DMA-300 RS

About the DMA-300 RS

The Spectral Audio DMA 300 RS is a reference standard stereo power amplifier featuring cutting-edge component technologies including custom semiconductor devices, ultra-precision passive components, and exotic film capacitors. It delivers continuous power output of 225 Watts RMS at 8 ohms, 410 Watts at 4 ohms, and 615 Watts at 2 ohms, with a peak output current of 60 Amps per channel. The amplifier boasts a frequency response of ±0.1 dB from DC to 150 KHz and extremely low distortion levels (less than 0.015% static distortion from DC to 100 KHz). It achieves a slew rate of 600 volts/microsecond and a signal-to-noise ratio of 97 dB unweighted, 107 dB ASA A. The DMA 300 RS uses advanced SHHA driver technology for ultra-fast transient resolution and parts-per-million waveform accuracy, resulting in a natural, immersive listening experience with virtually no signal memory or distortion artifacts. It is hand-built in limited quantities due to its complex and costly construction. The amplifier weighs 29 kg and measures 482 x 184 x 458 mm. It supports multiple line voltages (100, 120, 220 volts) and consumes up to 1600 Watts at maximum power. This model is no longer in production but remains highly regarded in the audiophile community.
