He referes to this in depth technical review:

I answered:

The technical review cited doesn't support audiocritic's claim.

oustor sez:

Did you read the full article of the 'audio critic'

Yes.

If not read it, therein is his
full review.

The full review does not support the claim. It compares the Sony to a
Sangean HDT-1X, and never cites any measurements made from the
supertuners mentioned by audiocritic. Perhaps the Sony is all that
audiocritic supposes, but there's nothing to support that in the review.

Moroever, the review cites shortcomings of the Sony:
does not display carrier-to-noise ratio, HD Radio transmission mode, HD Radio station ID, firmware version, or the audio spectrum. It does not provide forced mono, forced analog, split-audio mode, direct frequency entry, or digital output. It does not have a stereo indicator

It's all probably moot, however, because so few people care about the
very, very lo-fi HD radio scheme. Even broadcasters are reluctant to
invest in HD radio programming. Mostly, HD radio is home to cheap
automated formats that have already failed on conventional FM.
