Hello!
I am interested in buing a walkman. Last time that
I wanted to do that (a year or more ago), I thought 
that all walkmans that I tested seemed to
playback my test tape slower than the home CD and
tape deck. I don't think I just imagined things,
because I actually used a stopwatch (even though
I did that on one song only). Perhaps batteries
were the cause for that, but the salespeople said
the batteries were fresh.
Anyways.

Can anyone suggest a walkman that will playback 
at the same speed as a home machine?
I am not interested in expensive walkmans, and
they should also be able to survive jogging.

Any help will be appreciated.

Thank you

Christos

Well, I didn't want to say anything, but it IS a general characteristic
of net news that if someone asks a question, and no-one wants to answer
it, it's often helpful to put in a wrong answer.  There are a lot of
people who know the answers who are quicker to correct a wrong one than
to put in the answer in the first place.

(In fairness, I suspect that a lot of them think along lines of 'gosh,
everyone must know this, so I don't need to bother with it because 5000
other people will answer it anyway'.  So it may serve the useful
purpose of keeping traffic at a readable level.  And, it does sound
like pretty reasonable reasoning to me.)

Bzzzzzt.   If you have a 20Hz-20 khz bandwidth,anda 20kHz periodic signal,
what do you see in the spectrum after you filter out the part above
20kHz?

The fact you believe it's irrelevant is a clue in and of itself that
you need to study the basics of fourier analysis before you continue
on this thread.

Huh?   Perhaps you also need to study the basics of quantization and
PCM coding.

I'd suggest Taub and Schilling for the fourier analysis (simpler
than most) and Jayant and Noll for quantization.

the Radio Shack unit is a fully licensed Dolby Surround Sound decoder.
it has the Dolby double-D symbol on the front of the processor. it's
only a 3-channel decoder (no Pro-Logic), a fixed delay of 20ms, 3 inputs,
a line-out, a front-out, 10 watts per channel for front and rear speakers,
or 20 watts per channel in rear-only mode (your stereo provides the front
speaker power). there's a tone control, front/rear balance, input balance,
left/right balance and a volume knob. no remote (unfortunately).

the unit i have has served me very well for the past 1.5 years. i'll 
eventually be upgrading to a new receiver/amp and will definitely get
a Pro-Logic setup, but the Radio-Shack unit works quite nicely as a 
bare-bones, get ya started, sort of Dolby Surround Sound Decoder.

	Which one should I buy? What are the pros and cons of each

	I have also look for a CD player but I don't know what to look
for to compare the different models. Do I need to buy a good quality
one ( 400$ CAN and more) or is the SONY CD player (200-300$ CAN) are
good enough? What type of feature do a CD player need to have ?

Has anyone ever compared some of those high end "mini systems" (eg.
the Sony MHC 3600, Panasonic SC-CH10, Kenwood UD-70, etc) to a sort of
low end component system of similar setup ($1000 gets speakers,
receiver, CD player)? What I'm asking about is sound quality, since
obviously, the expandability of the mini system is quite limited. I've
listened to the models above quite extensively, but I'm quite clueless
about anything else. Opinions, anybody?

Pardon me?  "only a certain type"?  Distortion results when the
device isn't linear. ANY deviation from linearity is noise,
signal correlated or not, ergo SNR DOES measure ALL distortion.

Of course, it doesn't MEAN much, but it DOES measure all distortion.

As to your other "information", it's "Inter ModulATION distortion"
and it's got to occur in ANY device having ThD type distortion.
BOTH are reflected directly in SNR.

I've heard this said, too, but Klipsch claim that the K-horns have extra-
ordinarily flat response compared to other speakers. Indeed, their literature
shows a response curve which is flat to within two dB from below 20Hz to above
20KHz. Do you or anyone else have any data or references to support the
statement that the K-horns suffer from any coloration at all? Or should we
suspect the Klipsch literature of being unreliable in this regard?

I've heard the Martin-Logan CLS 2's and did not like them. They
sounded too light-weight, and the bass was not good enough.
Stereophile seems to like their high end, and goes gaga over their
combination with a subwoofer system (Kinergetics?). 

I have a friend who chose the Magnepan 3.3R over the Martin-Logan. I
listened to the Apogee Duetta (around $6,000), and they do sound good.
The new Apogee ribbon/dynamic hybrid line (Centaur) might be worth a
listen. In general, I personally would prefer dynamics. My overall
impression is that electrostatic or ribbon speakers are very difficult
to place, and do not sound very dynamic (life-like).

I'm not an elec engineer but here is a try.  Electronics mostly
operates off (low voltage) DC supply.  The first thing which happens
inside the appliance is a transformer and a rectifier which converts
110 V AC into something like 9 V DC.  So if you put a 240V --> 120V
transformer between the wall and your appliance it should not matter.

The only possible catch is equipment which uses the AC frequency to
drive some motor.  Now the AC frequency is $\pm$ 2-3% so that it's no
good anytime the slightest precision is desired.  (E.g. it's ok for a
wall fan).  I find it hard to imagine anything in a music system which
would use a the AC frequency for anything.  If there is please tell me!

In short: I think you can take any audio equipment, computer, etc. from
110 V to 240 V and not care for the different frequency.

One data point: my sister is using a CD player through a 240->110 transformer.
It works just fine.

        -ans.

Again, we are basing what is CORRECT as what measures best.  Not only that,
you use people who spend more time in the orchestra than listening to the
orchestra as those who know best what the orchestra sounds like.  My opinion
about most musicians, not all, have a fairly poorly developed taste in
sound quality. There are exceptions. Most musicians, classical ones, don't
get interested in stereo, mono will do.  It's not what they're in tune to.
They listen to performances, not room clues and quality of timbre.  They are  
usually on the bottom rung when it comes to being a listener, they are players.
I think what is being implied here is off base.  We are to assume musicians
know sound quality best?  Not even conductors.  Try recording engineers, the
few who care.

> Now, what does this say about analogue vs digital sound?

It says there will be forever people who like one over the other. So what?

> Or such devices as the Wadia DACs, which roll off the treble by 5dB at 20kHz?

It doesn't say a damn thing to me. 

About the audiophiles who attended their first concert:
Some audiophiles left because it doesn't sound right.  That's 
the problem with some audiophiles -- their reference is at home and in their
head.  But it doesn't really diminish their enjoyment just because live 
is a disappointment to them.  Live has acoustic problems homes don't have,
and what seat you get greatly changes things.  Also, live has obnoxious
coughers, louder and more annoying than clicks and pops.  Audiophiles 
are used to panoramic soundstages, they may have got a back row seat where
the sound was muddy with reverb and floors shaking and sounding too "blended."

I've been to many live concerts.  The best seats are back a little so the
orchestra is viewed down below (not up above).  The sound is always better
live to me, but I may not like their program.  And my musician father and
my friend who plays second seat at the local symphony both own 1970's 
stereos and they both think they sound great.  But play them a note slightly
out of tune and they both jump on you for it.  Different mode of operation.

For the most gain in the min. space (at least for a reasonable first-time
