         Hello
           I have a pair of Kef C-90 speakers.  Great speakers.  I
         suggest Kef without any hesitation.  Has anyone tried the new
         Q series from Kef?  I am told the Q series is replacing the C
         series and the sound is quite improved (brighter w/o loss in
         the low end).  The guy at the store said everything was the
         same, except a different midrange/tweeter cone and speaker. 
         [The speakers are two-way.]  He said the cross-over
         electronics is the same.  Is this true?  Is it possible to
         buy just the cone/speaker?  I could then upgrade my speakers! 
         Yeah!

Hi,

I recently got a copy of J. A. Mitchell's "Golden Area RCA Records" list,
(c) 1985, 1987, pp. 11-24 and "Victrola Stereo Records" list, (c) 1986,
pp. 25-30. Has someone the whole list and/or is there a newer one?

One page 25 Mitchell mentiones the encoding of the embossed number, which 
can be used to figure out when the original cutting master of a Victrola
was made and which follows the same coding as the LSC series. He writes
that this code "is shown on page 7", which I don't have.

Can some, who is in possesion of this page 7, mail me this code?

[Post it. -tjk]

Thanks,

Dieter

Does anybody have any idea what this person is talking about?
I have seen other discussion that said Nakamichi used non-standard
bias and equalization in their older tape decks.

Request #2: I've now heard from three people that crossing over from older
Nakamichi to other brands may be a problem. Apparently Nak tapes sound
fantastic on Nak decks, and not quite right on other machines. This is said
to be mainly a problem with the equalization of older Naks. If you use Naks,
can you tell me if they're new or old, whether you have had this problem, and
what you can do about it?

As a Rega dealer I have the following advise: Take the felt mat off the deck.
Start the platter. Look at the pulley from above. It should be steady, ie not
rocking in any direction. If it is rocking you don't have a clean drive,and
need to adjust the pulley/motor.

Also clean the belt with a damp cloth. (this should be done every second
month or so.

  Netters -

  I'm looking for information on the E.J. Jordan 50 mm treble driver.  More
  specifically, I am looking for typical Thiele/Small parameters,
  recommended crossover frequencies/slopes and other do-it-yourself
  information.  

  The 2/88 issue of SpeakerBuilder mentioned an E.J. Jordan Owner's Club. I
  would think the club, if still in existence, would be able to provide the
  information I'm seeking.  The only other information I have is from the
  2/89 SpeakerBuilder.  The issue stated that E.J. Jordan USA was no longer
  distributing the Jordan drivers and all sales were being handled by
  "Ted Jordan, The Dak, Manorbier, South Pembrokeshire, SA70 8QR England,
  (011) 44-834-871-209". Maybe some of you netters on the other side of the
  Atlantic can help out.  Thanks in advance for any information/assistance.

Hi,

I'm working on doing some data collection involving an analog signal
down around 17KHz.  A way of doing this that has come up is to use
a DAT Walkman type unit to record the data and then get the digital
out into a computer.

The question is, has anybody done something like this.  What is the
real bits per sample (dynamic range) of the Sony DAT Walkman for
instance.  Does anybody know the specifics of the digital output
(or a device that could interface a DAT player to a workstation).

Thanks

Hi Folks,

All this talk of the legendary Dave Brubeck and his much sought-after
recordings have me wondering:  which albums specifically are the ones
that were well made enough to worth a listen to?  I looked through my
dusty bin and found an old 2-record set pressed by the Direct Disk Labs 
in 1978, by the New Dave Brubeck Quartet called "A Cut Above", consisting 
of a number of old time jazz favorites, featuring Dave and his 3 sons.  
If 1978 was "New", what was "old"?

In response to requests for comments about Adcom equipment:

I bought the Adcom GFP-555/GFA-555 preamp/amplifier combo about three
years ago.  I have the amp driving a pair of Thiel 3.5's.  Most of my
listening is classical, but the occasional C&W or Rock cd does find its
way to the player.

This is not a system for those who like anything more than straight-off
the disc sound.  It is perfectly capable of blowing the windows out, but
I have rarely cranked it up beyond my neighbors' pain thresholds.  The
GFA-555 delivers something over 350 watts/channel to my speakers, I
figure.  Thus, I tend to sweat a bit when the volume knob gets more than
about 40% around.  There are a couple of "warning" lights on the amp to
indicate clipping, but I've never seen them flicker, even when playing
Mahler (or Dire Straits) at frightening levels.  The best thing about
the system I have, imho, is the staging.  On a good recording, the stage
image is precise and there is no traveling--instruments seeming to move
laterally.  I don't know how much of this is due to which component, but
the combination works well.  (Note: You should listen to equipment you
are planning to buy together.  I don't understand why--and don't really
care--but it's a fact that amps and speakers, and to a lesser extent
preamps and amps, sometime do weird things when connected to each other. 
If you are planning to replace a preamp,  ask for a home try-out of the
product in your system.  If that can't be done, get a seven-day,
no-questions-asked return guarantee *in writing*.  If that can't be done
either, shop elsewhere.)

The preamp is a fairly plain beast, but it has more controls (bass,
treble, balance) than I ever use.  It seems virtually colorless, even
when playing LP's (and actually preamplifying), which I still do once in
a while.  The switches and controls are absolutely silent.

When I bought the system, I intended it to last the rest of my life.  I
am pushing 50 and got twenty years out of my last rig, which was much
less "high-end."  So far, so good.  My reading seems to indicate that
the 565 is a slight improvement over the 555.  If your ears like the
Adcom's connected to the speakers you like, I'd say, "take the plunge." 
My experience with the Adcom/Thiel set-up has been uniformly happy. 
Adcom is quality stuff.

