Not sure what ProJect can provide outside of any other Pi based setup, not sure though
From what I read they add a lot of tweaks that we could probably do but likely wouldn’t. Could be wrong, but ProJect knows a helluva lot more than I do so I’d bet they’re adding some pretty significant value. Just a guess though. But, and like I tell my wife it’s a big butt, how it compares to the iFi at about half the cost is the big question, at least to me. Again, I’m strongly leaning to the iFi but am willing to learn as well.
