Key Features
Refined Class D amplification
A newly revised negative-feedback circuit is designed to improve the definition of musical detail and the precision of soundstage imaging. The design focuses on reproducing distinct sound textures and clearly locating voices and instruments within the listening space.
High-current energy reserves and fast transient response
Large-capacity power-supply capacitors and low-impedance current paths support rapid energy delivery to the amplifier stages. Local reservoir capacitors connect directly to the power-amplifier supply circuitry, helping meet the sudden current demands of percussion, deep bass, and dynamic movie effects.
550 kHz switching frequency
The Class D output stage operates at a switching frequency of 550 kHz. This high-frequency switching architecture supports efficient power conversion.
1400 W GaN power supply
Nuprime proprietary gallium nitride (GaN) power-supply module provides a total power-supply output capability of 1400 W. It combines power factor correction (PFC) with an LLC resonant conversion stage to support efficient power delivery. The low-noise supply design helps maintain a quiet background, allowing subtle detail and spatial information to remain audible.
Sixth-generation MOSFET technology
The Class D amplifier stages use sixth-generation MOSFETs optimized for fast switching, low conduction losses, and low switching losses. Reducing these losses limits heat generation and supports efficient, reliable operation during demanding playback.
Low-distortion amplifier modules and high-current filtering
New amplifier circuitry is designed for accurate, low-distortion reproduction. The high-frequency output-filter stage uses components rated for 15 A to handle substantial current while attenuating switching energy. Together with the power-distribution design, this helps limit unwanted interaction between channels during complex multi-channel playback.
Substantial output and low-impedance drive capability
Specified output is 170 W (RMS) per channel into 8 ohms and 290 W (RMS) per channel into 4 ohms. The design supports speaker loads down to 3 ohms, with the ability to accommodate brief impedance dips to 2 ohms.
Independent protection for each channel
Each channel incorporates its own protection circuit, designed to disconnect the speaker output quickly when an abnormal operating condition is detected. This provides protection at the individual channel level.
Fully balanced input circuitry
A fully balanced input stage helps reject noise picked up along the signal cable. This is particularly useful with longer cable runs, helping preserve a clean signal between the source or processor and the amplifier.
