Default StatMats for CD's/DVD's - Do they work?

In anetnews.com,

Hi,

I came across these "Statmat's", and was considering the CDi Blue -
does anyone have any experience of them - do they actually live up to

Hi

Crossposted this to uk.rec.audio as there are people in there much more able
to comment than I...

Just my 2p worth but they look like complete and unadulterated bunkum to me!

According to the blurb on the website:-

"When static builds up on the CD, it can interfere with the interpretation
of the digital information. This means that, when the digital-to-analogue
conversion takes place, an impaired signal is produced."

"Electrostatic build-up introduces continuous electrical vibration,
resulting in phase changes. If strong enough, this vibration can cause the
phase to shift 45o, 90o or even higher and could make the absolute phase
appear inverted.

These phase anomalies can affect the timing of the music, with disastrous
consequences on the quality of the reproduction. The timing of notes is
crucial to the experience of music."

They are making the completely incredulous and utterly unfeasible statement
that phase anomalies in the transport can result in phase changes to the
decoded audio.

I love snake oil...

Steve
