Here’s another feedback today. I received his feedback after sending Pro version few days ago.

Hi, finally is worth the effort, Fidelizer is rewarding, easy to use and also easy to notice the upgrade, when purist is awesome!.
Also I am done with Foobar, I have nothing against their app as a remote!
Only is need now, to install Asio drivers for video player, but this is for tomorrow.
I suppose purist mode, can’t play video, I will see soon.
I thought Fidelizer were more difficult to use, but I was wrong.
Cheers,

Fidelizer is very simple software. You can simply press a single button to improve sound quality. 🙂
