SDR-14 vs SDR-IQ

I'm trying to reconcile why the SDR-IQ is so much cheaper
than the SDR-14
the high-performance ADI parts in both of them are identical -
the A/D and the digital downconverter
the data delivered across the USB2.0 interface is essentially identical
the -IQ has *more* filters and switching
the -IQ has *more* computes and digital hardware
as a result it's hard to understand how the BOM cost of the -IQ
is really any less than the BOM cost of the -14
yet the selling price of the -IQ is *half* of the -14
true, the -14 looks to have a slightly spiffier case,
and it might have a more stable, less noisy clock part,
but that doesn't justify a $500 delta in the price
what am i missing in this picture??

If it was easy, we'd be buying it from somebody else!"
