A formidable electronic to celebrate a milestone of a legendary brand: the 75th anniversary from the founding of McIntosh, one of the most respected names in the entire history of High End audio. This is how it is defined monophonic power stage MC2.1KW, proudly presented at the last CES in Las Vegas as the most powerful amplifier never created by the New York company and, above all, the ultimate expression of the concept of unlimited strength and refinement at the service of sound reproduction in capital letters in the home. Substitute From the fabulous MC2KW, also of monophonic type, which was released in 2005, the new McIntosh is a genuine fruit of passion and the search for perfection that takes advantage of a unique experience of three quarters of a century in design of components of exception audio. The objective?: to offer unique features in a product that has no comparison in the world market. The MC2.1KW exhibits a unique configuration, as it is made up of three separate chassis in order to deliver a 2,000 watt continuous power Virtually distortion-free over 8, 4 or 2 ohm loads. Specifically, it is an Output Module and two Power Modules, each of the latter housing a amplification electronics 1,000 continuous watts.
Why three modules instead of one? The creators of this spectacular electronics give two compelling reasons in this regard, the first of which is practical, since each module weighs about 54 kilos. The second is more technical, since the use of a single block would require having an industrial-type electrical outlet with the relevant special wiring. How does this system work? First, the audio signal from the source enters the Output Module coming from the preamplifier. Next, an in-phase signal is sent to one of the Power Modules and it is amplified; at the same time, a out of phase (with the phase inverted) is injected into the second Power Module and amplified. At this point, the two amplified signals leave the Power Modules and are reintroduced into the Output Module, where they excite opposite ends of a McIntosh Autoformer with hand-made bifilar windings. This allows combine waveforms mentioned in one, sjoining the powers corresponding, while any possible noise is reduced to its minimum expression or even completely canceled. Thanks to this engineering strategy, named Quad Balanced and which can also be found in other embodiments of the American firm, the signal that leaves the Output Module exhibits a Extraordinarily low distortion which translates into a sound unparalleled transparency.
The MC2.1KW incorporates a veritable army of technical innovations with respect to its predecessor, it is worth highlighting the use, in the Power Modules just behind the dedicated power block, filtering capacitors significantly larger in order to improve bass response and dynamic range. Among other additions worth mentioning, we should highlight the widespread use of modern components and signal pathsl shortened, as well as the robust wiring with IP60 certification and bayonet connectors that join the different blocks together. In regards to critical thermal dissipation, each Power Module includes four of the exclusive Monogrammed Heatsinks from McIntosh, in which the use of materials with excellent heat conduction properties facilitates the quick evacuation of the excess calories generated by the latest generation high current transistors attached to them. In the area of connectivitytwo sets of balanced and unbalanced line inputs are available, as well as Solid Cinch terminals Separate gold plated for 8, 4 and 2 ohms intended to facilitate the connection (in bi or tri-wiring) of the associated speaker. Likewise, and in line with what is usual in McIntosh amplifiers, the MC2.1KW is equipped with the exclusive and widely contrasted protection systems Power Guard and Sentry Monitor of the American firm. This sensational power amplifier is completed with a top-level mechanical construction and a unique aesthetic that is finished off, although only for the first 75 pairs sold in each of the countries in which McIntosh is present, by elegant badges that pay tribute to the 75th anniversary of the brand.
