Featuring a compact yet fully functional 50-watt stereo amplifier and a pair of specially designed 2-way desktop speakers, the MXA70 is said to provide the most optimal sound quality whether you are entertaining a small group or seeking a more individual listening experience. The speakers, finished in a luxurious, high gloss piano black, feature select driver elements housed in custom cast aluminum cabinetry to achieve an unusually rich and full sized level of performance for their size. For an even larger sound, connections for a powered subwoofer are available.

Six inputs provide you the flexibility to connect a variety of your music sources; four of the inputs are digital and allow the McIntosh Digital Engine to decode your digital music at up to 32 bits and 192kHz for maximum analog fidelity and enjoyment.

For those times when you want to enjoy your music in a more intimate way, the MXA70 includes a dedicated headphone amplifier that takes advantage of unique McIntosh technologies so that every headphone - from ear buds to studio quality phones - will yield the best possible personal listening experience. McIntosh claims their new Headphone Crossfeed Director (HXD) enables high quality recordings to image like conventional speakers in your headphones, bringing new dimensions to your music.

The MXA70's compact size gives you choice and flexibility when deciding where to place it in your room. It appears to make a great audio system for your office, bedroom or vacation house assuming you could afford its rather luxurious price. Their Power Guard circuitry is designed to prevent clipping that could damage your headphones or speakers, while a 5 Step Bass Boost Control allows for further tonal customization. The amplifier is housed in a beautifully polished stainless steel chassis that not only compliments the classic glass front panel, knobs, brushed aluminum end caps and gloss black speakers, but also blends nicely with any room decor.
