Sometimes people forgets our senses are accurate sensors. Making a direct comparison between the Analogue and Optical outputs is a clear evidence... no need to do ABX tests.What about Amir's own tests that clearly show the Analogue out of CCA is noticeably sub par to the optical with the right API?

I think you meant to say "believe" rather than "forget". Our senses keep deceiving us most of the time.
Can you trust your ears?
If you don't trust them, don't hear at music. They are the most incredibles tools at your disposal
Uh uh, that's what I suspected. I hope you have noticed the word "Science" in the forum name? Science is based on facts and verified evidence. Not feelings, subjective perceptions or beliefs.
So yes definitly you should trust much more your senses your senses

Should I remind Julf the first step in science is to proceed to experiences and tests ?
Finally I can also send you back to the original message, where I stated that the source of this improvement is in the low Dynamic impedance, statement that Professor Julf apparently didn’t even try to understand.

That sentence doesn't make sense.
Nice stereotyping / racism, but I am neither.
Should I remind you that the next step is to verify the experiences?
I asked you to explain / justify that nonsense statement. You never did.
For curious/openminded readers, I may enter in more details :
Should I remind Digital is another form of electronics,
and a bitflow has no existence by it self but can be represented (for instance in DSD) as a squarewave signal.
But as everyone knows, in electronic the higher the impedance the slowier the ramp-up and ramp down
This result, in the fact that the electronic gates converting in optical signal in the case of the CCA will work on a distorted signal, generating a lot of reading’s mis-interpretation. And transmit to the DAC a data flow with lot of mistakes.
For sure, the DAC may correct this, with error codes correction (if emitted by CCA) . But this is mathematics and no more music.
Unfortunatly as this is realtime music flow these corrections are just calculated, not based on the « anticipated » (although already available in the record) signal..
When I see the € we spend on good DAC, I invite you to make the test by your self both on CCA aswell as on you DAC if it allows.
Personnaly I use the 5V 4Amps on the CCA (and advise a 5V 10 A up to 24V 6A on your DAC if this allow external PSU)
I should precise I have no interest in Leicke I give as an exemple of good and basic design. I’m sure many others does exists. :

I let you refer to the memo I sent one minute before your'sDear Tades. Science is indeed about doubt as well as facts. If you suspect these differences exist that is fine, but it would help if you can provide a theoretical explanation for why they might. The next step is to test that hypothesis to see if they exist. Either by measurements that relate to known levels of audibility or by listening tests under controlled conditions ( i.e. double blind, level matched, near instantaneous switch over).
As you may have seen this is in the sarcastic part to try to imitate (not possible I've to admit) Julf agressivityMay I take offense? Unlike Julf I am Dutch. And unlike you I have no intention to engage in such stereotyping. And yes, I like France, I greatly enjoyed giving lectures at the College de France, and I was planning a bicycle tour there at this very moment.

There are definitely a lot of people who hear differences. People hear differences from lots of things. The question really is whether what they hear can be reproduced when there are controls on the testing.
For me. I have had CCA's hooked up to everything you can think of, including a lab power supply (it was handy out in the garage), and haven't ever heard a shred or hint of anything that would make me believe one was different than the other.
What now? My results disagree with yours. Does that mean I am wrong? My system(s) aren't revealing enough? Your decades of whatever give you the advantage?
Just because one has been listening for a long time doesn't mean you are immune to many overlapping and complicated biases that would need to be accounted for. Doesn't help with all the misinformation out there to encourage people to buy what they don't need.
As @Willem said, it's unlikely you could tell the difference between the CCA analog out and most any other DAC under most any non-pathological conditions.
