	   I've got a Sony CDC C77ES ($500), and I really like it, but I wish
   I had waited for the new Onkyo 6-disc changers.  Very sweet.
	   Go for a carousel:  magazines may be more convenient, but they make
   A LOT of noise when switching discs, and all that open space inside the 
   player just makes me nervous.  If that doesn't bother you, the its a toss-up.

[rest deleted]

Not all magazine-type CD players make a lot of noise.  I have a
Pioneer 6 CD changer and it's VERY quite compared to my sister's
Denon.  There's no klunky sounding motor.  But then again, the Pioneer
is 50% more expensive then the Denon.

Some magazine-type CD players can store playlists for each magazine.
This is useful if there's a certain set of songs on different CDs you
like to listen to.  Just put the CDs in a magazine, program the
tracks, and store it in the player's memory.  Then each time you put
that magazine in, it will automatically recall the playlist.  It
identifies the magazine by examining the first CD and comparing its
signature against the stored playlists.  Obviously the player will get
confused if you change switch any of the other disks, but I think
it'll just revert to normal operation once it detects an
inconsistancy.  

This may not be important to many people, but 6-CD magazines are
standarized, so if you have several CD players (say, one in your car
and one at home), you can quickly move the magazine from one CD player
to another.

I agree with you somewhat in that my system is inbetween 2 and 10K and
I've been told that there are better points to upgrade before my $400
CD player (like cables).  Right now I'm getting my speakers placed
correctly (or at least giving it a good try) and starting to listen
to cables.  Can't tell the difference between $60 and $200 cables so
maybe I don't need to get a better CD player. 8-)

Me thinks I may just get some more software before I upgrade my CD.
Or even get a good used $400 TT first!

>-Youngjoon

Just thought I'd broaden the scope of this thread.  I have a pair of 
Vandersteen 3 speakers driven by a Bryston 11B preamp and a Bryston 4B 
power amp interconnected with Straightwire (Laserlink?), and bi-wired 
with Apature flat cable.  The CD player is a mid-fi Denon DCD-1420.

I auditioned the Vandy 3's, as well as the 2Ce's, with both an Adcom 555-II
 and the Bryston amplifiers.  Although I must admit I wasn't as well-tuned 
to the amps as the speakers, I felt that the Bryston did a better job 
driving both models of speakers throughout the dynamic range of the disc 
I listened to (Beethoven's 5th Symphony by the Cleveland Orchestra, on 
Telarc).  I recall that the Adcom did an admirable job, especially for the 
price, but the Bryston drove the speakers more effortlessly in the loud 
passages.  I haven't heard it, but the Bryston 3B should be a good lower 
cost alternative to the 4B, with similar sonic characteristics.

The 2Ce's themselves have a similar sound to the 3's, but the 3's go 
further on the quality (ie. they have similar designs, but the 3's use 
better components).  This leads to lower distortion in the midrange, 
among other (in)tangible improvements.  The 3's also delve a little deeper 
into the bass, but this isn't their greatest advantage (which is their 
overall beautiful sound - clear, crisp, very good imaging, basically flat, 
and very involving).

I'm very happy with this combination, however, I'm still dying to hear the 
Vandersteen's driven by a tube amp!  

On a final note (is that a pun?), I've seen absolutely *no* discussion on 
Vandersteen 3 speakers over this newsgroup.  Has anybody auditioned or 
purchased them?  I'm very interested in other opinions on these speakers 
(hopefully good one's) since I'm a happy owner myself.  Does anybody have 
any knowledge about the design, drivers, etc.?  Do speak out...

Happy Holidays,

Although the speakers make the biggest difference in the sound- after all,
that's what you are listening to- the amplifier does make a difference in
sound also, but not as big of a difference, unless you make a huge jump in
quality. 
I upgraded my system from a Technics receiver to Adcom separates, and I
have noticed a considerable difference in the sound. Much smoother, more
dynamic range, especially noticable at higher volumes. 
Nakamichi is supposed to make very high quality stuff, but depending upon
what you are going to use the receiver for, there are better alternatives.
If you are going to use the receiver only for your stereo, I would suggest
buying separates instead of a receiver. IMHO, much better sound for the
same price.

Sorry, I left something out so I have to follow up on my own posting.

