I always get dizzy when I read this pseudo-reviews (lower down on that page) about the different sound of different digital connections containing the same data.
To me this is discrediting an otherwise interesting project.

Sidenote:
I do a lot of A/B comparisons between different converters, amplifiers and other stuff.

I always do an exact level alignment, with a precision of up to 1/100dB, and always take measures to have a direct switching between A and B, usually blind so I don't know which one is which.

As long as nothing is broken and used within specs:
Differences between different electronic components exist, but are so minor that they are hard to detect and even harder to describe.

I even do the hardest thinkable test for AD/DA converters all the time in my recording studio on a daily basis as part of my job:
Comparing the original analog signal as it comes from the instruments or vocal, vs. AD/DA-ed through my DAW, this path running through different cables:
Result: no discernible difference even at 44.1/24bit!

For me it simply boils down to this:

Today it's fashionable in the audio department, in reviews, to swap cables, compare headphones on different amplifiers and on and on.
Of course, “there must be a difference” because everybody else is reporting differences.

If you don't report differences of (even digital!) cable's sound you are out of fashion.

These comparisons are made under shady circumstances, never true blind A/B (even if such would be simple with headphones on amplifiers), mostly with uncalibrated levels — but driven by the belief that the more expensive must be better.

I get angry when I think about how much money is spent to those cony-catcher selling cheap cables for huge amounts of money.

When this all started I invited some of those frauds, offering me cables and stuff,  for comparisons, but when I told them I will do true blind A/B none of them ever showed up here.

BTW: the first one tried to sell me mediocre microphones that couldn't hold a candle against my high class stuff.
As this did not work, he tried to sell me one meter power cables that would, as he explained, change my world of hearing.
He switched the cables on my studio monitors, no audible difference.
Then we change positions, I switched the cables and, of course, he could not determine which one was his and which one the standard powerline cables I normally use.

Please do not reply on this posting, I do not want to start a war!
I just had to get this off my chest.

Invitation:
Everybody is invited to come to my studio and proof the contrary, under controlled conditions in true blind A/B tests.

I'm sorry but I fail to see what this new information has to do with your opening post.

If the SOtM doesn't see the DAC when connected via USB, then most probably you forgot to set the DAC into Class Compliant mode.

Strange, it works for me all the time without any issues.

No, I am not spending any money for smth like this. It space becomes tight then I delete some files.

But its up to you, whether you want to give it a chance or not.

At the end with dropbox you can use this "dl=1" trick, so that graphics show up directly when somebody reads a thread.
With cloud storage from T-Systems that you get along with your DSL / VDSL offering this is sadly not possible.
Seems that they want to save Bandwidth...
And this seems to be the issue with other offerings was well. Therefore I recommend Dropbox.

Ok last comment in this thread...

@tcb ... sorry for hijacking this thread, but it was actually for supporting you .. so pls do not complain too loud, many thanks.

The URLs that you generate look very different to mine:

You: "https://uc28bfcb0f17af6b3a6141bf89b3.dl.dropboxusercontent.com/cd/0/get/A1Le9jFVce6pLwPHSYHy0eAxxhO2MGWW7Hd5_0UHvUrzIzqPl06hnnbS9-jU7ArnUN7zXUIRJcZWSr-sSqcrtzS7qodr-iCvxT-R5DBT9fOPC4SBsZafUPWrO2MLZC98rWs/file?dl=1"

Mine: "https://www.dropbox.com/s/syy0s9ytmnpq4i9/2020-04-03%2021_45_34-forum.jpg?dl=1"

Do you also see the green "ok" boxes that indicate that the file is on dropbox ready for sharing ?

You need to rightclick to a file, select share and then create the link.
But there are also general settings in the "linksettings" whether "everybody" is allowed to see the file.

Thanks Siemak for help :-)
This is what I was asking RME for.

I can't believe that RME send only the the Pro version and not also the regular ADI-2.........
Weird

Anything about RME sending ADI-2 dac to Roon,Please?

With a Roon transport (eg the Raspberry Pi Matthias linked above, or any hifi transport with digital out) it's easy to get audio from Roon into the ADI-2.
However, one bit of functionality is missing - volume control. Works fine with your hands but can't be controlled in the software.

Would RME consider a way to control output volume using the USB port? This could be controlled by a Pi, or Windows, or Mac - whatever - but it would mean Roon integration was complete as far as any DAC could be expected to. I for one would certainly buy an ADI-2 if this function existed.

Roon integration means not being able to playback only.

There is a process offered by Roon called ROON TESTED for DAC devices.

What ADI-2 is technically missing to fulfil the Roon criteria:

- Volume control by Roon via Device Volume
- Standby/Resume by Roon via via device control.

This is true not only for ADI-2 DAC but also for ADI-2 pro and ADI-2/4.

Best DrCWO

I am using the ADI-2 DAC with roon since I own it with zero problems. I am not missing device volume as I control volume via remote or knob. So I for one could not care less.
