I think that we should put things about digital and analog sound into
historic perspective.  The most recent analogy of what is happening
today between these two formats is the introduction of the Phillip's
cassette tape format.  When cassettes were first introduced, they
sounded fair at best, speech being the only range that these new
recorders could handle even moderately well.  15 years later, things
have changed and the Nakamichi Dragon is considered excellent in
storing the sonic information of an analog disc.  Quite an improvement!

Now, the digital CD format is the new contender.  Although the sound
is getting better (new filter designs, improved error correction
schemes, etc.), CDs are still inferior to state of the art
analog sound TODAY.  This is the only issue that the people at
SHEFFIELD are making; of course they have a vested interest, but
their philosophy at SHEFFIELD is to make the best reproduction as
humanly possible regardless of recording format.  The day that digital
recorders and playback systems become superior to analog, SHEFFIELD
will most likely buy a state-of-the-art digital system and gear up to
that.  It's not that they're anti-digital, but rather pro-quality.

I would like to dispute some of the
comments made in the article, namely:

-CD recordings are inferior to the
 best analog recordings

-The CD is facing the same teething
 problems as the cassette.

While I must admit that there are a lot
of BAD CD's out there, I don agree that
Digital Disks in their present form are
inferior:  many of the problems 
associated with bad CD's can be traced
to producers who press CD's as if they
were vinyl.  i.e. they leave the treble
boosted (to offset vinyl losses),
leading to screechy treble, and/or
sum the bass (to avoid overcutting the
vinyl), etc., etc.  A state-of-the-art
CD pressing, Telarc for example, beats
*ANY* vinyl hands down.  

The second point:  while CD's may not
be perfect right now, it is facing 
opposition that never faced the Compact
Cassette.  When the cassette was 
introduced, tape recording had been 
around for a long time:  it was a 
familiar technology.  What the CD is
facing is opposition from people who
can't or won't accept that music can
be "chopped up" and then restored.
A fundamental stumbling block must be
overcome before CD's become as 
"intuitively natural" as the analog
recording process.

I think that the CD is a great step
forward:  one that *ALREADY* super-
cedes vinyl.

WEll, Phil, since we're moving out of the realm of physical
<and here I include perceptual)  fact and into the realm
of unjustified opinion,  (in other words, we're starting to
talk like Doug Sax) let's move to net.flame.

Your comments just don't take account of the research that
has gone into digital methods of recording.  <The analog disc
was perfected ON the market, the digital disc was essentially
designed completely before hitting the market.  Furthermore,
the techniques used on the digital disc are neither new nor
untested, they are merely new to the CONSUMER market. 

The digital signal processing community have been using the
same techniques as CD's for (in some cases) up to 20 years.


See you in net.flame
