YaqinAudio

Yaqin is one of the more prolific Chinese manufacturers of valve (tube) based audio equipment. They claim to have "engage ["sic"] in power amplifier research and production more than 10 years." [ [http://www.yaqin.cn/en/company.html Foshan Chancheng Yaqin Sound appliances factory ] ] Despite being outclassed [Transistor#Comparison_with_vacuum_tubes] by modern transistorised (solid state) equipment, some audiophiles still believe that a valve sound provides the most pleasing listening experience [Valve_sound#Explanation] [Barbour, Eric. [http://www.spectrum.ieee.org/print/1640 The Cool Sound of Tubes] in "IEEE Spectrum Online"] [Hamm, Russell O. (September 14, 1972). [http://milbert.com/articles/TvsT/tstxt.pdf "Tubes vs. Transistors: Is There An Audible Difference?"] Presented at the 43rd convention of the Audio Engineering Society, New York] [Reisch, George. [http://stereophile.com/thinkpieces/165/ Scientists vs Audiophiles 1999] in "Stereophile", March, 1999] but has until recently been typically more expensive than transistorised equipment.

Yaqin equipment is primarily designed for a 220Vac mains electricity supply voltage. In countries where up to 240Vac is normal, such as the UK, some caution should be observed. Rebadged models have been offered for sale [ [http://www.vacuumtube.com/Markhill%20Amps.htm Markhill Amplification ] ] claiming to have dealt with the power supply issues [ [http://www.destiny-audio.com/index_en.html Destiny Audio ] ] .

US and Canadian import models have been altered to operate from 110 or 120 VAC mains power.

Little reliable english language data is currently available. Often comical Engrish translations exist, for example see the nonsensical use of the terms 'gall stone' and 'gallbladder' in this sentence: 'First class-B gall stone is combined , grade is SRPP circuit before the gallbladder. The wide speed is fast frequently, the sound is nice.' [ [http://www.yaqin.cn/en/products_hf.html Foshan Chancheng Yaqin Sound appliances factory ] ]

Notes

The name 'Yaqin' is probably derived from the Chinese musical instrument 'Yazheng' but may also relate to the Arabic work 'Yaqin' meaning certainty, or that which is certain. It is also notable that the logo contains the Greek letters 'Ψ' in place of the 'Y' and 'Θ' in place of 'Q'. This has led to many confusing alternative references on the web to both 'Yaoin' and the hypercorrected 'Yaquin'.
