Hi Keetakawee,

Fidelizer Pro works great for me. In the first place, I do not want to fiddle with computer settings and this product is easy to use. Tested it in my office (free version) and in my main system and the improvement in SQ was obvious in both. I even tested it with a coworker, (who is not an “audiophile”) and he was able to spot the difference in no time. Not easy to explain, but for him (and for me) music sounded less “confused” and better defined. I heard improved separation between instruments, a blacker background, and deeper bass rendition.

Kind regards,
Juan
