The black tray obviously filters reflections of minute variations in the
heat dissipation of the mechanicals- thusly damping the natural
heat<->motion resonances and achieving a 200dB reduction of this
aggravating effect...

I think it works on the same principal as the fancy-marker around the
edge of the CD, monocrystaline super-high-resolution cables (especially
for digital signals), and capacitors rolled on the thighs of virgins.

This principal was the subject of much research by an American
researcher in applied psychology and social dynamics by the name of
Barnum, and has been applied quite profitably to psychoacoustics, as
well as to many other fields.

Just might keep room light off the pin diode detector, but the data is
reclocked by a PLL so it wouldn't matter anyhow. Sounds bogus.

I have a Plextor CD burner. Plextor is good stuff IMO and this looks
like a nice DVD burner.
How aggravating is it, Fred?

ROFLMAO, Tim.

ROFLMAO. That was good. Just after reading that "capacitors rolled
on virgin thighs" comment, too.

This is a spoof site, yes? I can't believe anyone would actually
purchase a pair of 3 foot "Dreamdacer Ultra RCA" cables for $8,500,
would they? :0

Perhaps they're not actually suggesting that it's the colour
of the tray that reduces jitter.....but it sure sounds like
it.

I do a fair amount of electronics work in Hollywood recording
studios, and I assure you that customers for this sort of thing
do exist. See http://www.stereophile.com/asweseeit/182/ for an
example of one side (I am on the other (AES) side myself...)
Also see http://www.epinions.com/content_2815402116 and
http://www.audioholics.com/techtips/audioprinciples/interconnects/snake_oil1.php

BTW, 50% discounts on such cables are easily obtained.

I honestly don't know. One of my hobbies is vacuum-tube radio, so I end
up finding a _lot_ of vacuum-tube audio sites when I do web searches,
and those people certainly have a different view on what constitutes
'sane' than I do. Furthermore but I used to work with a guy who was an
engineer with a So-Cal company making professional audio equipment. He
assured me that whatever I could come up with to spoof them, they've
already surpassed in reality.

Certainly it wouldn't be a big stretch for the pair that I knew to go
from Monster Cables that are merely large copper ropes to
nitrogen-dipped Monster Cables (note that I'm being unfair -- Jena Labs
does not merely dip their stuff in LN2: they bring it down to
temperature and back up in a controlled fashion that enhances the
alignment of the crystalline boundaries).

You could always order some and find out -- do a listening test while
you're at it.

They certainly would, but in a blind test they will surely fail to
appreciate the big bucks spend

As a side note I have a friend that has 200$/meter speaker cables - I've
stopped discussing that because that wont do any good for our friendship

Hello John,
a PLL has only a limited gain at a certain frequency. So only some
fraction of such noise(@120Hz) will be eliminated depending on the
openloop gain and bandwidth of the PLL. Reflected laser light will
also be better absorbed by a black surface.
Maybe this black tray makes really an improvement as advertised.

Best Regards,
Helmut

The signal from the CD is not a reference for a PLL! The output
(sample) frequency of a CD player is set by the fixed frequency xtal
osc on the motherboard, nothing else.

There *is* a PLL, but it controls spindle motor speed to keep an
internal buffer (FIFO) about half full. The audio is read out of a
FIFO at a crystal controlled rate.

So, the jitter on the signal from the CD is completely irrelevant, as
long as it isn't high enough to cause an uncorrectable block error.

Can you say "snake oil"?

Allan

Audiophiles are against blind tests because they would never agree
to going into a purchase blind...
