Stealth Mat indeed :-)

It's a valid EMC technique, just a silly name for it.

You'd be be hard preseed NOT to dither a 24 bit recording - LMAO !

Silly beyond extreme.

I intentionally didn't look up the reference since I was much more
interested in your interpretation of it.
"24-bit audio is sometimes used undithered"

Is mine a misinterpretation?

Well .... if you had a source with 144 dB s/n ratio it would be undithered.

Got it yet ?

Got what?

In order for a signal not be 'self-dithered' by its own noise floor, the source
would have to have a s/n ratio of 144dB with a 24 bit converter.

I won't go into how utterly unfeasible that would be.

You are all FOOLS.

No you claimed to hear a particular sound which seems, from the
explanation from the railway signalling standards, to be similar in
nature and you also said that you had a recording of it somewhere and
that IIRC you were looking it up?.

And I found it..

In which particular way would would you like to eat your words ? Shoved down
your
wretched throat I hope.

Well this was a quite sensible argument but if you have the resort to
the same abusive level as him down there, you can shove your disc up
your arse as far as it will go!......

I thought you were joking. So this 'strategy' is valid, and will lead to
better reproduction of fine detail in your opinion:

"Electromagnetic interference (EMI), which would normally mask fine
details in similar players, is dramatically reduced using Arcam’s
proprietary “Mask of Silence� strategy. The use of “Stealth Mat� (unique
metal fibre matting) further diffuses EMI to ensure the every nuance of
each recording is heard in its full glory."

This may be meant to be "EMI of a type that would 'normally' mask..." So is
selecting some types of EMI on the basis of defining the effect which would
be a symptom of the class of EMI mentioned.

Not at all clear what "diffuses EMI" means here. May simply be a misuse of
English. My understanding is that the idea would be to absorb or reject EMI
depending on source location, but dunno if that is what they mean.

FWIW The only thing I've noticed about the Arcam DVD player I'm using us
that the levels of *mechanical* noise it emits is very low. So you don't
hear any hums, buzzes, whooses, etc, from it. Given that other players or
recorders I've tried made quite a din, this is a plus point for the Arcam
in my view.

Slainte,

Jim

Whatever it is or means, the 'ensure every nuance is heard', as opposed
to not heard if 'it' is not in place, is pretty unambiguous to me.

An old Marantz CDP I had made a bit of a noise, audible from a few
yards. The Denon (quite expensive) and Akai (£30 cheap) DVDs are more or
less silent, as is a newish 180UKP HK CDP. Mechanical noise gets on my
nerves, and strikes me as sloppy engineering. The noise floor of my (how
to put this) downstairs hifi is set by a REL subwoofer, a sort of hum
that doesn't change with volume - vibrating transformer I suspect.

My 206, which has the same transport etc as your 200 also
struggles with CDRs in the same way. Mine will usually,
but not always play a CDR all the way through, but won't
allow me to select tracks, or to jump from one track to
another. It has never been happy with CDRs from when they
became available so I recently sent it back to Meridian
as I wondered if the laser was losing strength. They told
me that the laser was fine, the player was still to spec,
it was just never designed to play CDRs, as they didn't
exist when the 200 series was designed.

Ironically, I know of 2 CDP 101s that are both still fully operable, and
they both play CDRs quite nicely. I believe that they were on the market
several years when the Meridian 200 was new. Talk about CDRs not existing
when they were designed!

The stategy is certainly valid, no doubt. I've even done similar things myself.

That's the subjective bit, but is is *possible*.

Bear in mind that's the Marketing Dept's presentation of it. I'd have described it
differently but it might have sounded boring.. It would not surprise me if there
were a measurable difference. ARCAM aren't like your average hi-fi liars.

Do they still cut off (truncate) reverb tails the way I recall ?

It doesn't mean, however, that the CDP101 was actually *designed* to work
with CDRs, it just happens to do so. The 200 series Meridian wasn't and
doesn't.
