I definitely don't want to argue, but I think it matters.
The world's best $100K external clock will still lose to a basic budget clock that's placed on the DAC's PCB directly beside the DAC chip (minimal trace length).

Notice how GoldenSound didn't measure SU-6 + DAC vs DAC alone, because he would've seen no difference.

In a consumer environment, external clocks serve zero purpose.

Anyway, I'm not bashing the RME product here, I wouldn't dare. I'm just trying to find the right synergy between all these instruments. And I have to admit, after adding the SU-6 to the audio chain, it now plays very, very well indeed. That's why I thought it wouldn't be bad to use the I2S connector, so I asked a few questions here if anyone has specific experience with it. SU-6 + another DAC connected by an I2S cable. That's all.

If I express it in just one sentence, the music sounds much more transparent and detailed to me. I'm not saying that's a change for the $700 price, but there is a definite change here and I can hear it. But I'll give it time to settle in, I don't want to jump to any conclusions. So let everyone make up their own mind about it. Maybe it can be in something else. I also bought a new Pangea power cable, connected a new headphone cable.

I'll digress a bit more. I found some pretty good reviews on the Aune S17 Pro Headphone Amp. Might be worth a trade for my Singxer SA-1. Both are amplifiers working in class A. Of course, I am talking here about an amplifier within financial possibilities. Maybe someone has the money to buy the Feliks Audio Euforia Evo tube headphone amplifier.

No, there is not. That's all in your head, I regret. And I'm not talking about the Singxer Vs RME headamp, where there's logical explanation why you hear differences. A S/PDIF interface can't change the sound of a good DAC. Otherwise, it's a bad interface.
So let everyone make up their own mind about it.
Nope... let's not do that. Seems like you don't really understand the way this place (ASR) works. This is not a forum suitable for arguing opinions about imaginary differences being existant or not. If these differences are there, they have a technical explanation for it (meaning : we can measure it). And I'm not talking about subjective preferences regarding headphones or speakers.

Again : There's no audible difference between USB-In and S/PDIF Inputs of the ADI-2 DAC with whatever S/PDIF interface you would put behind it. Sorry if I haven't made myself clear until now : that's not a debate, but a fact.

I also bought a new Pangea power cable
Now, you must be joking.

Sure. Cause you can't, really.

OK. I understand that everyone likes to reach for measurable results. I'm also looking for measurements of the given devices here on ASR, at least for comparison (so that you don't buy a rabbit in a bag, as they say). But sometimes the measurement itself is not everything. The device does not have to be in the TOP10 to be able to play at its best. And in the end, the most important thing is to have a good feeling from listening to music :)

Sorry if I'm breaking the rules, but this song is really my favorite:

If I only connect the RME via USB, then the maximum settings of the audio device can be used in MADIface: 384kHz sample rate and 16384 samples buffer size (latency).
If I connect the USB to the Singxer SU-6 (no driver, just plug and play) and connect a coaxial cable from it to the RME, then the maximum playback in Win 10 can be used in the sound settings: 24bits/192kHz.
Haven't used Tidal, Spotify or foobar2000, AIMP2 yet. I'm currently playing music via YouTube.
This is by design, as spdif is limited to 192kHz, whereas USB does whatever you throw at it (almost). You also want to keep the buffer as low as possible.

Because I use Apos Flow balanced XLR cable for headphones.
What headphones that the RME cant power single ended ? I have a THX 789 amp strapped to my RME but only use it for the Hifiman 6 SE via balanced output that the RME is just a little underpowered for. Everything else I can play from the RME directly and most HP I play at below -10db on the RME- plenty of headroom for things like the high impedance Senn HD800 and Beyer T1

There are perfectly valid use cases for a DDC. You need one whenever a target device does not take the signal of a source device. My speakers use AES/EBU as an input while my streamer outputs to USB. This is why I use a DDC. That's all there is to it.

Yes, unfortunately transmission via coaxial cable is limited to 192kHz. Exactly the same as the optical cable. Ideally it would be via AES/EBU. Or the already mentioned I2S, with which I have no experience at all. Only from reviews written by other users. In fact, it is not a completely standardized protocol. But the SU-6 manufacturer states for I2S: PCM up to 32bit 384kHz, Native DSD up to DSD512. I am guessing that AES/EBU will have the same bandwidth.
Unfortunately, the RME ADI-2 does not have an AES/EBU input, only higher-end models have that. RME is equally limited by DSD up to DSD256.

Why do you think upsampling youtube and sending it through different digital connection types will yield better sound from your headphones/ monitors than playing the native sample rate of the file through USB to your RME?

Um, I understand. HiFiMAN HE6se headphones are difficult to play, they have a slightly higher impedance. I just read this independently from several sources. But if the amplifier plays them, they are said to be very good headphones. Can you please write me something more about them? I pondered over them for a while. And I'm also still considering the HE1000se. This would be a mega upgrade of the headphones :) Even though I'm actually currently satisfied with the Arya Stealth I have at home. I have the RME set to -6dB when I use the Singxer SA-1 amp with them. I set it up according to the instructions from the RME forum. And I'm using oratory1990's PEQ setup in RME for the HiFiMAN Arya Stealth. And Arya Organic won't make such a shift again. Maybe a different brand. I haven't heard Meze Empyrean play either.

Good question. I don't think so. I know it's not ideal at all to play music from YouTube or Spotify. It is important to have a quality recording in good quality, for example FLAC or a quality recording from Qobuz. But then there's also Loudness War. So if a person had to deal with everything in absolute detail, he would also have to choose between individual recordings, remasters, originals, etc. I am not dealing with this at all for now.
Here it depends on what you choose. Either listens to digital music via PC, streamer. Or it goes the analog route via gramophone records and gramophone, CD via SACD, etc.

Which in no way answers my question.
You seem hell bent on upgrading /changing /tinkering with the electronics part of your chain.

Meaningful improvements in your audio will be found in EQing your headphones and treating your listening space and /or eqing your monitors.

Optical by spec is limited to 96 kHz, AES/EBU maxes out a 192 kHz.

This has already been asked: Why bother with a ddc? It just doesn't make sense.

The singxer is not really a class A amp. If you really push the amp it will switch to AB. (Not that it makes a difference).

I also use the singxer SA1 and a SMSL SP400 (thx amp) and there is zero difference in soundquality.
