Unison Research Triode 25 Black Edition – a new tube-based integrated amplifier

26.10.2022 11:00 | ~1 minute read

The Italian company Unison Research has presented a special version of one of the company's most successful products – the Unison Research Triode 25 integrated amp. This version features an exclusive bronze finish, glossy black front panel and a body made of dark anodized metal.

Unison Research Triode 25 Black Edition – a new tube-based integrated amplifier

According to the manufacturer, the Unison Research Triode 25 Black Edition has an optimized amplifier circuit - both in the signal path and in the power supply. The topology of the ground tracks and the physical separation of the channels were carried out with particular care. As far as possible, the audio signal is transmitted via shielded high-quality cables. The amplifier section has an adjustable bias voltage, and the feedback can be adjusted in two positions.

The Unison Research Triode 25 Black Edition integrated amplifier supports two output stage modes - triode and pentode. In triode mode, the amplifier raises a power of up to 30 Wt per channel, and in pentode mode - 50 Wt. The pre-amplification section uses two ECC83 Gold Lion dual triodes and one ECC82 Gold Lion. The output stages uses four KT77 Gold Lion tubes (a pair per channel), operating in push-pull mode. The Unison Research Triode 25 Black Edition integrated amplifier should soon go on sale in Europe at a recommended retail price of 4,299 euros.
