Here’s another feedback today. He shared his feedback after using Fidelizer Pro in online community as below.

I have a very revealing system. A few years back I upgraded my XMOS sound card (USB to i2s) crystals from NDK SD to SDA’s with a noticeable difference. The sound gained details, space, bass definition, the background was darker.

Then I built a balanced, single-ended class A amplifier, DC-coupled (two gain stages only). The overall sound was impressive. I feed audio signal straight of the DAC I/V resistors, and into the amplifier (very high input impedance as well… helps with linearity at high frequencies:))

All along I was working on minimising the switching artifacts coming from the laptop (used as a JRiver streamer), so I was under-clocking the CPU, killing the unnecessary services, playing with the power supply. Every single bit contributed toward a more natural presentation.

Then I came across Fidelizer, and tried a demo version. Initial impression was very positive (immediate improvement in bass definition and darker background, more space as well…). I decide to get the Pro version, and now I am totally hooked on this app. The sound is so satisfying, wide and deep that I feel like I can stand up and walk to each instrument. Stunning.

I will now install Win Server 2016 from the scratch, and then install only the bare minimum (JRiver and the necessary drivers), and then treat it with Fidelizer Pro.

The audio player without network connections profile is infinitely better than any other profile. Option to choose filters is also nice.

The best thing is that the Fidelizer opens the JRiver on bootup and then starts playing the music. Fantastic!

I’m happy to hear that Fidelizer can help feeling the real sound better and happy listening. 🙂
