Rise and fall times have to do with TRANSISTORS, NOT CABLES!!!!

If you stay within the specs of the respective lan's topology, you
should be getting error-free transmissions 99.99999% of the time. Collisions
are another story, and aren't effected by cabling (I have installed my
fair share of LANs).

That's what specs are about.

In this case, we were refering to a 1meter long coax cable.  There is
nothing short of an EF-111 (electronic countermeasures aircraft) in
the garage that going to screw up bits on a coax at less than 1megabits
per second (which CD is).

They use exactly the same tape as in their 90 minute, only longer. Am I

I am in the market for a pair of B&W Matrix 803 or 804 or 805`s.

I am leaning more towards the 804 or 805, but I would consider
a 803 if the price was right.

I would like the speakers to be as close to perfect shape as 
possible, and I will only do COD orders.  NO CASH transactions.


If there are anyone out there who would like to make me an offer,

Article-I.D.: andrew.8fI7bQ600iUOMvQ71r
Organization: Systems Group 98, Carnegie Mellon, Pittsburgh, PA

I'm looking into the purchase of an a/v receiver for my "home theater"
system. My minimum requirements are:
	Dolby ProLogic
	S-Video: 2 in/out
	Audio: 4 in/ 2 out
	Video: 4 in/ 3out

If it matters, a satellite receiver, svhs vcr, and a 27" tv are in the
system. Laserdisc isn't important at this time but I want to leave
that option open. The "main" speakers will be the speakers from the
current receiver, for now, and I haven't decided on center/surround
speakers yet (though I'm leaning towards Cambridge Sound Works, for no
good reason other than simplicity).

After digging through the various magazines lying around my house, I
found the following receivers:
	Pioneer VSX-D901S
	Pioneer Elite VSX-95
	JVC RX-905V
	JVC RX-1050VTN
	Onkyo TX-SV909Pro

Would anyone care to comment on any of the recievers? Any others that
I should be looking at? Am I missing any important factors?

I don't want to be too demanding, but specific likes and dislikes
would be prefered over "yeah, I like it." :-)

I'll summarize any replies.

Thanks,

Walter

One interesting test is the passage "Why Hi-Fi Experts Disagree", written and
read by J. Gordon Holt, on the first _Stereophile_ Test CD.  They switch mics 
every paragraph or so.  The "liner notes" identify each mic and add some 
comments.  I have no idea what JGH sounds like in person, so I don't know 
which one sounds closest to right.... but the variation between mics is not
subtle, even among models that are often used for mastering voice.

It gets more bizarre than that!  I just got the latest J&R Music World 
catalog.  Prominently featured in the front pages:

	Sony MZ-1	portable MD recorder/player	$700
	Sony MZ-2P 	portable MD player		$500
	Technics RS-DC10 home DCC deck (rec/play)	"call for latest price"
							(don'cha just hate 
							that?)

Now for the kicker:  On the last "new technology" page we find pre-recorded
MDs and DCCs.  $14 each.

A few pages further on are lots and lots of CDs.  Many CDs go for $11.  A few
are $14.  A *very* few are more than that for single CDs.  The vast majority
are from $11 through $13. 

A few spot-checks against an older catalog show that CD prices haven't gone
up.  

I've said it before and I'll say it again:  MD and DCC both deserve to lose.
Encourage your friends to NOT buy into these new technologies.  If they
complain that CDs are too expensive, point them at shops that carry used CDs.

(Some of the stores of some of the big chains like Tower are starting to do
this!  Encourage this wherever you can!  The record companies aren't happy
about it.  Hah!  Serves 'em right for trying to charge over $15 list for an
item that costs under a buck to produce.)

This is rec.audio endless argument #27.
You're right -- single blind is completely nonscientific and your
results prove nothing. I have read descriptions of several double-blind,
controlled listening tests of CD players. They have found either:
1. No detectable differences.
2. Tiny differences detectable by some listeners with certain material
   (the most reliable detection of differences occurs only with test
   tones; most "golden ears" listeners could not detect the differences
   between any two CD players on any musical material). When differences
   were detectable, different listeners disagreed
   about which was "better" (many couldn't even say which was better, only
   that the two sounds were somehow slightly different); all agreed the 
   differences were small.

