Here’s a new feedback today. This is probably the first feedback I published from free version.

This is a report of our first experience with Fidelizer.

I had heard of a few optimizer programs designed to improve computer audio sound, but I was sceptical. After looking around on the web I found an interesting product called Fidelizer. I decided to give it a try for several reasons; it had good reviews, the creator was very active in support of his product, and there was a free version.

It sat on my Windows 10 computer while I attended to other things. I finally got to install it and the sound quality into my Devialet 200 DAC/amp was seemed improved when I was using Devialet’s Air app to stream via Ethernet. However this happy state of affairs did not last long enough to make any conclusions about Fidelizer. The Air program and Windows 10 stopped working together after a Win 10 update and I could get no music to play via Air over Ethernet. Troubles with Air are common among Devialet owners. So I grudgingly went to the inferior sounding USB input. Quite a drop in sound quality in my setup.

Ok, let’s try that Fidelizer app and see what it does with a USB connection. So my audiophile wife, yes such creatures do exist, and I got comfortable in our Audio room for what we assumed would be a protracted listening session to notice any differences with Fidelizer. Kuhn Keetakawee, the creator of Fidelizer, had suggested I use the maximum setting of Fidelizer free which is called Purist. Yes, I got a personal email from the creator of Fidelizer in using the free version. That is rare! Ok all set, and we listened to three familiar tracks without Fidelizer. Nice, but not as good as over Ethernet with the infuriating Air application. Install Fidelizer at Purist level and fire up Girl Combo’s a’cappella powerful rendition of How Great Thou Art. Maybe ten seconds into the tract my wife and I are staring at each other in joyous disbelief. My wife says, what happened it sounds great. Yes it was a very big jump in sound quality in our system. It brought the USB connection close to Ethernet connection with the oh so infuriating Air app. I explained to my wife that this was the free version and there were two more powerful versions with promised improvement at each step. I also mentioned Kuhn Keetakawee’s optimally Fidelized music server.

We came to following conclusions regarding Fidelizer, we ordered the maximally Fidelized Nimitra music server, and my wife renamed the product for us as the Fabulizer.

I guess most people probably already upgraded before providing feedback and he also purchased Nimitra music server.
