Oppo ha 2 se – The World’s Best?

INTRODUCTION

Recently on our youtube channel, we covered what a “DAC” is. In this video, we covered three different ways DACs are used.

DISCLAIMER

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

Overall Thoughts

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.
