With a muscular 450 WPC into 8 ohms and stunning sonic performance, the DS-450 stereo amplifier provides high performance, high efficiency, and high value. Incredibly dynamic and quick on its feet, it has a big "jump factor." Bass is deep, harmonically rich, and forcefully controlled. The midrange is open, tightly focused and uncannily transparent. Highs are extended, detailed and grainless. You need to hear it for yourself to appreciate its remarkable musicality!
