The main thing the RX-340 has is the high dynamic range front end.
There is an IF output that has no AGC and little filtering to be used by an
external DSP processor. I hope the Orion would at least have the
RX-340 front end. The 16 bit DSP seems to work OK, but it would
be nice to have a 32 bit DSP.
