We made this section a bit longer than you usually see on other web sites on purpose because we are based in China, far from you home country, so we considered it very important for you to know in detail who we are.

One sentence would sum-up Doge’s business philosophy:  « Quality first, quality always ».     We are proud to be one of the most reliable Hifi manufacturer from China


Doge was founded by a very experienced person in the Hi-Fi industry, Mister Zey LIU, ex- Jolida’s chief engineer, ex Shuguang engineer.

Although DOGE was created « only » in 2002, Mr Liu has more than 20 years of experience in High-End audio design. Indeed, Doge Hi-Fi history starts in reality in 1994 as it has some close connections with the US Maryland corporation JOLIDA Inc.


 In 1994 Jolida Inc., who had a long term business relationship with Shuguang tube factory for distributing their military vacuum tubes in U.S., was willing to develop new markets. At that time Doge’s founder Mr Liu was a Shuguang employee and was in regular in contact with Jolida Inc. Jolida asked Mr Liu if they would agree to design and manufacture a range of amplifiers for them. At the same time, they found a Chinese investor to create a Joint Venture to open a dedicated factory. This was done in 1995 in Shanghai under the name of Shenda-Jolida Ltd. and Mr Liu was hired as chief engineer.

Regarding their sound performance; the first tube amplifier designs of Mr Liu were very well received. The integrated JD302 won an award at the 1996 Las Vegas CES (Consumer Electronic Show).

From 1996 to 2002, there were some « golden years » during which Mr LIU designed a lot of ‘hot’ sales products for Jolida amongst which were the Jolida’s JD202, JD302, JD502, JD801, the CD player JD100A, the hybrid amp JD1501, the power blocks ’Music Envoy’ and the phono preamp JD9A. Many of Jolida Inc. products on the market today, although having had a few cosmetic changes and a few additional features, are still Mr LIU’s own designs.


In 2002 Mr LIU was working at the Shanghai Shenda-Jolida factory, 2000 km from his Changsha home city where both his wife and child lived. For this reason he decided to quit work at the Shenda-Jolida factory and go back to Changsha city to create his own company. He did this in a very proper way, giving Jolida much advance notice and completing all his pending projects for Jolida while at the same time setting up the Doge Factory. DOGE ELECTRONICS LTD was officially incorporated in 2003.

Doge was, and still is, a much a smaller factory than Shenda-Jolida. It is not an ambitious project  created solely for the purpose of making a great deal of money. On the contrary Doge  focuses on high quality with a limited range of product, because low quality is often associated with Chinese Hi-Fi products, including Jolida.

Mr Liu wanted to design products of higher performance and higher quality standards than Jolida. The choice to produce only a limited range of products, contrary to many Chinese brands, allows Doge to have better quality control and to make Doge one of the most reliable of Chinese brands. In addition the fact that our manager has worked for Shuguang for many years allows Doge to get first grade Shuguang tubes. Indeed, most of the current Shuguang staff are still Mr Liu’s ex-colleagues and keep very good relations with him.

We must say that history has proved that Mr Liu was really the « soul » of Jolida as since he left, Jolida stopped innovating and did not make any new products from 2003 to 2010, only some small cosmetics changes to existing products.

Now the U.S Jolida has changed its name to Black Ice Audio, has split with Chinese Jolida and started to innovate again; whereas the Chinese Jolida, which remains now the only Jolida, has seen no innovation for the past 15 years.


When he became his own boss, Mr Liu didn’t just want to make the same circuits he designed for Jolida with a different chassis. Instead, without Jolida pressure about low production cost (Jolida core marketing strategy was and is still very low prices) he really wanted to go further with research and innovation, even if this would have an influence on the product’s price, because high quality products can’t be cheap. Having a small factory with limited fixed costs helped a lot to avoid productivity pressure. In 2005 a much improved version of the JD100A was released under the name Doge 6. This is an incredible CD player with 6 tubes for analogue stage and a balanced differential stage (the first tube CD player in the world to do this). The Doge 6 is still considered to be one of the best CD Players on the market with consistently great reviews on Audiogon.

In 2011, after having reached a high ‘western standard’ quality of equipment manufacture, Mr Liu decided to give Doge a new start. While still keeping this high quality in mind, he wanted to focus more on innovation, with the development of a new range of products more orientated towards the western market and the creation of major innovations such as our patented « Precision Auto Bias» in 2011. This is a computer managed bias control unlike any others on the market. In 2013 we released an improved version of the PAB which included a Dual Class A feature. This new function is able to manage at the same time Class A and Class AB on the same amplifier by changing both voltage and anode current depending on the selected class. The Doge Prima Donna was the first amplifier to offer this new feature and more recently our flagship Doge 9 PAB.

While these innovations were being put into production, Doge introduced FLS a variable Feedback Loop Selector to enhance the matching between the amp and the speakers.


Doge is still a family size company. We have a factory of 400m2 (4,500 sq ft) in Changsha and a team of 9 people including the management. Our production is divided equally between Doge brand and OEM production for western brands who trust our high standards of quality.

We consider ourselves to be a ‘hand-craft’ factory. our first priority is to the quality of our products, not to the speed of making them. the labour is cheaper in China than in Western countries, but we don’t use this difference in cost to make higher profit margin. Instead we let our workers do their job quietly, without productivity pressure and in this way we ensure that our products have the best Quality Control among the Chinese Hi-Fi factories. In other factories it is usual for productivity to be more important than quality because these factories are run mainly by businessmen whose purpose is profit rather than the passion of creating ultimate Hi-Fi.

Although we are a super small factory compared to other Chinese actors in the tube industry, we pride ourselves that we are well known in at least 35 countries (or autonomous regions of China): Australia, Austria, Belarus, Belgium, Brazil, Canada, Colombia, Denmark, France, Germany, Hong-Kong, Hungary, Indonesia, Israel, Italy, Japan, Lithuania, Mongolia, Netherlands, New Zealand, Norway, Panama, Poland, Russia, Serbia, Singapore, Slovakia, Slovenia, South-Africa, Spain, Switzerland, Taiwain, UAE, UK, USA.

We did this without any advertising.  All our sales are done by word-of-mouth through internet forums and blogs. Our best advertising is the quality and performance of our products.
