Here’s a new feedback today. He’s using Fidelizer Pro on Roon bridge machine as networked audio renderer device.

Hi,
My congratulation for your program.
It works fine and the improvements are easily audible: mostly I have found a better bass articulation, more overall transparency, and a better depth of image.
Best regards,

Better bass articulation, improved transparency and imaging? You normally get them from over $1k worth upgrading. 🙂
