Amplifier (With DAC) – Black – Brand New, Sale! Unison Research Triode 25 Int. Amplifier (With DAC) – Black – Brand New, Sale! £2300.00 Add to wishlist Watch this item Ask seller a question Description Customer Reviews Delivery Payment Returns Description Unison Research Triode 25 Integrated Amplifier (With DAC) – Black – Brand New, Sale!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.
Using a push-pull structure in this amplifier design allows for numerous benefits, including higher-output power compared to single-ended designs, improved efficiency and no static polarization of the output transformer for greater performance in the output section. However, for this to work well it is essential that all the individual amplification stages are carefully designed and constructed to prevent the formation of dangerous and compromising odd-order harmonic distortion. This is true for the two semi-output amplifiers, and even more important in the output transformer.
The Triode 25 can operate in two modes: triode and pentode. The latter is capable of delivering a maximum power output of over 45 watts per channel (6 load) with minimal harmonic distortion across the entire audio band.
The addition of a USB input modernises the Triode 25 and increases its appeal to the growing world of computer audiophiles, who use their laptop or computer as a high-quality audio source for their hi-fi. The USB input is 32-bit/384kHz and DSD 128 compliant to support the latest standards in studio quality audio.Key Features:Push-pull integrated valve amplifier32-bit, DSD-compatible USB input for streaming from a computerSwitchable Triode and Pentode modesPremium design throughoutLocally sourced materialsBased on the long-standing Triode 20 designEL34 tubes in the output stageRC2 remote with black wood finish includedPremium Cherry Wood front panel (as standard, Black finish available to special order) Customer Reviews Feedback/itemFrom Buyer Date/time ExcellentAMR Audiophile Gold Hi-Fi Fuse 20mm x 5mm (8.0A)kimtanwoo (26)ExcellentFurutech FI-06 High Performance IEC Inlet – Rhodiumkimtanwoo (26)Fast Effective purchase would gladly deal with againAllman Brothers Band – Eat A Peach Vinyl LPjedgor (463)Excellent service, fast and accurate.
