I have scrapped the RPi idea. Doing more research at the moment but been looking at Allo Sparky SBC with shield board or better yet, Allo USBridge Signature with Digione Signature in metal case and linear power supply. Might use the Allo Shanti instead of the Slee 5V 3A PSU. I am undecided.

After inspection of the USBridge Signature, maybe, as I suggested before, USB may turn out to be the best interface for audio data stream.

Graham, promote your 5V 3A PSU to me. What will it do that the Allo Shanti might not? I probably won't be able to hear a difference.

I still intend to get the GSP 5V 3A PSU and a Allo USBridge/Digione Signature player, to stream audio from a computer or smartphone to my Majestic DAC. Do I have to set up the streamer as a wifi/Bluetooth device? This is new territory for me.

The Allo USBridge will need to connect to your network, either by ethernet cable or WiFi depending on exact model. Bluetooth can be used for output to or input from other audio devices, although sound quality is compromised.
Ethernet/Wifi connectivity is needed for control of the player from PC/Tablet/Smartphone and access to streaming sources. Music files can be stored on an attached HDD, SDD, PC integral HDD or NAS on your network.
A further option for controlling the player is a touchscreen.
Which Allo version are you proposing to use, is it still the all-in-one USBridge Signature player?

Just listen, if it sounds good to you, enjoy it.

USBridge Signature player, yes. Will have the Digione Signature added to it in case I want to stream over coaxial to the Majestic rather than over USB. Thinking of having my CD FLAC rips on a high capacity flash drive plugged into one of the USB ports and the Slee PSU powering both boards. Would use a phone or PC as a headless controller. So the actual data stream would not be wireless; only the control of what data to send would be wireless. If I could connect it to PC to play youtube videos, that would be great too. In the case of youtube streaming, audio goes to the PC/smartphone controller over wifi then is transmitted to the Allo boards over wifi, so both control and data would be wireless.

What about playing Blu ray or DVD media or video games, either on console or via emulation? The audio data could still be sent to the streamer/GSP signal chain over wifi? The Pi3B compute module is only 1.4GHz so is fine for audio, but probably insufficient for both video and audio? Regarding super hi-res formats above CD, it would be nice to have compatibility with those too but it isn't a necessity.

Providing the Blu-Ray/DVD/Games console source has discrete digital audio and video outputs the audio stream can be sent direct to your Majestic, the Video direct to monitor/TV.
If the source has uPNP/DLNA capability then "WiFi" connection to the Allo is possible, providing the OS you use has the capability.
The Allo along with most pi or SBC based streamers is aimed solely at Audio processing, keeping it isolated from video signals.
The pi has more than enough processing power to deal with PCM audio of at least 384kHz sample rates and similar quality DSD audio.
Just listen, if it sounds good to you, enjoy it.

Just going to wait a bit longer and sell some things while waiting for the 5V 3A GSP power supply then I will bite the bullet.
