The X-A160EVO represents a refined evolution in stereo amplification, featuring upgraded circuitry and power transistors sourced from the acclaimed MAA 1000. Its compartmentalized, rigid chassis provides superior electromagnetic shielding, isolating critical circuits and minimizing interference for cleaner signal integrity. Premium audiophile-grade components deliver nuanced, detailed music reproduction across your collection. Paired with a robust power supply and high-current output transistors (NJW0281G – NJW0302G), the amplifier commands even the most dynamic recordings with authority and control. Rated at 160 watts per channel in class AB operation, the X-A160EVO offers switchable class A biasing for the initial watts—ideal for intimate listening. A rear-panel Hi-Bias switch enables seamless automatic transition to class AB as power demands increase, balancing sonic purity with practical amplification.
