Unison Research Sinfonia Mahogany Valve Stereo Integrated Amplifier

Unison Research Sinfonia Mahogany Valve Stereo Integrated Amplifier

Thanks to Unison Research's extensive knowledge of output transformer production, the Sinfonia has been designed with a power stage that is made up of two KT88 valves per-channel in single-ended parallel ultra-linear configuration, in which the KT88 (beam power tetrodes) operate, with good approximation, like an ideal triode. This configuration provides very good results in terms of sound quality, however the natural drawbacks of valves (namely the non-uniform decline in performance over time due to drift) need to be addressed. So, after much testing, Unison Research developed an an original circuit design which, through the control of the KT88 bias, ensures a real-time compensation of the parameters affected by drift. This solution guarantees the best sound quality even after many years, and also contributes to a slight reduction in the time it normally takes for the tubes to warm up after switching on and reach the optimal temperature.

Unison Research Triode 25 Cherry Valve Stereo Integrated Amplifier

Unison Research Triode 25 Cherry Valve Stereo Integrated Amplifier

The Triode 25 was born out of the huge success of the long-standing Triode 20 amplifier, and released as part of the 25th anniversary celebrations of Unison Research's formation. It's been developed over an extended period to ensure it is a worthy successor to the Triode 20's name. Like its predecessor, the Triode 25 is a push-pull amplifier that utilizes EL34 tubes in the output stage. The push-pull circuit includes a final stage with two power tubes intended for the amplification of the audio signal, and is then followed by a symmetrical output transformer stage that reconstructs the signal into a high-quality linear wave.

Unison Research SH Headphone DAC Cherry Valve Amplifier

Unison Research SH Headphone DAC Cherry Valve Amplifier

The SH began with the same basic remit as the coveted Simply Italy integrated amplifier; to produce a world-class sound from a specialised device using the best technology available. The result was a fairly simple, linear circuit that produces an output voltage which is more than capable of driving a wide range of headphones, while keeping distortion low throughout the frequency range. This allows the SH to deliver a consistent, coherent sound character when in use.
