Fidelizer - Any experience?

UPDATE: I purchased the PRO version after a couple weeks of trying out the free version of Fidelizer. Other than upgrading speakers, this software has provided the most sonic benefits I have heard in my modest system. Improved dynamics, soundstage, transients, and vocals. I was listening to “Crosseyed Mary” from Aqualung, and Ian Anderson’s voice had such anger, vitriol, and passion in it that I had never heard before. I am a believer.
