Here’s a new feedback today. This time it’s from a careful customer who bought Fidelizer Pro, refund for further testing first and bought again.

HI , I just tried HQplayer with purist level and audioplayer option , it sounds very detailed and much better than jplay+foobar.

With HQP , Fidelizer really improve the SQ without side effect.

Glad to hear Fidelizer improves sound quality without side effect. Fine-tuning software is very important.
