After installing Fidelizer Pro on my system, I was pleasantly surprised. SQ has improved and most important, I could play now ultra/700Hz/0.01sec with no interruption. Before installing it, there was no way to achieve that without interruption. 10/11sec before the end of each song it just stops. I don’t really know what has happened (miracle maybe) but now I can fully enjoy the ultimate settings without any interruption, no matter what format is playing (DSD256 or hires or even mp3). Thank you Keetakawee!
