Clearance: NuPrime Audio PRA-9X Pre Amplifier

Ex-Display Product Boxed and in excellent condition - hardly used. Like new! The NuPrime PRA-9X is a fully balanced preamplifier designed for ultra-low distortion (THD+N of 0.0004%) that includes a MM phono input and a 6.3mm headphone output. There are a variety of settings for matching different MM cartridges. NuPrime PRA-9X is a pre-amplifier with a fully balanced design and includes a MM phono input. The input and output use a special audio Relay Switch, which has the lowest interference and highly accurate transmission, to switch the source. The phono input has a variety of settings for input resistors and capacitors to match different MM cartridges. PRA-9X phono amplifier is a 2-stage RIAA amplifier that utilises NJR MUSES8820 audio quality op-amp to provide an accurate RIAA curve and low distortion at high amplification and performance. Line Outputs include four NuPrime’s new ultra-low distortion amplifier modules (THD=0.0004%) composed of MUSES8820 op-amp in a new amplifying circuit. It has excellent ultra-low distortion and high driving force characteristics. Features LP vinyl RIAA phono amplifier circuit, with adjustable input capacitance and impedance. Input and output fully balanced preamp. Utilizing the MUSES8820 bipolar-input dual op-amp module, PRA-9X can reproduce the presence of an orchestra as experienced in a symphony concert and the breathing sound of a player in a live music house. NuPrime’s next generation current booster circuit, providing top 0.0004% (7.5Vrms) THD performance and 114dB signal-to-noise ratio (S/N). High-performance headphone amp output. Input and output Trigger for power on/off control of multiple devices.
