DAC suggestion for PC

You guys are funny... I have had many a DAC hooked up to my PC and they ALL made substantial differences.  So PCs are not limited just like many claim an automobile is so limited and no human can tell the difference between DSD and an MP3.  Such rubbish being spread about...

I currently have an Ayre Codex and a PS Audio Steller DAC/Pre.  I've had Schitt Modi MB and a Topping D90SE and those both sucked in comparison.  I want to try a Benchmark DAC3 HGC eventually.  Heck, I had some pretty crappy speakers from Logitech at first.  Then went to Audio Engine, Focal and now a pair of Ascend Acoustics Sierra 2SEs.  It all made a difference.  I master my vinyl rips on my PC, which is why I care about the SQ so much. 

Yeah, the streamer will be last purchase. Order will be 1. Speakers 2. amp 3. Replace DAC with a streamer/dac 

For Speakers, Im not sure yet, Im looking at the used market for now. I found some Sonus Faber Toy bookshelves that might be nice. Always wanted to try Sonus Faber. If not, I can wait to see if I can find some Dynaudio Emit10. 

@skads_187 ,

If you have a purpose built PC meant only for streaming, then it should be fine. I am using a PC that is passive cooled and it is couple of huge steps over the dedicated laptop I was using earlier. Please see my system page for the build I did.

I agree that Fidelizer will make a very noticeable difference. What is your playback software? You mentioned Tidal. But unfortunately they do not have a control software, to control the playback on the PC. You can use Remote Desktop to control playback of Tidal directly from the PC though, if this PC is on the audio stand away from where you sit.

For a PC I would keep it simple, compact and inexpensive. So consider a Schitt Modi.

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.
