I am retired now, so haven't kept up withese things, or the state of the
art nowadays, but are they still using electromechanical relays for
front ends feeding a 16 bit A to D ?

Actually from a manufacturing point of view it sounds like they have taken
the matching board from a "100 watt" automatic tuner and converted it to
a preselector/filter board by chainging the programing on the controller
chip.

In this case the "the front end ...." stuff is marketing hype.

If they got enough of them as a close out, it would be a cheaper than
having to make one from scratch, no matter what was in it.
