Unison Research Triode 25 DAC Valve Amplifier

The Triode 25 DAC is an exceptionally high-quality audiophile amplifier, designed, engineered and constructed by Italian valve experts; Unison Research. The Triode 25 draws inspiration from the company's long-standing and well regarded Triode 20 amplifier and was released as part of the company's 25th year anniversary. It also features a USB DSD DAC within, in order to give your digitally stored music files the sound of warmth and clarity that one would expect from any product designed by Unison Research. 

The Triode 25 uses a push-pull design, that makes use of EL34 tubes within the output stage. The push-pull circuit sees the inclusion of a final stage with two power tubes seated within, intended to amplify the audio signal. This is then followed by a symmetrical output transformer stage, designed to reconstruct the signal into a high-quality linear wave. 

Using this method of amplification allows for a number of benefits to the overall sound that the amplifier is capable of offering, as a high-output power is achievable, as well as improved efficiency and the eradication of static polarization, often found in the output transformer. 

The Triode 25 can operate in one of two modes, these are 'triode' and 'pentode'. Pentode mode is capable of outputting the maximum amount of power of over 45 watts per channel (6-ohm load), with an absolute minimum of harmonic distortion experiences across the entirety of the audio band. 

The USB input is 32bit/384 kHz and DSD 128 compliant, meaning that this amplifier is capable of supporting and enhancing the latest standards in studio quality audio.
