Notable Features

• NuPrime breakthrough Only Distortion Cancellation (ODC) Class D design.

• Preamp stage and Class D oscillation circuit utilizing high-end NJR MUSES8820 op-amp.

• 650KHz high-speed switching frequency allows greater resolution to be achieved.

• The 550W high-power ultra-thin toroidal transformer power supply has been enhanced to deliver cleaner and more stable power with lower noise floor. The entire power path fully adopts 40A ultra-high current and low resistance terminals. Improve current dynamic capability. Total of 52,000uF power supply filter capacitors.

• High quality copper PCB trace instead of usual cables are used to connect the power supply to the amplifier’s circuitry, maximizing power delivery.

• Hybrid Class-D technology that retains the merits of both Class-A and Class-D amplification.

• A stereo amplifier with dual mono implementation.

The Evolution STA sound characteristics can be described as:

• Wider and deeper soundstage with no loss of clarity at the greatest depth. With large scale orchestral recordings, you will be able to have a clear image of the last rows of percussion and wind, even the subtle pedal sounds! Such details are presented in a truthful manner without artificial enhancements.

• Faster dynamics with greater range

• Natural and pure due to ultra-low distortion

• Cleaner background that provides greater detail and nuances

• Class-A like warmth
