Thivanlabs 811-572

The 811/572 single-ended Headphone & Speaker amplifier launched by ThivanLabs in late 2017 was the world's first 811 tube headphone amplifier. The 811/572 single-ended Headphone & Speaker amplifier marks the return of Thivanlabs into the headphone amplifier market after many years of research to improve and enhance high-end headphones aimed at high-class customers. This amplifier model can be used with high-end headphones and loudspeakers to enjoy music of high fidelity at home. Such flexibility from the 811 Headphone & Speaker amplifier allows its users to be completely submerged in the world of high quality music without causing any disturbance to a third party, and yet, let them rock the room when it comes to sharing their music passion with family and friends. The latest 2019 version of the Headphone & Speaker amplifier has been refined to enhance the users music experience by the interchangeable use of both 811 and 572 tubes. ThivanLabs is a pioneer in using these two types of tubes for its commercial designs of light tube amplifiers. Thivan's single-ended 811 amplifiers have been technically developed for many years, and so far have been trusted by a number of domestic and international users. These products are currently exported to European markets and are sold by ThivanLab's official international distribution agents. An elite feature of the 2019 Headphone & Speaker amplifier is the optional use of a 572 tube for the power stage. This product line hence comes in two official versions the 811 Single-ended and the 572 Single-ended. After several months of technical tests and design optimization on this amplifier with 572 tubes, the company has finalized these two versions, raising music reproduction to a new level live-like performances of authentic, smooth, detailed, and inspiring sound quality. The 811/572 Headphone & Speaker version also still inherits its predecessors advantage of being flexibly connected to two headphones simultaneously without any interruptions to sound transmission and quality. Aimed at high-end headphone lovers, ThivanLabs's Headphone & Speaker amplifiers have been tested and launched as products for high quality sound, namely: - Denon AH-D5000 / 7000/7100/7200 - Sennheiser HD650 / 800 / 800s - Beyerdynamic (full collection of headphones, some typical headphones such as T5p / DT 880 ) - Grado GS1000 - Sony MDR-Z1R - Final Audio Design's Pandora Hope
