History
The C2700 was introduced in 2016 as McIntosh's new flagship preamplifier, succeeding the C2500. It represented a significant evolution in McIntosh's preamplifier design, incorporating both vacuum tube and solid-state technologies in a hybrid architecture that leveraged the strengths of each. The goal was to create a preamplifier that could serve as the heart of a modern high-end audio system while maintaining the musicality that has defined McIntosh for decades.
Development focused on several key areas: integrating a state-of-the-art digital-to-analog converter, improving the phono stage to handle both moving magnet and moving coil cartridges, and creating a user interface that balanced traditional McIntosh aesthetics with modern functionality. The result was a preamplifier that could handle any source—from vintage vinyl to high-resolution digital—with equal excellence.
Since its introduction, the C2700 has become the reference preamplifier for many of the world's most discerning audio systems. Its combination of traditional McIntosh values with modern technology has made it equally appealing to longtime McIntosh enthusiasts and newcomers to high-end audio.
