Recently on our youtube channel, we covered what a “DAC” is. In this video, we covered three different ways DACs are used. One way was to improve your sound quality with a portable dac/amp such as this one. The oppo ha 2 se and I go way back when I first started my portable audiophile journey. This was my dream device and when I first got it, I jumped with excitement. And here is why…

Oppo ha 2 se was bought by me for personal. As usual my review will contain no bias
THE BUILD QUALITY
To simply put it, Oppo ha 2 se is the most well-built device I have seen. It is full aluminum with every detail made to perfection.
The scrolling button is gorgeous and every button is made so that when you press them, you just press them again because it feels so great. For the price, you really can’t find a more premium build.
It is also thin enough for REAL portable use.

Oppo ha 2 se adds in more body and separation while maintaining the absolute cleanness a real dac should bring
With the bass boost, the oppo ha 2 se adds in a little more fun to the lower frequencies. I have yet to experience a more tasteful mouthwatering or ear-watering? bass boost
This device was a pleasant experience not just for this review but on my own journey to reaching my “end game.” Although I would not call this the end game for myself, it was real damn close.
