Here’s another feedback today. He also compared with his friend’s notebook using free version to see the immediate result.

So happy with Fidelizer Pro now!!! Sound is just amazing! Compared to friend’s notebook with Fidelizer free version and my notebook won!!! 🙂 A time ago with both Fidelizer free on our notebooks – they were almost the same sounding!!! Thank you very much for a great software!!! I’ll post info on our audiophile forum so people know and buy Pro version!!! 🙂

If you’re using free version and want better sound, upgrading to Fidelizer Pro seems to be a fine plan.
