Other Notes: "There are several reasons to choose the DS450M over its stereo counterpart. The most important is performance-based: a monaural amp simply produces a bigger, more spacious soundstage. Also, we were able to fit a much larger power supply in the chassis. Then there is the issue of size: the DS450M is smaller and easier to situate than the hefty DS450 stereo amplifier. In addition to its reduced height, the DS450M mono is 4.15 inches (10.5 cm) shallower, allowing it to fit in a much tighter cabinet space. And, lastly, the DS450M is also perfect for multi-channel home theater systems when you only need one more powerful and dynamic amplifier channel. Rated power is 450 watts into 8 ohms.

The DS450M has the same chassis size as the DSi200 and DS225, and continues the same design philosophy of other Definition Series amplifiers. Our proprietary “hybrid Class D” all-discrete analog switching-mosfet output technology is combined with an enormous linear analog power supply, yielding tremendous speed and power delivery in a compact, cool-running chassis. This remains a distinctive Audio Research design from the ground up, forsaking the use of prepackaged “OEM” solutions common to other switching amplifiers. Each DS450M idles at only 55 watts. One major enhancement that allows a pair of DS450M’s to offer even higher performance than a DS450: the energy storage of a pair of DS450M monoblocks is 1,368 joules, an increase of 62% over the DS450. The immense power supply will jump-start the most inefficient speakers when the music demands it." - Audio Research
