McIntosh MA2375 2-Channel Vacuum Tube Integrated Amplifier
Our first vacuum tube integrated amplifier in over a decade, the MA2375 Vacuum Tube Integrated Amplifier is a statement of uncompromising artistry. Crafted for the music purist but refined for the modern listener, the MA2375 invites you to rediscover your music with amazing clarity and beauty. Every detail, from its polished stainless-steel chassis to the warm glow of its tubes, reflects our legacy of excellence and timeless design. PURE TUBE ARTISTRY This all-analog masterpiece combines a vacuum tube preamplifier with a vacuum tube power amplifier in a single, elegantly designed unit. In the power amplifier section, four KT88 output tubes and four 12AT7 driver tubes deliver 75 watts per channel of effortless, low-distortion power. You will experience a rich, full-bodied sound through virtually any speakers thanks to our Unity Coupled Circuit Output Transformers. The vacuum tube preamplifier portion is powered by two 12AX7A and two 12AT7 preamp tubes. ICONIC STYLING BLENDED WITH MODERN PERFORMANCE The MA2375 effortlessly blends timeless McIntosh design with cutting-edge performance. Dual McIntosh blue watt meters, a polished stainless-steel chassis, and the signature glow of vacuum tubes create an aesthetic as captivating as the sound. A 5-band analog equalizer offers personalized tonal shaping, while the High Drive headphone amplifier with Headphone Crossfeed Director (HXD®) adds dimensionality to private listening. PRECISION MEETS PROTECTION To protect the KT88 output vacuum tubes, our Power Guard Screen Grid Sensor® (SGS) technology continuously monitors the current and adjusts the input signal in real-time to maintain optimal performance and tube integrity. If the current becomes too high, Power Guard SGS® will dynamically attenuate the input signal to keep the vacuum tubes operating at safe levels. Combined with Sentry Monitor™ fuse-less short-circuit protection, the MA2375 is engineered for enduring reliability without compromise. CONNECTION FLEXIBILITY The MA2375 offers an array of analog inputs, including two balanced and three unbalanced connections, to connect music streamers with analog outputs, CD players, tuners, and D/A converters. Connecting a turntable is an easy task via the configurable phono input that can accommodate both Moving Coil and Moving Magnet cartridges. The phono stage includes adjustable Gain, Capacitance, Resistance Loading, and RIAA equalization for optimal vinyl playback. A subwoofer output enables the addition of a powered subwoofer to extend low-frequency performance. Our gold-plated Solid Cinch™ speaker binding posts ensure a secure and corrosion-resistant connection for your speaker cables, while an unbalanced preamp output supports the addition of a second amplifier in advanced multi-zone audio systems. EASY CONTROL AND INTEGRATION Convenience features include Power Control, enabling synchronized power on/off for connected McIntosh components; Home Theater PassThru for seamless integration into a home theater system; and Data Ports to send remote control commands to connected source components. An RS232 port enables advanced control options with third-party systems, or the unit can be operated via the included remote control for ultimate ease of use.
