I also like Fideliser in the Pro version. There is also a superb set of software at considerably more cost and it comes from Laufer technik and it was designed by Mark Porzilli of the Memory Player fame. You can buy bits of it at a time to spread the cost but each part paves the way to a glorious whole.
Fidelizer-Audio for Windows pc
Years ago, I tried Fidelizer-Audio for streaming Tidal. At that time, it was a nice improvement – on
the scale of a good tweak. Now, my
system is considerably more resolving via quality cabling, power supplies and power conditioning.
With Fidelizer Pro currently running on a dedicated Windows laptop, the improvement in SQ is quite significant. Clean and dynamic! Fidelizer turns off computer processes that make noise, not music. If you’re using a Windows pc for streaming - or playing back music files, I highly recommend auditioning the free trial version of Fidelizer. It’s almost as good as the Pro version.
