First, you have to install the iFi ASIO driver...

 

[Sebastien Chiu]

if you have installed ifi driver it should show as separate audio device in roon. you just need to enable it

Yep, install our drivers, then you should be able to enable it in roon!

I have the mqa core decoder set to off, what do I need to set the mqa capabilities to, renderer and decoder or just decoder?

Just decoder!

I think that decoder + renderer is the right option. i assume decoder only is only for cases you want device only to decode mqa and send the signal to another device that is doing the final rendering. if you have headphones connected directly to diablo this is not the case.

Edit: I have just read Seb's reply, so I am maybe wrong.

The Diablo is a full decoder so there is no need for the renderer option! You can do either or, but our preference is to usually set the Diablo as a decoder.

Even if you tell Roon that Diablo is a decoder and renderer, it will still only do the final unfold (act as a renderer) when you enable Roon's core decoder. This is the appropriate configuration any time Roon's DSP engine is to be used, such as when I want to engage the built-in Audeze filters for my LCD-X.

So if you'd like to implement parametric EQ, for example, Roon will provide the first unfold and then send the MQA signaling along for Diablo to finish the decoding (with the designated filter for Diablo's DAC) after any DSP.

No signal processing in Roon when playing MQA? Turn their core decoder off.

All of these scenarios call for Diablo to be identified in Roon as both a decoder and renderer. Set it and forget it.

No question that roon mqa core decoder should be turned off. still, it is subject to everyone personal experiment but I enjoy decoder and renderer setting more than decoder only. eg. Taylor Swift's voice on Evermore's Champagne Problems sounds softer and more natural with setting decoder and renderer. It is too raw when decoder only. Listened with ASIO driver and AKG K872 Closed back headphones.

I found it! Def much better now. Switched over to the cookies & cream firmware. Sounds great. I'll have to try the GTO again with this roon setup, but so far I'm very impressed. Way better than just using tidal app. Soundstage & general sense of space and the clearness of vocals is impressive. Still think the GTO will be better for me but I am impressed.

For how many hours do you guys charge your Diablo with a supplied ifi charger?
The manual says that it should be around 6 hours

I my case it is definitely less, I believe it is about 3.5-4 h.

CMIIW, I think because it has auto discharge when it goes up to 90%
But yes, usually takes only 5 hours top even when it empty

So, iFi has made some changes to one of its most popular products. It is being showcased at the UK based What Hi-Fi? Virtual Show on 10am GMT on the 24th April.

To check it out, you need to go to https://www.whathifi.show/21/begin and register.

More on here next week.

you can turn off mqa core decoder to get full potential of diablo as it can decode itself

Hmm, I got magenta on Diablo connected to iphone and Tidal app playing Masters.
Manual says that Magenta is Original Sample Rate* - MQB? What does that mean? It should be an mqa file.
So it should be either green or blue...strange...

I will let them explain whatever "MQB" means.

The green and blue indicators confirm that unaltered MQA (green) and MQA Studio (blue) are delivered straight to the DAC.
When any processing happens along the way, but a legitimate MQA signal still arrives for final rendering, we get magenta (such as when software like Roon does the first unfold).

Your Tidal app is processing the streamed file within your iPhone.
