The C2800 is a sophisticated and very complete reference stereo preamplifier with DAC functionality, based on vacuum tubes and executed with the highest quality components in both the analog and digital fields. Thus, all power supplies are fully regulated, while a transformer with a radial section core (“R-core”) ensures stable and noise-free operation.
For its part, the switching between inputs is electromagnetic, in order to minimize distortion and reduce noise virtually to zero, a scheme that is complemented by a high-precision volume control system (0.1 dB steps). completely balanced.
As far as DAC functionality is concerned, it focuses on McIntosh 's advanced DA2 module, which in addition to ensuring compatibility with PCM files up to 32-bit/384 kHz and DSD up to DSD512 (in both cases via USB), reinforces it with 7 inputs. digital (including an HDMI with ARC and an MCT for connection to the McIntosh SACD transport mechanisms) an analog connectivity consisting of 7 Line and 2 Phono inputs, the latter compatible with moving coil (MC) and moving magnet capsules (MM), to which is added a subwoofer output.
The C55 is completed with the unmistakable industrial design of the New York brand and a traditional tone control (treble and bass) of high precision, it is Roon Tested approved and can be controlled through the powerful McIntosh Connect “app”.
