I picked up a Sony X55ES for about $500 as a floor sample (Q Audio in 
Cambridge, MA). The X55ES was Sony's ultimate single box ES cd player 
(there were one or two higher-end models, but they were basically this
transport plus an external DAC), and sold for about $1000+. It has the best
CD sound I've ever heard, partly coming from the fact that it is ultra-stable
(weighs 29 lbs!!!). If you look around, you may be able to find one for $500
or so. Sony discontinued the X55 at their last line changeover (even their
ES line changes over every year or so), and apparently didn't replace it
with anything comparably high-end.

>What about near-new, unscratched CDs which skip?

I have an old el-cheapo technics CD player that occasionally has
skipping problems.  The problem is NOT the disks, but the player.
The laser assembly is on a "sled" that slides on two lubricated
rails.  After a while, the grease gets all pushed to the ends of
the rails and then the sled will stick, thus causing skipping.  


To solve the problem, I just pop the cover, redistribute the
grease and slide the sled back and forth a few times.  After
that, I have flawless performance for another several months.  I
also take the opportunity to clean all the dust and peanut butter
off the laser lens.  It's cheaper and more effective than those
little "cleaner disks".

My car has Alpine unit with radio/tape + CD controls.

One of colleagues is selling this piece. I appreciate if you can tell
me whether you recommend it or not. The price is about $150

Description:

  exisiting AM/FM cassette head unit (CD changer has RCA line out),
  user manual and installation guide included.
  Good working condition.

I have heard multiple generations of psychoacoustically coded
materials (with algorithms that are improvements over what DCC has)
and believe me, with "sufficient" generations, the degradations can be
quite severe.  But you have to remember that interactions with
specific audio materials are the rule.  In other words, how bad a
degradation is within any given tiny time slice depends on what
musical materials are in that slice.  There are no general rules, but,
typically, percussive sounds suffer (e.g. castanets, glockenspiel,
etc.).  Under "casual" listening conditions (e.g. like those of the
Stereo Reviewer) the distortions are very hard to pick out.  To
maximize hearing them, you need very precisely controlled acoustic
listening conditions + a golden ear.  In other words, the algorithm
can do a superb job, one which "normal, casual" listening will accept
as "CD quality".  But MD or DCC are NOT professional formats, nor for
true audiophiles in critical listening.  Worst case conditions, such
as those in CCIR testing that was done in my lab, need very specially
chosen musical (and other audio) materials, very special acoustic
conditions, and very special listeners.  Bear in mind too that
improvements are continuously being made to the algorithms but how
good they can be "at asymptote" is not entirely clear.  The
interaction with materials is the thing that must always be borne in
mind, as well as the kind of listening conditions and listeners..

I think the whole concept of "A/V" is mostly (not entirely - it does
have its merits) a gimmick thought up by the manufacturers as a way
to boost the sales in the land of mass-fi.

Someone said to himself, "Hey, I bet if we put some video switching

I'm about to build an amplifier to my soon completed two way loudspeaker system. I
have thought of using an active crossover circuit with two smaller amplifiers with
each speaker instead of a larger standard stereo power amplifier with passive
crossover circuits.
I'm wondering if anyone have any idea of what suitable output these would have 
in comparision with the passive alternative. I will be using 24 db per octave 
linkwitz filtering in any case. Will 2x20 watts be enough compared to 1x100 watts
in the passive system? Or should I go for a, say, 10+40 watts system instead?

Is this in the FAQ? :)

	Inexpensive does not imply low quality. There are several brands 
which are praised, by the audiophile establishment, as being fairly 
inexpensive, and still very listenable. Many of the Rotel's, Adcom's, NAD,
Denon's etc, I find to be an excellent value for inexpensive, high quality

they sound much better to my ears than many of the "consumer" product lines.

total is very expensive, to some $500 on a pre-amp is inexpensive. 

	For me, if I were to purchase a component today, I'ld be considering 
around $1000 for the amp, $1000-1500 for speakers, $400-500 for a CD player,

I have a Denon DCD 820 CD player and it has this "emphasis" indicator on

No where in the instruction manual does it explain what this feature does.
It only mentions "emphasis" feature in the description of the front panel

Visualize a standard stereo receiver.  Now add a couple of extra sets of input
and output phono jacks, each with a third jack labelled "video".  These
correspond to new settings on the source selector and tape switches:  TV, LD
player, and (in the tape area) VCR 1 and VCR 2.  Now you can push one button to
(for example) feed VCR 1 video to the TV and feed VCR 1's audio to your main
sterep speakers.

A recording company is under no legal obligation to code original
material as uncopieable or otherwise.  In other words, if someone
wants to sell a CD or DAT tape which doesn't prohibit multiple
generations of copying, then the producer/originator of that CD
or DAT is perfectly free to encode the SCMS with an 00 coding
for unlimited copying.

Regarding what kind of speakers for the surround -- the most recent
issue of _The Perfect Vision_ has an evaluation of three kinds of
surround speaker systems (not just the surrounds, but whole speaker
setups).  At the end of the article, the author made one broad
statement based on his evaluations: the single most important factor is
to match the overall tonal quality (primarily, frequency response)
among all the speakers.  In fact, he made the observation at one point
in the article that using all Radio Shack Minimus-7 speakers sounded
better than anything else he had tried so far.  That led him to insert
an equalizer for the surrounds to match them against his main
speakers.  Once that was done, he was able to achieve excellent results
and concentrated on finer differences among the speaker systems he was
evaluating.

I have an NAD integrated amp that has two sets of speaker outputs.
When I set the speaker select switch to A+B, the amp wires the pair
of speaker sets in parallel.  I have a pair of 6 ohm advents hooked up
tp the A terminals.  Now, here comes my question->

Lets say I take a single voice coil subwoofer driver, mount it in a
correctly dimensioned accoustic suspension jack, throw in a passive
low pass crossover, and connect the positive to the POSITIVE LEFT B jack
and connect the negaive to the NEGATIVE RIGHT B jack.  

Now, I switch the speaker selector over to B ONLY.  What does this do?
DOes the bridge my amplifier, like you can do with car amps?  Or, 
does this blow up my amplifier?  Do I get the sum of both channel's power
into this hommade subwoofer?  What happens?

Next, I set the speaker selector to A+B!!  NOW what happens?
Does THIS blow up the amp?  Remember, I have 6 ohm advents on A,
and an 8 ohm sub, quasi-bridged on B.  WHAT HAPPENS????
What happens if I use a 4ohm driver?

Thanks in advance,
