About the MD90
The Ming Da MD90 is a high-quality mono block tube amplifier that delivers 150 watts of power in ultra-linear push-pull mode and 90 watts in triode mode. It uses two matched pairs of KT90 valves to provide smooth, powerful amplification. The amplifier includes a standby switch to allow a warm-up period before full operation, which helps preserve valve longevity. It features a frequency response of 20Hz to 40kHz ±1dB, input sensitivity of 1200mV, input impedance of 100K, and a signal-to-noise ratio of 98dB. The outputs are gold-plated 4mm posts, and the input is a gold-plated RCA phono connector. The MD90 is supplied in pairs for stereo setups and is appreciated for its silky smooth sound and robust power output.
