Here’s a new feedback today. I received his feedback only few hours after delivering Fidelizer Pro yesterday.

Thank you!

Yes, I do believe that when Fidelizer is engaged there is a greater sense of spaciousness, more dimension and air. Very similar to what I hear as jitter levels decrease.

I have gone to great effort to minimize the transfer of noise down the USB bus,

but different software players sound different, and the best sounding player I have tried so far didn’t offer enough features, so I went back to Jriver, which sounded just a tick more flat to me.

Now when using Jriver, there again is greater dimension.
Trying to understand WHY software optimizations would make such a difference, all I can reasonably come up with in my mind, is, the less processes that run, the less hardware that need be engaged, which leads to less noise being created and sent down the USB bus and the ground plane, and greater signal integrity, which is also very important, as it means less processes need be active in the USB receiving chip, which, again means less noise pollution.

There are those that disagree, but my experience is jitter matters, and in a bigtime way, and even small changes in timing make a very real audible difference. Every little thing that can be done to improve signal integrity and lower noise, therefore improve clock performance, is important and adds up!

Thank you!!

There’s a lot of computer audio issues today and I’m glad Fidelizer can make things simpler for everyone. 🙂
