As a contra-example to what I mentioned myself, there is a label from which you can download files online and do comparisons and for some of their 'DSD' files, they actually sourced the material from DXD - that's very high-rate PCM. Any processing (if necessary) would be done at that very high-rate (something like 352.8kHz:

Therefore, so as to minimise the SQ losses (not eliminate them), you could consider that, e.g. in a DAW, process as DXD.
However, whenever high quality needs to preserved, people like Cookie Marenco (Blue Coast Records) and in the near future, Paul McGowan (for PS Audio's new studio and label) have opted for mixing DSD in the analogue domain.
A few years ago, I did the tests in my own setup: up to DSD256, Audirvana on macOS -> iFi iDSD Nano, with a DIY USB isolator and DIY very low loise Linear Regulated PSU injected to power the DAC -> SET Tube Amp -> Totem Mites on dedicated Audio Power Lines.
From those tests, I abhor any conversion of DSD to PCM and back to DSD. A single upconversion of PCM to DSD was acceptable though.
Note here that my DAC was a DAC with a native DSD mode.
DSD is best left untouched, or converted to higher rate DSD if that's your sweet spot, or if any processing is needed, best processed in the analogue domain. It really is analogue storable in digital format: at the output on a pin, the analogue musical content is already there as it can be listened to through a simple RC filter into the rest of an analogue chain.

2L label?
It's better to upsample all PCM files to 352.8kHz before the EQ, I know severa SRC what's the best or with best SQ?
Guys Thanks for help

I wouldn't say 'it's better'. It's more correct to say, it's better than EQing low-rate PCM after DSD->PCM. And that's the case where you've decided to do DSD - > PCM, itself a compromise.
A way to do DSP on DSD is converting the DSD to multibit, e.g. 64-bit stream preserving the DSD rate, then low-pass filtering get rid of the ultrasonic noise, processing in multibit domain, then re-converting to single bit.
That multibit isn't PCM, it is a form of DSD Wide.
Apparently, Roon allows processing like that.
Yes multibit can be EQed or other DSP.
If you don't want to convert DSD files you are going to have to do analog EQ, as YashN mentions. It could be active or passive. OK for some things, but it's going to be difficult to do any fancy DRC with analog filters.

How to do it?
How to do it?
Is it just for listening to a headphone, so it doesn't matter if you convert and save the files, or do the EQit while you play the music (inline)?
In that case HQPlayer is what you want.
All other options are IMHO just inadequate, but it is more costly. Versions are for Linux, Windows, Mac, local, remote etc. Correction can be done with convolution or EQ lingo (easy)

I tried but I see too much complicated & interface doesn't helps, do you have links to tutorials or guides exactly for what I want to use it, so PEQ DSD? Do you know if once EQed can be saved the files? BTW 30 minutes at time without license key it's few time to know if can do that I need?
TIA

HQ Player on a main PC with small SBC via Ethernet using Jussi's HQ Player Client is one of the best things you can do for your DSD setup (and realtime PCM upconversion).
YashN do you use HQPlayer? Cost 241€ , downloaded the demo trial and can't set up the Library to listen the music with the HQPlayer 4 Desktop? It seems with a lot of possibilities but these same amount the possibilities does the setup a lot of more complicated
I use Audirvana, but I evaluated HQ Player for quite a while, including using my MacBook Pro as NAA (Network Attached Audio) running the client.
Best is to download the right version and see how it works. Yes it can do the things you want and more, the manual is in the installation folder etc.
It does have a steep learning curve, but I've used it for around 10 years and can't think of anything better sq and capability wise.
Best thread for questions is at Audiophilestyle.com:

30 minutes: after that you restart the software to have 30 minutes again.
The only version that let's you save files is the studio/pro version, but it's around €3000.-
You just have to ask yourself if it is smart to have the original version and the eq'd ones on your drive. Much easier to change the eq and hit "play" imho, but similar case can be made for saving them. Matter of taste maybe, more important is if your pc can handle the parameters HQPlayer offers you and you want to use.
Goodluck!
