Yawn same **** different day. You do have such a limited imagination Fill

That is strange because Sony only considered it a medium quality product,

Translation: something that doesn't fall in line with your rather
twisted beliefs.

as the name indicates - 101 binary for 5 or 5 out of 10. If you don't
believe it check this link:-

ROFL, I think that I'd take Sony's version of events over what Fill
would like to believe any day.

It was of course *Philips* who originally conceived and developed the CD
system, inviting Sony into the game at a late stage and so Philips had
priority in model naming. It was simply not on to both of them use the
number 100 on their first models.

The CD100 model Philips developed was very basic with few features ( not
even remote control) - plus it employed 14 bit D to A converters cos
Philips simply had no 16 bit ones available.


It is without doubt that Philips originated the CD, but they realised
quite early on that they could not bring such a radical device to market
on their own. that led them to choose Sony as a partner, quite early on
in the process, the first demonstration unit that Philips took to Japan
was an all discrete component lab model. It was Sony's suggestion that
the sampling rate of 44.1Ks/s was chosen and also the 16 bit resolution.
The also contributed the error correction code system. It was at Sony's
insistence that the 120mm disk holding (at the time) 73 minutes of music
was set as the standard. All this went into the making of the "red book"
which had to be settled before anybody could design a commercial product
so you can hardly say that Sony came in at the last moment.

However, Sony's engineers took a little longer to finalise their first CD
player design, producing a very different product from the Philips
achine - the fully featured CDP101 was anything but basic, it came with
the lot.

Sony also elected to develop the first true 16 bit D to A converter IC for
the CDP101.


Sony already had 16 bit converters which is why they pushed for that
resolution in the standard

Sony were clearly out to "upstage" Philips with their first CD player and
succeeded.


Certainly the CDP-101 was better than the Philips unit, but Sony knew
that much better could be done so they considered it to be a medium
quality unit.
