I gotta agree with @milpai and @fuzztone about Fidelizer helping with sound quality for your PC. It's cheap and easy and if you are using Windows, that platform is not good at processing audiophile quality audio without a little bit of help. Probably the best bang for your buck to start with.
Note that Ayre that @audiom3 references has a USB driver on their site that can be (should be) downloaded (for their products) which will greatly improve audio quality for Windows. I use McIntosh DAC's and they have similar drivers that are mandatory for good USB audio quality. So, again, PC's need a bit of help, manufacturers know that and supply drivers.
I use two PC's for streaming (only) on 2 systems I have. In both PC's, I employ JCAT USB and Network cards powered by an external linear power supply, stripped down Windows 10 Pro (get rid of all the unnecessary drivers, software, etc.), reasonable Corsair power supply with zero speed fan mode, CAT8 shielded ethernet cable, etc., etc., etc. I prefer the sound of both my PC's over even my $5k CD player.
When I started this whole computer audio thing, I went from a $6 printer USB cable to a cheap name brand USB cable and finally to a very high-quality USB cable and it made a world of difference each time I upgraded. It was most noticeable in the low frequencies.
@milpai - Exceptional PC build in your profile! I bet that sounds fantastic and it looks great.
