The MA252 Integrated Amplifier is the first hybrid integrated amplifier from McIntosh. Taking retro design cues from the legendary McIntosh MC275 Vacuum Tube Amplifier, the MA252 combines the best of vacuum tube and solid state circuit design to create an amplifier that’s both visually and sonically stunning.
This beautifully crafted integrated amplifier includes McIntosh's Hybrid Drive™ technology that uses the best of vacuum tubes and solid state to produce the best sound performance. The preamplifier stage uses two 12AX7a and two 12AT7 vacuum tubes housed inside stylish protective cages; the output stage is a direct coupled solid state amplifier that delivers 100 Watts per channel into 8 Ohm speakers or 160 Watts per channel into 4 Ohm speakers. An all analog design, it comes with 2 unbalanced, 1 balanced and 1 Moving Magnet phono input for turntables. All 4 inputs can be given user-friendly names in order to simplify user control. Bass and treble tone controls help fine tune your music to your personal preferences. A full range subwoofer output is included for use with a powered subwoofer to further enhance low frequencies.
