About the C70 70th Anniversary
The McIntosh C70 70th Anniversary Vacuum Tube Preamplifier is a limited edition model produced from 2018 to 2020 to celebrate 70 years of McIntosh. It features an all-analog design with a retro look, housed in a polished stainless steel chassis with a black glass front panel inscribed with special 70th Anniversary lettering. The preamplifier uses six vacuum tubes (five 12AX7A and one 12AT7) visible through a glass panel on the top cover. Control operations are performed via knobs and rocker switches, with modern LED indicators for input selection and volume level. It offers seven inputs: two balanced, three unbalanced, one Moving Coil phono, and one Moving Magnet phono input, plus two pairs each of balanced and unbalanced outputs. The unit includes a high-drive headphone amplifier with Headphone Crossfeed Director (HXD®) technology and Power Control ports to automatically turn other McIntosh components on and off. It pairs perfectly with the MC2152 70th Anniversary Vacuum Tube Amplifier and is highly regarded for its sound quality and build.
