Audiophile Optimizer / Fidelizer

 PDF is not available and talks Windows 2012.  Red flag, a software download and says "shipping calculated on checkout" ?  

I sent them a query. 

I use Fidelizer; a free copy on one PC used for streaming and a paid version on another PC used for streaming on a 2nd system. To directly answer your question, this software does run on both my machines, each using Windows 10.

[Edit]: I now realize that the original poster may have meant to type Windows 11 and not Windows !! So, my post here does not directly answer the question as to if it runs on Windows 11.

I use the paid version of Fidelizer on my Windows 11 PRO music server. Works very well and I am happy with the results.

Also, I had positive results during the purchase process when I bought my copy of Fidelizer and have received one (free) update to the software from the developer since my purchase in 2022.

This is simply my opinion (which no one asked for...), but I feel the software adds just a touch of improvement to what I was hearing on my primary audio system (McIntosh electronics, JBL Synthesis loudspeakers, modified PC as streaming source). It was enough of an improvement that I bought the software after using the free version for months. I have no measurements or data to prove things improved; but just used my ears to make the decision to justify the use/purchase of the software.
