upgrades. When using just the front left, center and right channels, power output has been increased by 25% from 200 Watts per channel to 250 Watts per channel. When using all 7 channels, each will receive a healthy 200 Watts per channel. Regardless of how many channels are used, the full 200 or 250 Watts is delivered to either 4 or 8 Ohm speakers via our Dynamic Power Manager® (DPM) technology. Filter capacity has been increased by 20% which has produced an amazing 94% increase in dynamic headroom from 1.7dB to 3.3dB as well as improving low frequency performance – both key features in a home theater amplifier, especially when listening to an energetic soundtrack.
The MC257 comes with five of our McIntosh Monogrammed Heatsinks which are connected to advanced high current output transistors to efficiently and silently cool the amplifier; as a result, noisy cooling fans that can interfere with the movie soundtrack are not needed. A quiet, specially wound toroidal isolation power transformer also helps keep noise to a minimum. Speaker terminals have been updated to our standard gold-plated binding posts that prevent corrosion and ensure a quality signal is sent to your home theater speakers. Our power management system that will turn the amplifier off after a set amount of time when no input signal has been detected has also been added. Finally, the front panel is now lit by direct LED backlighting for improved color accuracy and durability.
Besides all these upgrades, the MC257 comes with steadfast McIntosh technologies like Power Guard® to prevent potential speaker damage caused by clipping and over-driving of the amplifier. Our Sentry Monitor technology protects against short-circuits by disengaging the output stage should the current ever exceed safe operating levels (it then resets automatically when operating conditions return to normal). Both balanced and unbalanced inputs are included to connect the MC257 home theater amplifier to your home theater processor.
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.
