Sure, the power supply has a bearing; without it the CD player does not
work :). But you are not going to find sonic differences between $5K and
$500 or less players due to power supply; all the mass manufacturer's CD
players I have read reviews on have no trouble keeping line spurs out of
the signal.

On the other hand, maybe there is something in what you said. There may
be boutique players with really poor supply regulations. :) The high-end
designers are fully capable of screwing up a power supply design!

Oh, and how did you figure out that the power supply in a CD player
affects how it presents "upper bass and midrange"? I would have guessed
that the results of a poor supply would have been hum and increased
jitter. Or worse high frequency response.

OK, that is your $5000 player. What about the $500 one?

However if a $20 CDP sounds worse than a Benchmark for $900, then it
logically follows that there is possible differentiation between players and
not everything is SOTA which was my point.

I would go further and say a "$500 CDP" that being unspecified and
unidentified could very well be far worse than a "$5000 CDP." Since we are
talking hypothetically.

Given the way the brain works - that is not always a bad metric, but I agree
that it can be very elusive to pin down.

But, OTOH it also difficult to pi9n down what a "$500 CDP" might be and what
a "$5000 CDP" since some are very well engineered and some not so well....

Sure I do - the particular reviewer that performed the review was amazed
that an amp that measured so poorly sounded as good as it did.

Dunno - I have a pair of Klipsch [albeit low end $200/pr] and they seem
rather bright and congested in the mid range. They really do sound good for
the money, though.

OTOH, since you have *never* presented any reliable and repeatable
evidence that you can actually hear these claimed 'differences',
perhaps you should limit youreself to suggesting that such things
*may* cause a slight *theoretical* improvement.

My basic problem is I believe the blind testing itself knocks out many
significant "ways" of hearing beyond just sight, and none of the arguments
here have convinced me otherwise. Until the testing is verified not to
interfere with open-ended evaluation of differences, and until the
"disappearing" is investigated in more depth than it has been, I and others
will continue to trust our basic instincts.

You didn't expect start an argument, but you wanted to see if anyone
thinks there's a difference so you can tell them they're wrong?

I think my Arcam CD23 FMJ sounds better than my AMC CD8b, although I
ascribe the difference to design, not to magic or "more money." Am I
wrong?

Several years ago I conducted a test which the participants believed
to be sighted. They all heard the differences quite distinctly every
time, and had no problem at all identifying the two components under
test.

The only problem was that the cables I was changing were not in fact
the ones carrying the signal. The real cables remained unchanged
throughout the test.

So without the pressure of blind testing, the participants were all
relaxed enough to hear the differences easily. Shame really that there
were no differences to hear.

This is why blind testing really works, and why the results it gives
can be trusted.

I guess the concept of diminishing return does not work for you. Your
logic fails because there is a minimum cost to doing things right, like
when it comes to making a CD player with no errors detectible through
normal listening. We have been arguing that the minimum price for such
players is below $500, and no one has said that the price is $20 yet. We
are not saying that the $20 will sound as good as a $500 player, because
below a certain price point, some corners have to be cut that might
affect sound.

On the other hand, going above $500 rarely will buy you anything
improvement in sound. You might get some different sounding players, but
chances are they are less accurate.

Given the way the brain works, that is a terrible metric!

Do you believe that people have the same memory of live music,
regardless of the kind of music, where they sat, or how long ago they
had listened to live music? What about people who have never been at a
recording studio, how are they to know what a studio recording should
sound? What does accuracy mean for different people then? How does the
designer design to that elusive, highly personal, accuracy of memory?

Do you want to design a circuit with no objectively measureable specs?

But that is very different than what you said previously, that $5000
will *necessarily* buy you a better player, no?

Some of us are saying that the mass-manufactured players such as those
from Sony selling for less than $500 are more likely to be consistently
good in terms of accuracy.

Actually there were two reviewers. I am not sure if the one (Mr.
Atkinson) who made the measurements ever said that the unit sounded
good. And the one who wrote the purple prose appeared to not worry about
measurements at all.

The point is that inaccuracy, in a non-blind listening session where the
price-tag is known, might appear as excellent sounding for some golden-ears.

Actually, lots of them, just not here. Other discussion sites, which
get a lot more traffic than this one (audiogon, audioasylum) are
dominated by people who believe that literally everything makes an
audible difference (and that they are special because they can hear
these differences). Those sites also exercise censorship to keep down
opposing viewpoints.

After all, if there weren't consumers willing to believe that $5,000 CD
players are better, there would be no $5,000 CD players.

Ah, but that's what most people who buy those magazines want to read.
Atkinson and Pearson would starve if they tried to satisfy the likes of
you!

You might be. What part of the latter's design do you think is subpar,
and how do you know that it is sufficiently subpar to be audible?

And while we're at it, how do you know you aren't just imaging a
difference between them? Happens all the time.

Over the years I have wasted a lot of money. I have two Marantz CD
players - a 63SE and a 67SE. I added a MSB link D/A converter with a
special power supply, a DIP jitter buster and use Kimber PBJ cables. It
doesn't matter which I listen to or whether or not I go through the
outboard converter. Everything sounds the same. The cables don't make
any difference either.

I have two pairs, a pair of $1,200 Synergy towers with built in subs
and a set of Reference Series RF-7s. Both are "crisp" but not painfully
bright, which is where I find the Infinity product to be, and neither
are congested anywhere in the line. In fact, I quite like their sound,
they have a nicely defined high end sound with solid mids. Mated with a
powerful amp and a good sub, I've found very little else, at least at
that price point, that sounds as good. But I am partial to Dynaudio's
towers, which start at about $1,500 a pair and move up to almost $80k a
pair.

Umm...no. I wanted to see if anyone could actually deny the reality of

The "I thought I heard it, so it's there" rhetoric is faulty.

But this is an irrelevant comparison, because you are only comparing
the *transports* in these players, not the whole player. It is in fact
likely that if you take a dozen CD players ranging from $100 to
$10,000, they will all use one of the same two transport mechs
(Philips or Sony), and will all sound identical. This ain't rocket
science!

More like $10,000, but whatever.

Why mess about with a mere CD player at that price? Go for the Pioneer
'universal' DV-565, and get great sound from almost any variety of
silver disc - plus all the films you can watch! If you insist on a
'pure' CD player, then the Arcam CD-73 is probably as good as it gets
technically.

I believe they have two basic transport mechs, I don't know if both

You first have to show that the $20 player does in fact sound worse
than the Benchmark.

I would say that it's *much* more likely that the $5,000 player will
have poor performance!
