H"D Radio FM/AM Digital Tuner
Sony XDR-F1HD
This is a $100 (thats no typo) tuner that blows away
the classic super tuners of McIntosh, Marantz,
Sequerra, Accuphase, etc., according to FM experts who
know more than I do."
He referes to this in depth technical review:

It had to happen - the complex, expensive analog filters in their IF strips
that made the classic high performance FM tuners what they were, get
replaced by a DSP that costs a few bucks.
Now, if there was only any reason to bother to listen to FM, except maybe in
my car. :-(
BTW car radios are the intended major market for this technology.
