About the NuPrime-X MCX-800AD
The NuPrime-X MCX-800AD is an eight-channel amplifier with a built-in multichannel DAC, made for immersive music, movies and gaming from a Mac or HDMI sources. Instead of a single multichannel DAC chip, it re-clocks the eight digital channels and decodes them with four DAC chips. Each channel is driven by two Class D amplifiers in bridged mono. At HiFi Boutique it ships free anywhere in the USA, with sales tax already included.
Why Choose the MCX-800AD
After the DACs, a dedicated I-V conversion stage and four OP2134 op-amps, each serving its own channel pairs, keep crosstalk low. NuPrime's own DC converters power the analog (±15V) and digital (+5V) circuits separately.
The amplifier uses NuPrime's Adaptive Voltage Switching power supply: the output signal feeds the supply's servo stage, adjusting the rail voltage for detail at low levels and power at high volume. Each channel is two bridged Class D amplifiers with up to 100kHz bandwidth and dual feedback.
In Stereophile, Kalman Rubinson wrote: "The MCX-800AD was fully competitive. I thought that the NuPrime did everything right. Its voice and instrument rendering was particularly appealing."
