The Unico Primo Integrated Amplifier embodies auditory precision through its advanced circuitry. Its design is rooted in acoustic integrity, allowing for a rich and true sound reproduction.
The Unico Primo Integrated Amplifier utilizes a dynamic Class A output stage with POWER MOSFET paired transistors, achieving high linearity and low distortion characteristics. The input stage is designed with A-Class A triodes, specifically employing an ECC83 (12AX7) valve to enhance the harmonic richness of audio signals, while the carefully selected components and construction methods reduce noise and interference. With a frequency response extending from 10Hz to 100kHz, the amplifier ensures faithful reproduction across the audible spectrum, affording a signal-to-noise ratio (SNR) of 90dB and total harmonic distortion (THD) of 0.15% at 10W, highlighting its capacity for clarity and fidelity. The inclusion of negative feedback and a damping factor greater than 50 aids in managing speaker control, offering superior transient response and a cohesive soundstage.
