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

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...

Well of course they're ridiculous, yet another example of people treating
CDs as if they were records. I mean, seriously, these things must cost
10p to make, if they did anything they'd come built into most new CD
players anyway!

Then again, in light of the OP's

a good few years ago you
could buy "ring" thingy's that went around the edge of a cd (stuck to
the top), which reduced vibration. I have one on my copy of Brothers
In Arms, and it does improve the quality."

I'm sure he'll hear another great improvement in sound!

As long as the "thingy" is of sufficient thickness to prevent the disc
from rotating in the drive ... this will *definitely* improve the
sound of any Dire Straits album :-)

Oi! I quite like Dire Straits! In fact I found out something quite strange
about Dire Straits' "Unique" sound....

Whilst on the phone to orange with dire straits playing in the background, i
noticed that without pressing any buttons on my phoone, i was getting put
through to different departments... It turns out that Dire Straits' guitar
sounds very similar to DTMF tone signals...

Private Investigations got me through to the roaming department without
pressing a button. Random.

Being the original poster, I did say that I thought they would
probably be crap. The theory behind the vibration reducing things is a
good one, and they didn't cost the earth to find out.
I can hear a difference, simple as that - it also spins slightly
quieter in the drive. At 50 pence a throw, it's worth trying - the
stat mats at nearly 40 quid aren't.

the info on a cd is digital - if some fault is stopping the signal getting
through you'll soon know it - it will be that nasty noise (not the dire
straits nasty noise- -the clicking one).
so unless the magic ring is reprogramming the signal via a tiny hidden pc
any perceived difference in sound quality will be in the analogue domain -
your amp.
