McIntosh’s first foray into hybrid integrated amplifiers is an impressive offering. Its design harks back to the MC275 Vacuum Tube Amplifier with its exposed vacuum tubes and stainless steel chassis. Featuring four vacuum tubes (two 12AX7a and two 12AT7 vacuum tubes), the MA252 combines the capabilities of vacuum tube and solid state circuit design. The combination results in an amplifier that delivers both visually and audibly.
Built with the McIntosh Monogrammed Heatsinks, the MA252 utilizes high current output transistors that eliminate amplifier warm-up time. The MA252 is basically plug-and-play, ready to go at peak operating condition just as soon as you flip the switch. Because the MA252 also features solid state output, it can also employ McIntosh’s patented Power Guard technology. This technology watches output signals and makes real time micro adjustments to prevent overdriving and clipping that can damage your speakers.
The MA252 delivers 100 Watts per channel into 8 Ohm speakers or 160 Watts per channel into 4 Ohm speakers. Its all analog design comes with 2 unbalanced, 1 balanced, and 1 moving magnet input. You can also fine tune its performance with bass and treble controls. And you can add in your subwoofer with a dedicated output.
