I would like to say that with this connection option you lose up to 30-40% of the sound quality potential...

There is no difference in sound quality:
Study: Is I²S interface better for DACs than S/PDIF or USB?
This is an analysis of I²S interface to see if it is superior to S/PDIF or USB interconnects for audio DACs. From what I recall, it was PS Audio that popularized I²S for external DAC connections. Phillips (now NXP) had invented I²S years early as an internal protocol to route audio. It was...

You could use a DDC like a Gustard U18 or an SMSL PO100 Pro to convert from USB to I2S, but just be prepared to not be able to hear any difference.
What file player do you have on your computer?
It may sound convincing but it’s complete nonsense. There’s no audible difference.
I absolutely agree, there is no difference with Tidal and the like, I wouldn’t spend such amounts, I don’t understand, this is all at the level of Internet radio...

Nonsense.
Is high-resolution audio audible or not audible and a waste of data?
I have found several sites, articles and tests on the web in which it is claimed that the CD quality music distribution format, 16bit/44KHz, is more than sufficient to preserve practically all the characteristics of the sound compared to higher resolution formats. 24bit/sample and higher sample...

Seriously?
Okay, I don't want to have these discussions here, I don't have time for it.
I think that my test with Topping D90III Discrete will be useful for those who want to know something about the quality of this rather unusual DAC.
I also really hope that my message will be read by people from Topping Audio.
I also want to thank them for making a discrete 1-Bit DAC, which is apparently much more promising than R2R DACs.

You have seriously come to the wrong place to spread this nonsense. All DACs sound the same
How can DAC's have a SOUND SIGNATURE if they measure as transparent?
I know there are people out there that think cables affect sound, which is much worse, but there really is no response to something like that, but just to smile and nod. But what about people who talk about DACS as if they were headphone drivers or speakers, and talk about the SOUNDSTAGE...

I installed new software, and the sound quality is much better now. The Topping D90III Discrete needs additional amplification on the XLR output. With my Gustard P26 and the +6db preamplification enabled, the sound quality is fantastic. I'd compare it to the good sides of a 4499 mixed with the analog sound of a tda1543. So, today I'm really impressed with the quality.
When will we test it, Amir??
This is exactly the device that needed to be tested right away, and not these already boring and useless R2R like Centaurus. In discrete technology, you can do really well only in 1-Bit DAC technology. Resistor matrix are extremely unstable for audio conversion...

Of course, in a lab environment this is expected.
I use a Pi2AES / Raspberry Pi5 and can simultaneously stream to USB, AES, COAX, and I2S inputs.
These can be switched fairly quickly and the all sound a bit different.
There chain looks very different than a lab. Roon. Should they sound the same, yes, do they, no.
I doubt there is any interest in this topic because no blind tests etc.
There is also a bias here where is it important to have a science based metric, I’m for that and support the site.
Many great things are measured, but not all things are measured.
Even temporal issues can occur, where new firmware changes the device performance.
I reported 2 such issues on the D90 III Discrete that are now fixed on 0.50 and 0.51 firmware updates: the I2S level and level drop in 0.49.
I supposed I could just find the review and lost all interest, it cannot be wrong, look at those measurements

Actually, I2S is WORSE, as it was never meant to be transmitted in a cable, ONLY in traces on the PCB.
I wonder whom invented that stupid thing (I2S on a cable).

It's a chain reaction.
It started with DIYing ESS9018 and the new USB>I²S modules that went out at about the same time (XMOS, Amanero, etc) .
From then on traces became short wires (<5 cm was recommended) , then got longer
What people do not get is that the external USB>I²S "bridges" are the exact replica to what already exists internally in a DAC.