That is of course an N-channel power mosfet to be used in the current sink
circuit.  An NPN bipolar transistor will also work, but has a larger 
equivalent input current noise resulting in slightly worse noise performance.

I also failed to mention that a zener could be used to develop the voltage 
reference to minus V.  To bypass (filter) the reference voltage, use an
R-C filter, don't just put a cap across the Zener.  Connect a resistor 
between the reference voltage (the "bar" end of the zener) and the
non-inverting op-amp input, and then add a capacitor from the 
non-inverting op-amp input to minus V (not necessarily ground).
You should also decouple the plus supply voltage of the op-amp to
minus V.  

Hopefully, with this extra info, you can breadboard the circuit
quickly to see if it works for you.  It is supposed to be very
very quiet.

Parametrics should be only used as a last resort.    They don't
really work as well as they should.    You can get great
looking room charts that sound poor if you use EQ to overcome
other problems.

And you really would probably want to use 1/3 octave equalizers
- cut only prefered.

The above comes from experience of 'tuning' a room many times
in the studio.     As far as EQ goes, less is more.

    Pretty expensive answering machine. For the cost

Actually MD sounds like the perfect medium for answering machines,

    I fired up PerfectBox for this driver, but I think the results will not
    be to your liking.  In short, this doesn't appear to be a driver
    designed for subwoofer use.  I let the program use all of its default
    parameters for a 4th-order alignment, and it came up with a 2.23ft^3
    box tuned to 54Hz.  The -3dB point was 64Hz, and -10dB was 44Hz.  I
    played around with 2nd and 5th-order boxes, too, but nothing came up
    that looked like a subwoofer.  Never got the response down into the
    30's.  Sorry.

I darned near have my audio/video system complete (I just purchased a
Sony SLV-585HF Hi-Fi VCR to go along with my Sony STR-D1090 Pro-Logic
amp, Bose 301 II's {front L,R speakers) and old, cheapo Realistic
speakers {surround channel, needless to say})... anyway, all I really
need now is a good center channel speaker that will match fairly well
with the rest of my system.
As I said in the message subject, I'm not really loaded here (especially
after buying the receiver and VCR both within the past month).  So, my
center speaker budget is about $200 or (hopefully) less.  I know that
Kenwood makes a darned inexpensive center speaker ($129), and Infinity
makes one ($169) that would probably go quite well with the Bose speakers.

Does anybody have any thoughts on either of these speakers, or on any other
center speakers in the <$200 range?  (My other option would be to purchase two
low-priced speakers and have a 6-speaker set up, but finding two reasonably
good speakers for <$200 total seems a little unlikely.)
Also, what kind of frequency response will I need for a center speaker?  It
seems that the main output is just the vocal track.  Would 60-20000Hz be
sufficient?
Thanks for your help once again, everybody!

My understanding (i.e. the rumours I've heard and the articles I've
read) is that the reason DCC decks cannot record analog cassettes is
simply that that is a condition of the license you have to take out
from Philips if you want to make a DCC machine.  If that's true, it's
probably based in marketing reasons -- force people to eventually
migrate to digital-only.  Anyone here from Philips (or one of their
licensees) who can confirm or deny this?

To my best knowledge, the reason "high-end" people do not

Stereophile hates Carver (product?) is becasue of the
Carver challenge, in which Carver claimed and demonstrated
that he can imitate the sound characteristic of any very
expensive power amps by adjusting the "transfer functions"
using his <$1000 power amp.
By the way, I read all about this in the "audio update"

For me, personally; I think Carver's sound just fine...
And, I can't find any reason why Carver stuffs should

Arg. That's the problem I'm having. The music IS continuous if I shake
the MD. But after a vigorous shaking (music doesn't stop!) I put the MD
player on the table again the music stops for about 1/3 of a second! Is
this just my player or is this a common problem?

Also, is this buffer *10 seconds* or *3 seconds*? The manual says it's 3
seconds but everywhere else (ads, etc.) say it's 10 seconds.

Curious :-)  I have a Velodyne F1000, and it too hums (softly)
when all else is off and/or disconnected.  I think I've convinced
myself that it is the servo motor - which normally you would never
hear during actual sound production.  BTW, hearing this requires
some effort - I had to get down on the ground in front of it to
listen at the cone.  I have mentioned it to Velodyne, but no
response from them yet.  At this point, however, I turn it off
when all else is off :-)
