but just for desktop, output data only, shouldn't be a problem, right?

TOPPING HS02 coming

And don't forget about the delay issue of opticalYou might not want to hear this - or might not even believe it. But 24/96 PCM is way more than needed to transfer ALL the audible information in your hires/DSD files, without any audible artefacts. In fact so is 24/48. Hell - I'd be prepared to bet that you'd not be able to tell the difference even with 16/44.1 under properly controlled blind listening.
Unlike (at least currently) your USB connection which is adding a ton of noise.

The printed one is 49, the aluminum case is 69.It is. It includes about $30 of cable and adapters
EDIT : Except it is showing as $69 for me.
Ah - that explains it. Thanks.

It depends I guess.If you have the data at hand yes.
If is generically designed to use all the potential 500mA a USB is suppose to give,I don't know.
You can always try it of course,if you're unlucky you'll get little pops,clicks and maybe some like-static sound,trouble with higher sample rates,etc
Use short certified cables with it is another good idea,long 3-5 meter ones will make things worst.
How are you powering the RME? From the isolator (probably not with the current limit of that device).
Just as a test, why not try toslink. That will tell you if the noise is getting through the isolator, or perhaps through another path (eg the ground connection of the RME)

A box from Intona will most likely do better. Not a dongle and not cheap though.
The absolute cheapest solution for full isolation would be to use toslink.
RME is powered by the ifi Power elite, and same outlet with the active monitors. I tried to avoid the ground loop, I tried with different outlet and the noise is worse. Sure I know the optical will fix it 100%, but I want to fix the usb signal.

This, unfortunately, is not all that certain. I myself have experienced noise issues that optical did not solve. Optical noise was still the same as USB. Like you, I also bought the HS02 that reduced the noise so my subwoofers could finally go to sleep, but the speakers' noise is still not eliminated completely. I am now eager to change my amplifier to a balanced one, which in theory can be an improvement in noise reduction.

something else worth thinking about - try powering the RME from its stock PSU. The stock PSU is not earthed where your IFI one is.
And have you tried optical. If you try it - just as s test - it might show that the noise (or some of it) is coming from somewhere other than the USB connection.
Also try (with the isolator in use) running a long USB cable and as short as possible RCA Cables. If the distance between speakers forces use of long RCA Cables, try (again, just as a test) bringing one speaker next to the other and using short (less than 1ft) RCA.
If you are using an optical connection - that is not bringing any noise. If you still get noise then it is coming in somewhere else.
I tried optical with same setup, no noise. And the noise can be hear only when my GPU running while gaming. On idle, it's dead silent

So far you did not say clearly what you got. The Topping? Or the JDS? No one here tried this one so far, and it also wasn't measured. I don't know what DC/DC converter they use, and how much it affects the coupling capacity. I measured other TI ISOUSB211 devices and they worked perfectly.
I pointed you to my other posts on such devices, and you said you did not find them. They are there and easy to find. We discussed for example this one:
That one got bought and measured by me and works perfectly as well. 37 pF coupling capacity.

So that proves ground noise coming from the PC, and your new isolator not doing a good enough job to isolate it.
This suggests that changing the RME PSU won't make any difference - though if it were me, I'd still try it as an easy test to make. Ground loop current paths are often counter intuitive.
And minimising RCA cable length is also worth investigating.
Having said that - and I know it goes against "what you want" - TOSLink is by far your best solution. And regardless about what you think regarding your high res files, it won't make any audible impact. I'm not sure what you meant by "the delay issue of optical" - there is nothing inherent in Toslink to cause a delay. For example, i've just checked my toslink connected turntable, and any difference in time between the stylus contacting the lead in, and the needle drop sound is imperceptible.
I'm ignorant on the subject so I ask: this one listed on Amazon is better but if I have a Mac and a DAC with USB-C with this, unlike the Topping, will I have to use adapters on both sides of the device?
Hello everyone
I don't know if this will help
one of you.
I had breaks in my recordings
with the HS02 that I put in front of an E1DA ADC iso B
so double isolation.
I wanted to measure a floating voltage in differential
and wanted to guarantee the isolation voltage, the E1DA
ADC has no specification on this subject.
The current of the ADC input is very low it
only supplies the USB converter, the isolation
doing so after this converter.
In conclusion, I noticed that with a current < 20 mA
the HS02 caused problems.
I wired a USB socket with a 220 ohm resistor
and I put ADC + Resistance on a small USB HUB.
Problem solved up to 760kHz.
Regarding the temperature of the HS02 above 350mA/400mA
in my opinion it becomes excessive.
