I have ordered from J&R Music World for 10 years. I've ordered
CD players, tape decks, receivers, speakers, word processors,
car stereos, actually quite a bit now that I think of it.
Everything has always been completely satisfactory, and I would
not hesitate to order from them again.

I do have one caveat, however. I have noticed that in the last
couple of years their quoted prices have gone up, to the point that
often I can beat their price locally. The first time I pointed this out
they immediately lowered their price, and I ended up offering an
even lower price which they accepted. Since then I have had
to barter on every order, and have gotten prices lowered by
10% - 20%, pretty substantial discount from their initial
telephone quote. The sales force is on commission, and my
impression is there is a minimum allowed selling price and if
an item is sold above that price the salesman increases his
commission. If he thinks you are going to hang up without a
sale, he will reduce the price since he has already spent time
on the phone with you and some commission is better than no
commission. I don't care for this practice, but I order from
J&R anyway because I can usually get my price, and other than
that J&R is first class in every way.

Their phone number is 1-800-221-8180.

I think the sampling frequency must be twice the BANDWIDTH of the signal
you're trying to sample.  Of course, Nyquist never said it would be easy.

I believe Firesign Theatre also had a comedy album in the mid-70's with
dual grooves on one side.  I also recall a home horse-racing betting
game which had a record with around a dozen different grooves on each
side, so that you'd could drop the needle and get a random audio coverage
of a race with different winners on each groove.

I had requested information/advice on choosing a receiver earlier also. I
haven't seen much reviews about Kenwood receivers and hence would appreciate
if someone could post it on the net. I was going through the features of
KR-V7040, KR-V8040, KR-V8540 and KR-V9030 in a catalog (I think Crutchfield.)
and their quotes.(which seemed a bit higher then other mail order places).

In the March issue of Consumer Reports, KR-V7030 was rated as a best buy. How
reliable are Consumer Reports anyway ? That particular issue also rated 
Onkyo's TX-906 as a good buy in the Dolby Surround category. TX-906 
isn't a powered Pro-logic receiver although it has the required circuitry.

Thanks in advance for the help.

And even before that, they quit making acoustic phonographs and recording
acoustically, and put in those electronic microphones and amplifiers and
cutting heads and pickups and loudspeakers, distorting the music with an
"electronic" coloration.  And even before that they obsoleted our cylinder
recordings (each one an original!) and substituted flat records that could

  my dolby pro-logic receiver doesn't have a separate amp for the center channel, just
the pre-amp output (which it puts out L and R, kinda strange since it should be only
be one channel).  so i have two options:
     buy a separate amp - 
            can i get an amp under $100 for this purpose to drive an 8-ohm speaker.

     buy a car audio amp -
            these are fairly inexpensive for the ones around 40 W.  is it possible to hook
 	    up a standard DC power supply (that can deliver the neccessary power) and have
	    it drive an 8-ohm speaker.

thanks for any tips.

   cd is approx.2*44.1Khz*16bits+a couple of percent for other signaling +
   directories

times about 75 minutes, of course.  

 2 channels * 44100 samples/second * 16 bits/sample * 75 minutes * 60 seconds/minute

is 6,350,400,000 bits or 396.9 megabytes. (80 minutes takes about 423M.)  A
CD-ROM in ISO standard format can hold nearly 700 megabytes.  I suspect a
significant amount of the "missing" space is for the error correcting code's
extra bits.  The Audio Engineering Society (212) 661-2355 would be happy to
sell you the complete specs (including pressing tolerances, which is how these
very long CDs are squeezed in) for $4.

Keywords: AR CD-04

A friend has just offered me his Acoustic Research CD-04 CD player. The new
price about 3 years ago, he says, was NZ$800 (about US$400), and he's
asking NZ$300 (about US$150). The LEDs on the front had stopped working,
but he's going to get them fixed first.

I haven't yet compared it to other players---that's a task for this
weekend---but I was wondering whether any of you had any comments. Is this
a good player, one to avoid, or somewhere in between? What's the price
like? How much have CD players improved in the last three years? (I'm a CD
novice, owning 6 discs and no player at the moment.)

Post or email; I'll summarise if anyone's interested.

Thanks,

I have heard a friend's Cyrus speakers (I think the model number is
761) a couple of times and am very impressed (on a Marantz integrated
amp.)  Smooth mids with an amazingly solid and deep bass for their
size. Made me quite envious.  Certainly worth hearing.

One more thing on the A1 amplifier. I had real problems with the
volume pot on mine. I used to leave the amp on a lot, and it idled
very hot (as expected from class A equipment.) The pot eventually got
so noisy that just touching it would cut the left channel in at full
volume. I gave up on cleaning it every few days and traded the amp in.

I beg your pardon?  A sine wave has ZERO bandwidth if it lasts for
all time, and very, very small bandwidth if it lasts for, say,
a few seconds.

Given that, a proper coding of a sinewave can proceed at a VERY, VERY,
VERY low sampling rate.  Now, yes, one has to THINK how to do it,
and has to do some very intellegent filter design and decimation/interpolation
work in order to do this, and sine-waves are easier generated than
transmitted in most cases, BUT a sine wave of 20kHz, with no other
signal every possible, does NOT require at least a 40 kHz sampling
rate.

	UGH!!!

  In my opinion, mini systems are for those who think sounds coming through
a styrofoam cup with a string attached are Ok.

  I know somebody who spent $500 on one of those mini system.  Sounds great
if your listening room is a closet or the equivalent.  It sounds decent at 
low volume, but it is hopeless at a higher volume.  These things are only
around 20 watts.

  If your listening area is small, spend $300 for something like a pair of
Bose 301 and the rest on a decent amplifier, tape deck, and CD player.
Put all these together, you got something that gives you as much functions
as those mini systems while sounding a whole lot better.  In addition, it's
upgradable.

  Just a thought, the $500 mini system my friend got won't let you control 
the recording level or balance when recording to a tape.  But it has one of
these nifty button that at one touch you can record an entire content of
a CD to a tape.  USELESS!!
