The sound is so satisfying, wide and deep that I feel like I can stand up and walk to each instrument. I decide to get the Pro version, and now I am totally hooked on this app. Initial impression was very positive (immediate improvement in bass definition and darker background, more space as well.). Then I came across Fidelizer, and tried a demo version. Every single bit contributed toward a more natural presentation. helps with linearity at high frequencies )Īll 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. I feed audio signal straight of the DAC I/V resistors, and into the amplifier (very high input impedance as well. Then I built a balanced, single-ended class A amplifier, DC-coupled (two gain stages only). The sound gained details, space, bass definition, the background was darker. A few years back I upgraded my XMOS sound card (USB to i2s) crystals from NDK SD to SDA's with a noticeable difference.

for pretty short money, you'll get much blacker background, more texture in instruments, and better soundstaging. I can't say which one "sounds better" - they're a good partnership. once you've run fidelizer pro in the mode you want (like a.o.) it will automatically launch on start-up and the settings will be used until you uninstall them. fidelizer pro's optimizations effect normal computer operations to a lesser extent and fidelizer can be uninstalled. you can disable the optimizations that it does, but it's always there.įidelizer concentrates on optimizing the audio processes within windows - it's very focused. works best when you can start the computer, operate your player software and do nothing else. if you go with the extreme settings (which sounds best), you can disable services that will make navigation difficult.

the idea is to minimize the work being done by the operating system, reducing noise. concentrates on manipulating and shutting down parts of the operating system.
