Conclusion

The HiBy R8 II is an impressive high-end Android digital audio player that excels in build quality, sound performance, and feature set. It is well-suited for audiophiles who demand the best in portable audio. However, its high price, occasional software issues, and potential learning curve may be drawbacks for some users. Ultimately, the R8 II is a strong contender in the premium DAP market, but prospective buyers should carefully consider their specific needs and preferences before making a purchase.

I have been using this sweet device for a month & let me tell you, it is eye-opening. The learning curve has been rather steep for me since this this is my first real DAC. This is like learning to drive for the first time but you only have a V12 Ferrari. This flagship has 2 types of Amplifiers, A & AB. I have left it on A because it sounds most natural. This device is heavy, almost twice as heavy as a high end mobile, so it is not something ultra-portable. The form factor of this is like a big mobile & twice as thick. What is amazing is that for the features & quality it has, should not be possible in such a form factor. It should have been the size of a big CD player of old, but it is tiny for its features. That tells me technology has come a LOOONG way for the audiophile from the days of Vinyl & tape, then CD, now DAC. I play it via computers, Bluetooth receivers & standalone through Blessing 3 IEM. The journey of the modern audiophile has begun, for me. I still have CD & Vinyl & tapes of old & new artists. The Hiby R8 II adds yet another dimension to this.
