Volumio on Khadas vim3l

Hi everyone, I have been using Volumio for just over a year now running on a Khadas VIM/3l with Khadas Toneboard. I have a Tidal subscription.

Am I right in thinking the VIM3l is no longer supported and I won’t be able to run the latest version with support for Tidalconnect?

I would like to carry on upgrading my streamer and hifi (maybe trying different DACs etc). Should I switch to a different SBC now? and if so is the RPi4 the best way to go for future proofing?

I’d really appreciate any advice, thanks
