DMA-150 S2

About the DMA-150 S2

The Spectral DMA-150 S2 is a dual monaural stereo power amplifier designed for audiophiles and professional studio use. It features a fully balanced topology using FET and high-speed bipolar transistors to achieve high-current launch and ultra-fast settling capability. The amplifier delivers 150 watts RMS per channel into 8 ohms, 300 watts into 4 ohms, and 570 watts into 2 ohms, with a peak output current of 60 amps per channel. It has a frequency response of DC to 150 kHz with ±0.1 dB flatness, total harmonic distortion of 0.015%, and a signal-to-noise ratio of 107 dB. The input sensitivity is 1.5 volts nominal, and the amplifier supports speaker loads down to 2 ohms. The DMA-150 S2 uses a vertical dimensional topology with distributed power supply capacitors and individual high isolation transformer windings for each output device, ensuring exceptional sonic transparency, speed, and control. It weighs approximately 28 kg (62 lbs) and measures 482.2 x 184 x 458 mm (19" x 7 1/4" x 18"). This amplifier is highly regarded for its musical resolution, sonic holography, and reliability in demanding audio systems and studios.
