Subject: Feelings on Phillips CDC-935 or Onkyo DXC-606 changers?
Date: 15 Oct 92 19:17:15 GMT
Article-I.D.: vcd.Bw6G8r.DIC
Followup-To: poster
Organization: Hewlett-Packard VCD
X-Newsreader: TIN [version 1.1.4 PL6]

I'm thinking of replacing my current (Kenwood) CD player with a new 
carousel changer now that they've been out for a little while and 
hopefully had the bugs worked out of them.

I'm thinking of either the Phillips CDC-935 or the Onkyo DXC-606.
Both are within $50 of each other in terms of price.
 
I like the fact that the Onkyo is a 6-disc mechansim, but I'm a little
worried that this is "too new" and may have mechanical problems.  The
one thing that I _really_ like about this Onkyo player is the "random"
music calendar.  Every other CD player I've seen just lights up the
tracks you've programmed (i.e., the [5] is either on or off.)  The Onkyo
has the ability to display any number from 1-19 in any of twenty
positions, so if I program tracks 9, 5, and 2, I see "9  5  2" on their
calendar, where as every other player (at least that I'm aware of!) 
would just light up [2], [5] and [9] giving no indication of the order.
I also think that when the Onkyo is is random mode, it shows you the
random order it selected.  Nice.

However, the Phillips CDC-935 is _supposedly_ a better unit in terms of
performance.  This is what I've been told.  I haven't had a chance to
actually listen to this unit, but it supposedly uses a good D/A converter
and sounds better than the Onkyo.  It also has a "music file" capability,
which holds 200+ discs (not nearly enough for my collection of CDs, but
what can I do?  How come they don't have SIMM slots in these things? :-)
This is a 5 disc carousel, which is supposedly a "proven" design.  
Phillips also invented the CD and supposedly knows what they're doing,
blah, blah, blah.  I was all set on the Onkyo when this wrench got 
thrown into the works.

Both changers will supposedly let you change some of the discs while one
of the discs continues to play.  That's nice.  But I want to know if I
should sacrifice the really neat display on the Onkyo for the (supposed)
better audio quality of the Phillips.  If the difference is 2dB of
dynamic range or 3dB of S/N ratio, I think I'd rather have the Onkyo.
But if Onkyo is known to have reliability problems and the audio quality
is noticeably different, then maybe the Phillips is the way to go.

If there are OTHER units I should be considering, please let me know!

Any comments, recommendations, or suggestions would be greatly
appreciated.

Regards,
Ed

Hi all.

I have a set of ADC 3-way speakers. The 4" midrange in one of the satellites
died, and I would like to replace it. Problem is, ADC no longer exists! Does
anyone have a suggestion as to how I could replace the speaker (since I don't
really know the details/specs)?

Please e-mail suggestions. Thanks for the help.

Has anyone added a digital output to a cheap CD player for use with an external
D/A converter? I am adept at electronics construction and design and it seems
to me that this must be a very simple operation (conceptually). I seems that
all that would be necessary is to tap the digital signal at the appropriate
location between the transport and the D/A converter electronics in the player
and run it through some line driver. Parts couldn't be that expensive.

Am I in left field here?

By the way, I am interested in adding a coax (no optical) digital interface to
a Harmon Kardon HD7300 CD player. I understand that this transport is probably
adaquate enough to be used with fairly good (e.g. $500-$1300) D/A converters
with decent results. This intended to maybe get by until I can get a decent
transport.

Ideas? Suggestions? SCHEMATICS!?

My comments are in reply to a recent post comparing the 800's and
801's. Although I did not audition the 800's, a friend of mine
mentioned very accurate bass reproduction along with huge soundstage.
There was a bit of coloration in the midrange area due to the fact that
the tweeter is located "above" the two midranges instead of being in
the middle as in a traditional "D'appolito" configuration. About the
801's which are considered the "Reference" in classical music
recording, I auditioned them at a local B&W dealer. IMHO I found them
to sound clean but they lack the dynamic extension found in similarly
priced speaker like the Thiel's. I liked the midrange which sounded
smooth and unfatiguing. The electronics used were Mark Levinson amp and
preamp driven by a Revox CD player.  I wouldn't say they sound boring,
but they don't have the punch and slam that you expect when you pay
~6000$ for a pair of speakers.

Recently, I bought from a fellow a pair of B&W DM 330 speakers for a
terribly low price.  They were added to the following system:
Adcom GFA-535 amp
NAD 1300 Pre-amp
Sony CDP-87es  CD
Straightwire Laser-link interconn.
Monster-Cable 10-guage cables

     As you can see, the above system is a mix and match setup that has
as many personalities as components.  I'm very curious on other people's
impressions of the speakers so that I can figure how the speakers relate
to the rest.
my impressions are:  Very well detailed, perhaps a bit hot in the high.
maybe overly crisp is the word.  The imaging is wonderful.  Depth is
helped by a phono, but soundstage is lost.  The room is pretty tight as
far as space.  Im siting perhaps 1.6-1.7 Xs there distance apart in front
of them.  A sub-woofer will definetely be nice when I move to a larger
room, but in the mean time, the base is a little left out, but not badly.

