I can't see why these posts shouldn't be allowed, it’s in the HiFi & HT Chat section.
I'm quite interested myself how this stuff would actually hang together since I would want to keep Roon as the front end UI. I'm pretty sceptical on these sort of optimisations, I personally haven't had much joy with upgraded cables etc. As someone mentioned Diretta themselves don't do themselves any favours with the available documentation.
But from a practical standpoint, if I can get a sensibly priced Pi based alternative to an "808.6/ID42", I'd be in, even if the performance is break even. The old Meridian hardware is all obsolete now so need a plan B for when the inevitable happens.
Cheers
