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."[1] Despite having several disadvantages[2] compared to modern transistorised (solid state) equipment, a valve sound is preferred by some commentators as having the most pleasing listening experience[3][4][5][6] but has until recently been typically more expensive than transistorised equipment.[7]
Yaqin equipment is primarily designed for a 220Vac mains electricity supply voltage. In countries with 230Vac such as the UK, some caution should be observed[citation needed]. Rebadged models have been offered for sale[8] claiming to have dealt with the power supply issues[9].
US and Canadian import models have been altered to operate from 110-120 Vac mains power.
Little reliable English-language data is available as of 2010[update]. Often comical Engrish translations exist, for example 'First class-B gall stone is combined , grade is SRPP circuit before the gallbladder. The wide speed is fast frequently, the sound is nice.' [10]

[edit] Notes
The name 'Yaqin' is probably derived from the Chinese musical instrument Yazheng but may also relate to the Arabic word Yaqin meaning certainty, or that which is certain, although there is no real good reason to think that a Chinese company would use an Arabic word as its title. Especially since the 'Ya' character (雅) means 'elegant' or 'proper'. The 'qin' character (琴) in could easily be a family name. It is also notable[says who?] 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'.
