This is a very slightly used McIntosh integrated amplifier with a hybrid construction including 4 vacuum tubes. The amplifier is practically in an impeccable shape, like new, both technically and physically. 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 thats both visually and sonically stunning. 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. All 4 inputs can be given user-friendly names in order to simplify user control.Bass and treble tone controls help fine tune the music to ones personal preferences. A full range subwoofer output is included for use with a powered subwoofer to further enhance low frequencies. The MA252 features our McIntosh Monogrammed Heatsinks which are connected to advanced high current output transistors. These transistors eliminate the typical amplifier warm-up time so that the MA252 is in peak operating condition from the moment its turned on. A powerful control microprocessor is used for smooth system operation, along with some of the latest audio-grade circuit components that deliver the best possible sound. Thanks to its solid-state output, the MA252 is our first product containing vacuum tubes to include our patented Power Guard® technology. Power Guard monitors the output signal for signs of overdriving and makes real time micro adjustments to the input signal to prevent harsh sounding clipping that could potentially damage the speakers. If Power Guard is activated, the 2 vacuum tubes connected to the affected audio channel(s) will flash an amber color; they will return to their normal green color when the clipping has stopped. 100 Watts into 8 Ohms 160 Watts into 4 Ohms.