Please send any and all of your experiences with these speakers...

the article in MIX (trade mag for professional recording artists, and hacks

Interesting--I was over at ListenUp shortly after the 800s had just come
out and their high-end room had a pair of 800s, 801s (w/ ListenUp's filter),
Apogee Divas, and WATT/Puppy combos.  At the time, I found that I liked
the Divas the best, the WATT/Puppies were a respectable second, the 801s
a close third, and the 800s a distant fourth.  They told me at the time
that they were working on a filter for the 800s similar to the one they
made for the 801s--do you know if one was in use at the time you listened
to them?  (Incidentally, at the time I auditioned them, the associated
electronics were mostly ML, though I don't recall which CD player they
were using with the 800s.)

I am in the market for a new turntable, arm and cart. My budget is
$2000-2500 max for all three together. I currently have 350 records, but
probably will buy very few in the future. I would be interested in 
responses to the following:

1. Given the size of this collection (small by audiophile standards, i guess),
does it make sense to spend up to 2K. WOuld it make more sense to
get something like a VPI jr. or a Linn Axis, which weighs in at close to
half my budget (minus cart.)?

2. I am interested in the LP12 Linn (Basik power supply) vs the VPI HW19 III
for tables. In each case, i like the fact that the table can be upgraded,
in case i ever decide to do so. Comments on which way to go? With the Linn,
the upgrade option is a better power supply; with the VPI, there are more
things you can upgrade, like different platters, armboards....

3. My current preamp (Bryston .5B) has a MM phono stage, so i will go
with a MM cartridge. Any reccommendations? (I do plan a preamp upgrade in

a year. At that time, should i move into a moving coil?)

4. Withe the VPI, one has the future option to add a parallel tracking arm;
how do these compare to the usual tangential ones?

Just a couple of observations offered without comment:  a long-time
Acoustat engineer claimed the main reasons they moved away from
direct drive ESL's to transformer coupled units was two-fold:
First, the amps had reliability problems, and failures tended to
be dramatic, and second, its apparently hard to market a powered
speaker of any type, customers prefer to pick out their own amps.
The Acoustat direct drive amps are rather collectible now, and
go for a rather high price compared to their new list value.

Second, Macintosh still produces solid state amps with autoformer
outputs, including their latest flagship model.  Don't know about
the lower powered units.

Well, the discussion continues bewteen Mr. Motoyama and myself about
direct drive electrostatic loudspeakers. I, frankly, am growing a bit
weary of the discussion, what with Mr. Motoyama hauling out his models for
display and I hauling out my measurements to display and point out how his
models don't predict the measurement very well at all. And this is my
point. His models do not predict the known reality very well. Now, I would
suggest that the flaw is in the model, not the reality (if for no other
reason than it's a lot easier to change the model than to change the
observed reality. As long as Mr. Motoyama insists on the validity of the
model and fails to resolve them with measured reality, the discussion can
not advance.

One correction, though, I need to make, then I will graciously bow out of
the discusssion. I had made several assertions about the inpedance curve
of the Quad electrostatic, to which Mr. Motoyama made come counter
assertions based on his knowledge of the Quad ESL-63. In fact, I was
discussing the impedance curve of the ORIGINAL Quad electrostatic, not the
ESL-63. The original was far more conventional in nature, being a two way
system with two bass panels and a single segmented tweeter strip in the
center.

I will leave the discussion with a single remark. I will concede the evil
of transformers (though not necessarily for the reasons Mr. Motoyama
advances). Let's get rid of them! Fine, now, for whatever the reasons, we
have eliminated the transformer. Now what?

Well, we've just solved the easy part. What have we gained? Well, we've
just pissed off a month talking about 1% of the problem.

As I wrote in the latest article, my models DO predict the known reality, the 
excessive current and threatened stability, very well. The models are good 
enough when they account phenomena that we are interested in. They should not 
be blamed because they can not account ANYTHING Mr. Pierce want.

So, I do not intend to claim that Mr. Pierce's model for the dynamic speakers
does not work because it lacks any radiation resistance. The model might be
enough for his purpose though I do not know what it really is.

We should recall the history of 'trnsformer elimination'. It is never "easy"
one. In the times of tubes, designers could not eliminate them till SEPP
concept was established and low rp, high parviance tubes were developed.
SEPP tube amps still have problems in the way of driving power tubes.
Even in the age of transistors, designers used transformers for long time.
They only managed to eliminate them in the end of 60's and completed in early 
70's as direct coupled, pure complimentary, SEPP OTL's. In this arrangement,
they, at the first time, can feed back the output signals at any rate they 
like and, then, the problems of pass band width and nonlinear distortion both 
in amplitude and phase ultimately solved. Without any doubt, the most tough 
obstacles to solve the problems were transformers. 

Thus, talking on eliminating transformers can not be called 'pissing off'
unless Mr. Pierce wants to 'piss off' the whole history and whole effort 
ever made for eliminating transformers.

Even Mr. Pierce really thinks that it is easy, it is nice strategy to solve
easiest problem first, isn't it? In fact, we have already done it for electro-
static headphones! We have no positive reason to give up this for ELS's.

   >I will concede the evil of transformers (though not necessarily for the

 I currently use Sennheiser HD-530s at work, and HD-540 Reference Golds at

more sound to the outside world than I wanted (bothered co-workers, etc.) so
you may want to consider the environment in which you will be listening.

One problem I discovered was that they showed just how lousy my portable CD
