My new Armchair has arrived 
Now I need a small table or rack AND Roon ready devices.
I was thinking about Volumio Rivo Plus as streamer (Roon Ready). Has WLAN and Ethernet.
Than a headphone DAC/AMP.
If the streamer is Roon Ready does the DAC/AMP also have to be Roon Ready? I think the answer is no, but I just want to be sure.
The goal is to control everything (including volume etc.) from the Roon App (iPad)

No, but maybe consider a DAC that is Roon Tested.
Why do you suggest that?
There are not many headphone DAC/AMP’s that are Roon Testet or Roon Ready.

Note, not all DAC/amp via USB will allow for hardware volume control.
If I use a RPi4 running RoPieee connected to my Mojo2, Audiolab 8300CDQ or my FiiO R7 it does not control the volume at the hardware level, but can via DSP. Same applies here if I connect my Roon server directly to these DAC’s.
With my Dragonfly Cobalt DAC/amp it does control volume at the hardware level.
Both the Chord Mojo2 and Cobalt are Roon Tested, but not equally so.
As a self contained Roon Read endpoint, DAC & headphone amp I highly recommended the FiiO R7. Form factor may not suit all, but it’s great features and capabilities of running Android apps makes it very versatile. There is the R9 as well.
There are negatives either the R7, such as very slow update cycles. 1 update since I’ve had mine (nearly 2 years).
It depends on what you like. Multiple boxes for a granular setup and tastes, function such as volume or convenience.
Note: Roon DSP volume control is very good.
You might be surprised. Take a look at the Roon Partners page. Think of a DAC manufacturer and check out their lists of equipment. 
Love the chair and “The rug really ties the room together”
No budget
Naim Uniti Atom HE , perfect just add power , network, and a pair of headphones , maybe even the focal Clear Mg
Minimalist but …
THX Mike. This could have been a solution, but currently not the right option.
The whole Volumio eco system looks very interesting.
Never had a Roon Ready streamer before, so I need to understand who this works with a headphone DAC/AMP that will probably not be Roon Ready.

What about the MATRIX AUDIO MINI-I PRO 4?
All-in-one box solution, roon ready, WiFi, so you only need power.
I have the predecessor mini-i pro 3 and absolutely love it for headphone listening.
You could go the cha.in of boxes
Rpi Ropieee streamer then USB to a DAC .headphone amp. The Audiolab M..DAC is an option
I chose the Naim because it was all in one box
Torben - The output from your Roon Ready streamer will a digital music file. Your DAC does not care about the origin of that signal - it could come from your Roon Ready streamer, a non-Roon streamer, a CD transport, smartphone, whatever. You could send the output from a Roon Ready streamer to any DAC, DAC/AMP, or other device you desire. There many Roon Ready DACs and DAC/AMPs, so you do not need a separate Roon Ready streamer unless you are committed to buying (or already have) a favorite DAC that is not Roon Ready.
Is your (very nice) armchair Roon ready or just Roon tested? Or are you just taking a chance re compatibility?
Thanks Mark.
Right now I am considering Volumio Rivo Plus streamer (Roon Ready) and use this with my iBasso D16 DAC/AMP (not Roon Ready or Testet).
Later I will buy a non-mobile DAC/AMP or DAC and AMP. Maybe Roon Ready maybe not.
Just want to make sure that I am not “locked” in my decision-making process
