If it sounds better to you, great.  The claims made for it seem to
contradict what's known about how the human ear works, though, so I'm
skeptical.  I also know there are a lot of tricks they can do to make it
*seem* to sound better -- one easy one is to make the output level from the
player slightly higher when playing SACDs instead of regular discs.  People
will perceive the slightly louder music as "clearer".  Tinkering with the
mix is, as you mentioned, another option.

If I remember right, they're encoded at 24 bits instead of the 16 on a
regular CD, and at a 2.4 MHz sample rate instead of 44.1 kHz.  Note that
44.1 kHz is enough to accurately record any sound up to just under the
Nyquist limit of 22,050 Hz, and the human ear can only hear up to 20,000 Hz. 
Also, 16 bits is thought to have about 3 dB more dynamic range than the
human ear can actually pick out in music.  Hence my skepticism.

Mostly this is being pushed by record companies.  When CDs came out they
were able to sell everyone new copies of all the albums they'd previously
bought on LP -- profit with no expenditure on promotion or finding
new talent.  They're hoping to cash in on that again by getting everyone to
upgrade to SACD.

re: 51 / 53

That's something I've been confused by. I distinctly recall CD's being touted
as "perfect", in that they're able to reproduce the entire range of listenable
music. IIRC, the *only* limitation of CD's is the masters they're recorded
from. (Does anyone else remember the AAD/ADD/DDD specifications that used to
be printed on CD's?)

This is the same reason I don't entirely understand how a $2,000 "reference"
CD player can produce notably better sound than a $60 CD-changer. I mean, it's
just a digital stream. You can't really convert it in different ways. Yes,
I understand that the mechanism that turns that stream in to something my
receiver understands can be of varying quality. It's the reason my 200-disc
changer is connected with a fiberoptic cable, instead of two RCA cables. But
there's only so much improvement you can build atop the core technology.
Certainly not $1,940 worth.

In terms of pure technology and understanding of human hearing, I don't see
how it's possible for SACD (or DVD-Audio) to sound better than a CD, except
under very rare circumstances where the music pushes just beyond what a CD
is capable of. But for whatever reason, it does. There is a presence in
non-vocal music on SACD that isn't quite the same on CD. It seems more
lifelike, although I can't figure out how it possibly can be, other than
tinkering with the mastering of the disc.

Although I'm not yet willing to buy in to a Sony/Philips/RIAA consipracy, I've
always believed that mass-produced CD's haven't been mastered to their fullest
potential since the CD format gained complete consumer acceptance. It seems
noticably coincidental to me that an artist's debut album sounds (in terms
of clarity) better than following albums more often than not. Conspiracy?
Probably not. Laziness? Absolutely. Why spend days mastering, and remastering
something that you already know people are going to buy either way?

With SACD's (and formerly, CD's) there was a degree of uncertainty there. They
cost more than other formats, weren't as versatile in terms of being copyable
and/or playable in cars or portable units, and the players cost more money
than most people spend on components.

Writing this made me remember something...so I just tested my theory. Janet
Jackson's "Rhythm Nation" sounds very, VERY crisp and clear, despite the fact
that it's an AAD master from 1989. The same song ("Alright") sounds muddier
(albeit, slightly) on "Design Of A Decade" which was produced in 1995.

In 1989, you were lucky to pick up a component CD player for less than $150.
Portable and integrated CD systems were much more expensive (and prohibitively
so, for the teen audience that record companies target), and there wasn't
exactly a slew of CD's to be bought. In 1995, you could get a nice integrated
portable system, or disc changer for half of that price, and there were tons
of CD's available. Most anyone who wanted a CD player could afford one, and
because of that, there was no real need to convince anyone of the clarity that
CD's provided, because you could sell them on the convenience factor.

Whether the laziness was slowly accepted as cost-effective, or planned all
along is probably unknowable. Or maybe I've just been listening to CD's for
so long, that I associate older discs with how amazingly clear they seemed
to be. I dunno.

Well, there are a couple things "wrong" with "perfect" 16-bit 44MHz CDs.

One thing a few audiophiles have claimed is that human hearing doesn't stop
at 20KHz, and even if it does there are phasing artifacts well above that.
So, some people doggedly hang onto their vinyl since it doesn't have that
fixed 22KHz theoretical limit.

