This is a JUNGSON DA 300-IA integrated amp 300 w/ch CLASS A/B
(look is similar to JUNGSON JA99-D 100w/ch)

Selling because I'm back to tubes forever.
This integrated amp is a surprise, and a very pleasant one.

* Please no lowballers. Lower offers will be politely ignored.

** Note about this link - this is a very similar model except rated 100W per channel instead of 300W per channel:


Time to downgrade, different setup in a smaller room.

1st owner, I am regretfully selling my wonderful JUNGSON DA 300-IA integrated amp 300 WPC CLASS A/B (with very low hours, it was part of a secondary hifi system).

Truly in MINT condition! No issues whatsoever! Working perfect!

I'm very picky when it comes to item description: it has a very tiny scratch on the corner of the faceplate, I don't see it unless I get very close.

This amp has a warm tubish-like sound and has TREMENDOUS POWER!

Excellent for power hungry high-end speakers.
Convenient line out (L+R) for hooking a subwoofer.
Premium quality speaker binders allowing normal or Bi-wiring (Total: 4 pairs)

Built with Premium quality parts all the way.

Jungson is a premier Chinese manufacturer. For years, They’ve privately manufactured for many top Western brands.

This LUXURY MONSTER INTEGRATED AMP is built like a TANK, it was purchased from GRANT FIDELITY (Calgary) in 2015. This unit was specially made them for and tested here in Canada, so you won’t find much info on the web except for this quite similar Class A model JA99-D:

*Note about this link - this is a very similar model except rated 100W per channel instead of 300W per channel.

Who is Jungson Audio?

Posted on April 14, 2011 by admin: http://grantfidelity.com/factories/?p=73

Jungson Audio (on many websites, it is referred as JungSon) is one of China’s premier Hi-Fi manufacturers. The word ‘Jung-Son’ is from the Chinese pronunciation of the company’s name – Zhong Shen, meaning ‘Spirit of Chinese Ancient Bell‘. Bells were used as musical instrument in China since 3500 years ago for ceremony and important events.

Jungson Audio is China’s premier high fidelity audio manufacturer and is best known for its Class A and A-B designs.

Jungson Audio was started by two audiophiles in 1993 in a small town in southern China, Taishan, where 90% of the families there have ties with North America through their ancestors who went to North America to build the rail roads starting from 1860s. The two founders, one were then teaching electronics at a college, the other one was his student, started the business out of their passion to audio and music. Their start-up stage is like many stories we heard in the western world – self financing, limited space and no brand recognition. They took their first product – 70 lbs solid state amplifier on the train and went to Guangzhou (which is China’s Hi-Fi capital) to look for interested customers. Just while they were exhausted by lugging such a heavy amp without a vehicle (in 1990s, majority of China is still on two wheels – bicycle) from shop to shop but no one paid attention to them, and they were about to return home, a foresighted vendor welcomed them into the shop for a demonstration. Not to mention that the store owner is so impressed by the product and decided to carry the product. From then on, Jungson started to prosper. The real take-off of Jungson happened when China’s national radio station took on one of their amps for studio monitoring in the 90s. Since then, Jungson has been continuously bringing out excellent products, from mighty power 200W monoblocks to smaller integrated amps.

Jungson Audio is also one of the handful manfuacturers in the world who makes full line of audio components, from wall out to the ears. Today, as we speak, Jungson is building their now premise in Taishan with 6 buildings on 15 acres of land. The down-to-earth owners told me: “Many audio companies choose to located in major cities but we decide to stay in Taishan. We like where we started and we would like to stay focused on making great audio, rather than be enticed by money and greed.” I have personally visited Jungson twice in the past two years – they have a great team of designers, all young in their 20s and 30s, except the owners are in their 40s, plus a dedicated production team who are mostly from Taishan.
