The Unison Research Unico Nuovo integrates a sophisticated triode stage design with advanced biasing technology for high fidelity. Its parallel double-triode configuration enhances sonic detail and accuracy over earlier models.
At the core of the Unico Nuovo's design lies a single triode stage per-channel configuration, implemented with dual ECC83 (12AX7) valves. This parallel double-triode setup effectively reduces distortion while ensuring a smoother signal flow, contributing to improved channel separation and a more refined audio experience. The innovative ionic biasing solution allows for automatic adjustment as the valves age, maintaining optimal performance. The combination of bipolar transistors in the symmetrical current mirror stage minimizes phase displacement, further refining the audio output. Power MOSFETs configured symmetrically in the output stage provide increased efficiency and superior sound delivery, enhanced by a well-designed power supply that ensures consistent voltage supply. This highly engineered amplifier showcases a scientific approach to modern audio design, focusing on preserving the acoustic integrity of the source material.