The issue about CD players is that while the digital stream always decodes
the same, not all D-A converters are created equal.  The cheaper units tend
to suffer more from noise from other parts of the circuitry, nonlinear effects
from the semiconductors, and non-optimum analog circuitry.  

That being said, my hearning is better than most people's and I can't hear
any limitations.

Higher-end CD players tend to have better tracking subsystems, too.  My
1986-vintage Sanyo player, which was probably pretty expensive new, will
play discs that my Discman gives up on, and it skips less often.  This may
have something to do with the fact that the Sanyo splits the laser into
three beams for tracking purposes, while the Discman multiplexes a single
one.

There's also some room for tweaking in the analog filters that have to
follow the D/A converters.

Filters that affect the passband.  Power supply design.  Stable clock.

I'm not saying it's worth an extra $2k, but there is more than one way
to skin a cat, and my $600 player does sound better than my $60 player.

I have to agree though that the record compaines are in the business to make
money and sell you more formats.  That said, SACD and DVD-A are improvements.
IS it worth it to most people?  Doubtful.

CD's:
If you're into any type of music that doesn't have a pretty compressed
dynamic range (classical vs. pop for example), the 16-bit CD's ability
to make *both* the really quiet parts (like some wind instrument solos)
and the really loud parts sound good is pretty limited.  I've certainly
experienced this (though i can't rule out that it's just poor quality
production work).
My understanding is that there's plenty of room for a niche market
selling the same music on the same media, but with all the slip-ups/
short-cuts/etc. in the production work corrected.  Some perfectionists
have money. 
Younger people often have hearing that goes up to 23+KHz.  CD's and CD
players have to fade out quite a ways below that to avoid wierd effects
from their 22KHz limit.  
Even if the digital music on the CD is "perfect", it's technically 
impossible to convert that to an analog signal with 0% error.  More
money can buy you less error...how much you got and what's good enough?

response 61 of 104: Mark Unseen   Aug 26 03:32 UTC 2002

I think that's bordering on pretentious. 

Yes, any D/A conversion is going to have some degree of error, but we're
not comparing something with a 10% error rate to a 1% error rate. We're closer
to 0.73% vs. 0.03%.

I used to be able to hear the ultrasonic motion detectors in Fiegel's,
but I didn't have anything resembling good musical taste at the time.

I don't know how well the music industry is going to be able to force
the genie back into the bottle.  CD is more than good enough for most
people, and huge numbers find MP3 acceptable.  SACD may be an
improvement, but I doubt that very many people will care enough to want
to replace their legacy CD players and collections.  As long as people
want to play their old CDs, even SACD players will have to support the
format; that will make all the watermarking in the world useless.

Hardcore audiophiles also buy special oxygen-free speaker cables that
cost $20/foot, and think resistors wound with silver wire sound better
than ones wound with nichrome.

  re #63:  bought a recording on LP or cassette tape lately?

           once a clear winner emerges from the battle between
           new "secure" digital formats, expect the record companies
           to start cutting back on which parts of the catalog they
           release on CD.  that won't compel CD owners to upgrade
           their existing collections, but it will force much of the
           market towards the new format.

An article talking about how the RIAA is continuing to blame file
sharing for the drop in CD sales.  It rather sarcastically suggests
several alternative reasons.

http://www.theregus.com/content/6/26099.html

'"Though other factors like the decline in consumer spending have played
a role, Cary Sherman, President of the RIAA, said that illegal music
downloading was the main culprit in the drop in sales," the lobbying
group explains.'

'Clearly the RIAA knows its enemy, and has the numbers to "prove" it. We
just wonder who they'll blame if they ever achieve their
government-mandated DRM copyright paradise, and sales continue to
disappoint.'

Thompson Multimedia has changed their MP3 licensing policy in a way that
makes it GPL unfriendly.  Apparently it's still free if you're producing a
free application, but royalties are due if the application is sold.  Or so
they say; they've removed the old language that exempted free players
entirely, so there's no longer any official assurance they won't exercise
their patents against free applications.

The New York Times has an article on the commercial launch of the 
teensy tiny DataPlay discs, which we've discussed here before.
The article is not too optimistic about the DataPlay's chances 
for wide adoption for music; at best, says one analyst, it may end 
up a marginal product like the MiniDisc.   The music industry wants
the product to succeed because it includes copy prevention features.
 
There is a nice picture of the DataPlay disc next to a CD.
