Hi DaremoS,
The inside of my Rock Chip player can be seen here ( I hope!)

I guess the soundchip is the 'Elpida' one. Of course, it doesn't have all the DSP options of the Meizu M6 - the bass is not as fat, and the equalizer is only 5 band (as far as I remember - don't have it with me right now) as opposed to the 10 Band equaliser of the M6. However, my experiences are exactly as I have written above. Maybe there are audio quality differences between Rockchip players, and I intend to try out a few over the coming months - the one I have is excellent.
I primarily use the Rockchip / M6 as movie players. next comes music, then radio.
If I get a chance, I will try and put a comparison on Youtube, and you will be able to see for yourself, the difference in video playback (albeit with the limitation of Youtube quality!)
Keep smiling ! :lol:
