Dragonfire Acoustics MD-4 Amplifier

In stock

Built into a matching anodized aluminum enclosure, the Dragonfire Acoustics MD-4 is a hand-crafted class-D DAC/AMP/DSP system controller featuring audiophile-grade AD/DA conversion through its balanced XLR, SPDIF, and USB inputs.

An advanced DSP engine for speaker calibration offers a total of 120 parametric filters for equalization with crossovers, delays, phase correction, compression, and limiting.

The MD-4 amplifier delivers 250 watts RMS, 1kW peak per channel of full-spectrum power from 1-to-100kHz, and when combined with the drivers’ 100dB/W efficiency accurately and precisely reproduces music at any comfortable listening level.

Free of high-frequency damping networks, the MD-4 amplifier maintains an extremely high-voltage rail-to-RMS-power-rating-ratio at over 93% efficiency. This ensures minimal cooling requirements and maximum long-term reliability.

For improved imaging and to meet the current draw demands of even the most dynamically challenging content, the MD-4 includes two supplementary dual high-capacitance power reserves.

The Dragonfire MD-4 features an industry-leading 119dB signal-to-noise ratio, +26dB of available gain, and below 0.005% total harmonic distortion.

The Power Factor Correction Power Supply ensures universally-adaptable and fully-regulated AC mains operation anywhere in the world.

In a 2.1 Mini Dragon Speaker System, two channels of amplification are dedicated to the stereo pair while the third and fourth channels are summed to integrate with a range of passive subwoofer options.
