My final Rating: 9/10

Purchase Date: September 2012
Purchase Price: £220

In September 2012, I was extremely lucky to win a raffle prize during an audio meet. When I went to pick up my prize, I had to choose between headphones I wasn’t too keen about. Then a little brown box was pointed out to me, and I wondered what was inside. I went ahead and opened it and after seeing what was inside, I immediately claimed the prize. What laid inside the box was this little amp called the Just Audio µHA-120 (JA uHA-120). At first I didn’t know what to expect, but after plugging it in with excitement, my face lit up in joy. The company behind the amp is called Just Audio, and the name of the owner of JA is called Justin, who runs everything that relates to the amp.

The JA uHA-120 can be purchased from HiFi Headphones for £220
More in-depth information of the amp can be found on Just Audio’s website, where a full description of the amp and a guide on how to change the jumper settings can be found.
