McIntosh MA252 Integrated Amplifier
Combining the warmth of vacuum tubes with the reliability of solid-state design, the McIntosh MA252 Integrated Amplifier is the company's first hybrid integrated amp. Its preamp stage consists of two 12AX7a and two 12AT7 vacuum tubes housed in protective cages, while the output stage is a directly-coupled solid-state unit delivering up to 160 Watts per channel. Two unbalanced, a balanced, and an MM phono input are offered and can be renamed for ease of use. The all-analog design also includes bass and treble controls for fine-tuning and a full-range subwoofer output to boost low-frequency response.
