The 811\/572 single-ended Headphone \u0026amp; 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 \u0026amp; 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 \u0026amp; 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 \u0026amp; 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 \u0026amp; 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 \u0026amp; 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\u003c\/p\u003e\n\n\u003cp\u003eNumber of amp blocks 1 Inputs 1 XLR ; 2 RCA Speakers 4, 6, 8, 16 Ohms Headphone 4-pin XLR and 1\/4 (6.3mm) stereo headphone outputs Vacuum tube complement  Output tubes: 811 x 2 Pre \u0026amp; driver tubes: 1 x 12AU7 ; 1 x 6SN7 ; 2 x 6V6 Output Power (per channel) 20W peak (CLASS A 10W RMS) Frequency response 10Hz - 30kHz (-3dB) Input Sensitivity 800mV Input Impedance 100kOhms Power Requirements 230V (it is possible to set 100 \/ 117 \/ 240V \/ 50-60Hz by different markets) Power Consumption 170W Dimensions (W x D x H) 45 x 40 x 29 (cm) Weight 31kgs Phono MM\/MC No Remote control No\u003c\/p\u003e","brand":"Thivanlabs","offers":[{"title":"Default Title","offer_id":59370710466905,"sku":"2278","price":2800.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1066\/5721\/8905\/files\/thivanlabs-811-572-1.jpg?v=1789118968","url":"https:\/\/wenwaudio.com\/products\/thivanlabs-811-572","provider":"W\u0026WAudio","version":"1.0","type":"link"}
