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, ARC was 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.
