I have some new speakers on order (Ruark MR1 Mk2) for my kitchen endpoint and they are replacing a Sonos Play 1, which will be moving to the bedroom. The Ruark’s only have two possible connections, via analogue aux in (3.5inch jack) or digital optical in via toslink. I have been looking at using a HiFiBerry Digi+Pro HAT probably using the toslink connection into the speakers.
Up to this point I have used a couple of Allo products as my endpoints (Digione and USBridge). I would like to put together a streamer running RoPieee, however I am unsure if I should go rpi 3b+ or 4. What is the general consensus as to which is better, the 3 or 4? I have heard arguments for both.
And finally, if anyone has any thoughts about Toslink vs aux in and which is best, then that would be helpful.
