I would start with the Pi4 via USB into the Hegel. This should provide a nice upgrade over the Airport Express.
This will be inexpensive, easy to do (just install Ropieee ) and won’t suffer from the USB issues of earlier Pi’s.
You can always try a DigiOne in the future, adding this to the Pi4.
Thanks, that resonates well with my initial plan. I’ll try that first.
This is so exciting. I have a large FLAC library from the Squeezebox era (pre Logitech). It’ll be nice to browse it in tandem with Tidal and seemingly really nice endpoints (ropieee).
I actually already ordered an Allo Boss for my Genelec speakers by the computer. I’m looking forward to decouple the Genelecs from the Macbook to be able to play on them even if the Macbook isn’t started.
Fortunately I will need more endpoints. I’ll order an Allo DigiOne as well. Will do some A/B testing and maybe learn something. The best of DigiOne and plain pi4 will go into my main room with the Hegel.
Have fun. And maybe consider a better power supply than the standard RPi one as and when …Allo and iFi both do one around £50. Same with the Boss - my son uses a Boss and once he tried the iFi with it there was no going back. And he’s an absolute newbie to the hi-fi game.
As a fellow long time Squeezebox user (since 2003) welcome to Roon!
Like you I was blown away by Roon during a trial run and had to make the move.
I’m using USB, but since the Hegel limits that input you might want to go with coax.
