Joe, I know this thread was closed earlier today, but I just wanted to clarify that the IC-7300 is a "pure" direct-sampling SDR. The architecture that you described is more in line with direct-conversion SDRs such as the KX3. 
I also asked myself why ICOM did not go the extra mile and provided more than one receiver on the IC-7300 since the whole spectrum is available on a direct-sampling SDR. The only reason that occurred to me is that its FPGA is not big enough to handled/process the stream of data arriving from the ADC that is necessary to produce more than one of receiver (slices).
