My thoughts and impressions on the Hiby RS6 after owning it for some time now:
Sound Impressions:
After having the iBasso DX300 + Amp11mk2 for over 8 months, I knew something was missing from my music that I couldn't pinpoint. After some discussion among friends one of them suggested I try the Hiby RS6 and I am so glad I did! The RS6 provided a sense of warmth and excitement in my music that I was missing from the DX300. The DX300 also leans brights which doesn't play well with bright-leaning transducers that I own, like the Symphonium Audio Helios, so the easier treble listening + better dynamics + warmth is an easy win for me for the RS6 over the DX300.
Usability and Features:
-The Darwin software is great and a tinkerer's dream, I can really see endless possibilities from the DSP engine and I hope it'll be supported in the future!
-The poweramp equalizer app does work with the RS6 which didn't on the DX300 so that means you can easily apply PEQ if you so choose to, I don't know if the Darwin function will work though.
-Having the volume wheel protected and not protruding means you can easily put this in your pocket and not have to worry about accidentally turning off the DX300 (which has happened to me in many occasions)
-The idle auto-shutdown feature is a great idea and I'm surprised more DAP manufacturers don't have this.
-This is a fast DAP! Very snappy like the DX300 and fits in the palm of your hand
Misc Thoughts:
I bought this Hiby RS6 from MusicTeck. Communicating with Andrew was an easy and delightful experience. I had wanted to change my shipping after I made my order on MusicTeck and Andrew was very quick on helping me get sorted. For those US based, I'd recommend getting from MusicTeck because you'll get quick warranty support if something were to happen and shipping won't cost an arm and a leg.
Conclusion:
I've sold my DX300 and am happy to call the RS6 my endgame DAP (for now I guess).
