Good evening. Please let me ask a question: is it worth implementing the Diretta Protocol to Roon on my Sonicorbiter?
How can it be done?
Do I have to use special hardware 
Thx and best readings
Kind greetings
Michael
Roon doesnt use that protocol.

There is also no advantage to using Diretta, donāt bother with it.

Have you already tested it in your system? Friends of mine were really convinced about this new protocol with regard to soundquality. Up to now, I have not tested it by myself.
Nope. I did not test $700 audiophile fuses either.
Direttaās description of the protocol makes even less sense than the justification for those fuses (but I will cut them some slack, English isnāt their native language), but it does not solve any problems that exist in the real world.
Given that Roon definitely does not support the protocol, and Sonicorbiter does not seem to eitherā¦ You could spend some significant time hacking together a system that would use Diretta from Roon to some kind of player. It would not be any better.
Thatās a polite way to say it. A less polite angle is that it is complete BS with one and only one purpose ā to separate you from your money.

I looked at Diretta some time ago when it came up on a forum (possibly here). I read a bit through their material, but could not understand how it could be worthwhile. The copy reads as marketing material with pseudo-technical jargon thrown in. I have not seen a spec, but it appears to operate in the digital domain.
One can easily object to the various digital transmission schemes, but modern DACs have solved the many issues related to legacy digital formats.
Am I wrong?

Haha ā¦. Thx so much for your honest words
I would recommend that you actually listen to Diretta before making a decision.
I have had the opportunity to compare RAAT and Diretta on four different systems, including my own, and Direttaās sound was by far superior.
RAAT is a superior transmission protocol compared to UPnP in general, but Direttaās low load fluctuations during transmission are overwhelming.
Although there is a hypothesis that noise during transmission is suppressed, it seems that the stable transmission load suppresses power consumption fluctuations in downstream DAC-side electronics, which contributes to the improved sound quality.

As far as I understand it is necessary to have a server diretta installed and a USB bridge with two rj45 input? Is that correct? Or have you implemented diretta by yourself? More Infos welcome

Yes, you need a server with a Diretta host installed and a USB bridge that will be the Diretta target. the USB bridge only needs to have one RJ45 port.
I am using a Linux based platform called Gentooplayer for the host side, and the Diretta target side can be configured with the same Gentooplayer OS on Rasberry Pi or X86 PC.

Thx so much!
That image you posted is for server-to-DAC, both with Diretta implemented internally. If thereās a bridge or streamer instead of the DAC, you lose the purported benefit of Diretta, so why do that?
But itās all hokum anyway. My understanding is that the core idea came in a fever dream to a Japanese poet, and someone actually built it, anyway. More nonsense.
Youāre welcome.
Oh, and of course you did a proper blind, level-matched testing, right?
This is Synergistic-level meaningless ā ā .
This is an experiment I did to observe the RAAT and Diretta signals in my current setup.
Of course the sound comparison was done with the same DAC/Roon ready.
In my main path the Diretta signal is converted directly to I2S, but when doing the sound comparison the Diretta signal is converted to a USB transmission.
Still I find the effect of Diretta to be noticeable.
For those who are interested in Diretta, I have presented some of my personal impressions and some data to support my argument.
I think it is strange for someone who has never heard Diretta and has no logical explanation to criticize Diretta categorically. And the argument that the technology is of Japanese origin has nothing to do with the sound quality. Most nonsense.

Ah, but I do. The logical explanation is that I read the bogus explanation of how Diretta is supposed to āimproveā SQ. Hogwash.
Sure. Of course, if you think that cultural context has no influence on theory, you havenāt listened to enough music.

I primarily use Diretta technology to appreciate the wonderful cultural heritage recordings in Europe and North America in the late 50ās and 60ās.
I donāt know what the bogus explanation is that you have read, but if we are going to discuss it here, I would appreciate your opinion on the data and arguments I have presented.
Many thanks.
So basically, no worthwhile comparison tests were performed.
No, thatās not the argument./ The argument is that the technical description of Diretta, presented b y Diretta itself, it complete and utter nonsense. There is nothing in this protocol that could have any effect on sound quality, and the āexplanationsā that they give either mean that they themselves do not have any idea how networks, DACs, IP, etc.etc. work, or expect you to have absolutely no clue.
As far as I know, Direttaās official claims can be summarized as follows;
Noise reduction is achieved by transporting and averaging data over a constant and short period of time.
I have shown earlier with data that this is true.
If you donāt understand what this means, then you may know a lot about IP and networking, but you donāt understand the essence of digital audio.
By the way, do you agree with the importance of clock jitter during DA conversion, as represented by femtosecond clock, which is now advocated by DA converter manufacturers around the world?
If you say this is also stupid, I would like to end the discussion.
Thanks
Nope, sorry, you didnāt. Neither did MegaTech.
I am afraid it is Diretta that does not understand it. Until it hits the DAC chip, digital audio os just binary data.
This isā¦ well, it is not stupid. For manufacturers of mediocre $20K+ DACs it might be important as a way of selling another $10K+ worth of useless doo-dads. It is not recommended for decent DACs because jitter has not been an issue for decades now. It is also not related to Diretta in any way.
I am not familiar with MegaTech, but I hear this comments often.
[Moderated]
You also seem to be unaware of the importance of the clock jitter during DA conversion, so I will refrain from further discussion.
However,
It is also not related to Diretta in any way."
is wrong. I believe that a uniform Diretta signal plays a role in suppressing jitter during DA conversion.