The differences detected in such tests (when they have been detected)
are smaller than the proven "differences" detected in:
1. Double-blind comparisons of a component with itself, with levels
   mismatched by 1dB or less. Such level differences are clearly
   heard, but not as differences in level; they sound like differences
   in sound quality.
2. Tests in which people are told they are listening to two different
   components, when in fact it's the same component. 

I admit I've only read a tiny percentage of the literature on the subject,
but until someone presents evidence otherwise, I suggest that unless
you have performed a double-blind ABX test with levels matched to less
than .1dB, your "evidence" is worthless. The studies I've read strongly
suggest that you would make far more difference in the sound of your
system by moving your speakers 6 inches in any direction than by changing
your CD player.

Ok, so tell me.  It's a transient, so how can it have
harmonics?

A transient has a continuous spectrum.  A PERIODIC signal
can have "harmonics".

Subject: DB meter problems on Teac Recorder
Date: 5 Jan 93 18:42:17 GMT
Organization: TWICS, Tokyo, Japan

I have a TEAC V8000S--don't know if this is sold in the
US market, but it is based on their recent series (3000, 5000,
7000.  The 8000S is 7000 plus DOLBY S).

My question may be general enough to be answerable by anyone,
so let me try.

#1 may or may not be a problem.  DB Peak level meter readings
differ on source and tape monitor.  Seems to be normal if I check
my older decks' VU meters--record is always at a lower level.  A
differnce is that playback DB level depends on output level, which is
fixed on this deck but not fixed on my older TEACs (4 channel reel
deck and old two head model).
    Question is, do I set record levels for what the DB meters say
on record pause (source monitor) or do I sent them on off-tape
readings.  FOr example, depending on the tape they have an ideal
record level of plus X decibles.  But if I aim for that in setting
the meter off of record/pause, they are belwo that on actual recording.

#2 concerns a second reading..they have a peak margin display at the
bottom of the peak level meter...it goes into OVER mode if over
12 DB...but the number displayed is ALWAYS higher than where the
meter indicates...example; meter on SOURCE says 8 and margin says 4,
the same on tape --meter says 4 and margin says 1....

is there a difference in the function of these---I thought the
bottom MARGIN meter was just a numerical representation of
what the peak level meter reaches (and the peak level meter
is more general..But here the peak level meter has a higher number!

#3  concerns CD level check.  In off mode, yoiu push this and spin a CD
at high speed to monitor the highest levels.  This easily goes
into over unless I turn the record volume down.  But on checking the
levels reacjhed with SOURCE/TAPE readings, now they are too low.
So the CD level check gives me a false warning and I overcompensate.

For example, comparethe difference....

CD  CHECK             TAPE            SOURCE


meter 10
margin 12            meter 0.5         meter 1.5




meter 10
margin 10             meter   6        meter   8
                      margin 3         margin 4


#4 is relatefd to 3....I was using a test tone (from my old 
digital keyboard keyboard to tape of all things) .  Even if
I use a CD, I still get the same results whether played fast or slow.
At first I thought there was volume compnestaioon to account for
CDs palyed fast, but fast or slow, the resulting levels are too high.
Are these features worthless, am I misunderstanding them, or is there
a defect?

Thanks.

the individual.  Please respond in UNEWS.  In return, if anyone
has any questions I can research in the audio shops or with the

Absolutely correct. I usually use the phrase "bandwidth and bandwidth
anomolies" to cover all bases. The last time I did that, one person jumped
down my throat for deliberately using a vague statement (which was
precisely my intent), and 5 million others wanted an immediate lesson in
whatever it was I was talking about.

You may try your local high end stereo stores. Several of our local

I am considering purchasing a pair of Bose 601's Series II speakers second hand
The pair that I have identified are about ten years old and have been in dry,
heated storage for approximately seven years of their life.  They seem to be
in excellent condition and don't seem to have been abused at all.  I have heard
that the quality of earlier Bose speakers are often times better than what they
make now.  In light of the new retail price being around $1,000, their age, 
and condition, is it reasonable for the seller to be asking $450 for them.  If
not what would be a reasonable price for these speakers?

Perhaps I wasn't clear.  I didn't mean to say that digital filters can correct
an aliasing problem that has already occurred.  I was trying to talk about
the "oversampling" function of a CD player and its role in reconstructing
analog from a properly sampled digital signal.  The interpolation of samples
to raise the sampling rate can be thought of as a filtering operation that
is accomplished in the digital domain and relaxes the constraints on the analog
part of the reconstruction filter.
