Added testimonial from John Bradley

Here’s another feedback today. He sent me his feedback assisting him in setting up Fidelizer Pro software.

Makes a huge difference in sound quality!

Here’s a new feedback today. He sent me his feedback after purchasing Fidelizer Pro through wire transfer as below.

Hi. Thx, got it to work. This is my “review” of your software.

Fidelizer Pro offers a bridge where sound and music merge into a believable, lively and musical experience. The sound pushes the music to a higher level where you get more emotion, more depth and more joy from the music one loves. The software is cleverly written and outthought, using sound profiles adapted to specific consumer needs and the configuration of your hifi system.

Congratulations, Keetakawee.

I’m happy to hear that he understands that I wrote Fidelizer with thoughts to bridge digital audio as close as possible to real sound experience and happy listening. 🙂
