The Unison Research Simply Italy Black Edition is an integrated Class A valve amplifier that delivers comprehensive sound transparency through innovative engineering. Its electronic polarization ensures the stability and longevity of the power valves, achieving consistent sonic performance.
The Unison Research Simply Italy Black Edition utilizes an innovative electronic polarization system, which maintains a stable operating point for the KT77 power valves, enhancing both their longevity and performance. This Class A amplifier operates in an ultralinear configuration, optimizing linearity and reducing distortion across its operational bandwidth of 15 Hz to 50 kHz. The redesign of the output transformer to a refined 5-section design significantly contributes to improved sound quality, supporting the frequency response and dynamic range. Additionally, the amplifier's circuitry incorporates advanced input selection using micro relays, which minimizes signal degradation and enhances the integrity of the signal path. With high-quality components like ECC82 Gold Lion signal valves and a dedicated DAC3 for digital inputs, this amplifier is engineered to deliver a rich, detailed audio experience while maintaining the acoustic truth of the original sound.
Key Features
- Electronic Bias Adjustment: This feature maintains optimal operating conditions for the KT77 valves, eliminating fluctuations that may lead to tonal instability over time.
- Unfiltered SUB Output: The dedicated subwoofer output ensures that the tonal character of the amplifier is preserved when driving an active subwoofer, allowing for an integrated listening experience.
- Advanced Input Selection Circuit: Utilizing micro relays combined with Return GND technology reduces crosstalk and provides superior channel separation, ensuring that each input retains the purest signal path.
- Updated DAC3: With capabilities for PCM up to 384 kHz and DSD up to 256x, the DAC3 expands connectivity and ensures high-resolution digital audio fidelity.
- Redesigned Output Transformer: The 5-section output transformer enhances frequency response and dynamic range, allowing for a more immersive listening experience.