It was one of those labels sold through Publishers Clearinghouse, if I remeber
correctly. They had some interesting releases, Beethoven Symphonies with
Josef Krips, compedium of Edison Cylinder recordings, etc. etc. Not great

Howdy,

I'm looking to get a good pair of speakers to upgrade my system.  I'm
seriously considering the QUAD ESL63 professionals
as an alternative, particularly
since I may have the option to get them for about $2500 per pair.

Years ago the Quads were the best (but almost the ONLY) electrostats
on the market.  When I listen to them now, they still sound wonderful,
and have an absolutely stunning soundstage.  The imaging is really
terrific.  But, of course, they don't play very loud, and the deep
bass is missing.  Do any other new Electrostats improve on this
performance?

I haven't heard the speakers with the optional subwoofers, but general
experience with mixing the two speaker types leads me to guess it won't
sound all that good.  On the other hand, I listen largely to rock/pop music,
and would love to have a good deep bass.

Also, I am curious as to what the price of a pair of QUADs is in the
US.  I am in Germany now, although I will move back to the states in
about 1 1/2 years.  What about shipping these things?  Are there
any special problems aside from the size?  Are they unusually
prone to shipping damage?


My system, btw, is a NAD 5000 CD player, a passive preamp of very high
quality, and a pair of modified Dynaco MkVI power amps.  THese are
120 Watt mono tube amps using 4 8417 output tubes each.  I have replaced
all the caps with high quality pp or ps caps, and added individual
bias supply adjustments for each tube to keep crossover distortion
to a minimum.  A heavier duty power supply is next, but thats the
subject of another letter.


Thanks for whatever wisdom is available on these speakers.  I am interested
to hear all opinions of them, and also what they typically sell for in the US.
What other speakers in this price range I should investigate (both 
electrostats and normal), and what the subwoofers are like


Thanks,

How about a Vifa tweeter / Cabasse mid and woofer combination?  I'm thinking

Electically this will work fine. With active components (as all
CD players and amps are) you actually want the source impedance
much much less than the load (amp input) impedance. The larger the
ratio the better. An "ideal" amp has the following characteristics:

1. Infinite input impedance
2. Zero output impedance
...

Of course this is not possible, but you can approach these ideal traits.
22000/120 is a pretty large ratio. Usually pre-amps have more current 
drive capabilities than do CD players. CDs players are designed to
drive very short interconnects (<2m), pre-amps are expected to drive
longer length. The designers choose the output characteristics
accordingly. The op-amps in CD players are probably the same kind for
fixed output or variable. Just don't to long with the cables connecting
the CD to amp and you'll be fine.

Date: Tue, 21 Jul 1992 13:08:25 GMT

I have recently been considering replacing my M-L Sequel IIs and have
started to listen to some speakers.  Consequently, I have began ponder 
a couple of things pertaining to soundstage information presented by a
loudspeaker.  I think the question is primarily related to the radiation
pattern of speakers, forward radiating vs. dipolar or bipolar speakers.
I have noticed that most well designed, forward radiating speaker systems 
give pinpoint placement of instruments on the soundstage.  These systems
usually consist of forward firing conventional dynamic drivers, sometimes
having a rear firing port.  (Notable examples are WATT/Puppies, Avalons,
Hales, the new Aerial speaker, etc.)  Whereas, bi/dipolars, which include
virtually all electrostatic and panel speakers and even some systems with 
dynamic drivers such as the Mirgage M-1,3,5, usually provide somewhat
more of a diffuse soundstage.

I had a conversation with someone who suggested that the conventional
forward firing systems were the speakers that more accurately reproduced the
information on the recording.  I concede that this may in fact be correct
considering the placement of microphones in minimally miked orchestral
recordings.  However, this is not the perspective of someone sitting
in the audience.  There, at least from my experience, one does not 
perceive the pinpoint imaging that some speakers provide but more of the
diffuse soundstage that bi/dipolar speakers produce.  The problem is that
I suspect that this effect produced by the bi/dipolars is not completely
accurate, but is just an effect.  
 
I am not saying that I prefer one perspective over the other, some of the
speakers from each category sound very good to me.  (However, to my ear,
WATTs/Puppies are the best sounding speaker I have heard.)  It seems that
in one sense, bi/dipolars can produce an effect that seems more natural,
but, on the other hand the perspective presented by the better front
radiating dynamic speakers is probably more accurate.

Hello, everyone.

Has anyone removed the cartridge body on a Sumiko Blue Point in order to
get improved sound?  

Removing cartridge bodies on expensive models like the Spectral cartridge is
supposed to make a significant improvement, so I suspect an inexpensive
cartridge would show an even greater improvement.

I have considered buying the Super Blue Point (~$300), but maybe a do it

I've had a pair of Apogee Centaur hybrid speakers for about a year now.
My original amp and preamp, an SAE and Proton, I sold because they didn't
do the Apogee's justice.  I swore then that, at the recommendations of
Jason Bloom (pres. of Apogee), many friends and my own dear ears, that
I'd buy a Aragon 2004 or 4004 and the matching preamp.  Well, I've
discovered that even a not-so-great amp and preamp (namely my departed
SAE and Proton sidekick) are better than nothing, and I've now decided
that (against the advice of my loan officer) I'll have to buy this new
equipment.

In the name of justice, fair play and affordable high-end, does anyone
know of a source for used/discounted/black market Aragon equipment?
I'd love to dish out $3k, but I'm more willing (and able) to put in the
effort to track down a better buy.

Try either the Tara Labs Space & Time Passage Power Amp (100W @ 8 ohms, 150W @
4 ohms)--a hybrid design using a 12AU7 input tube and a 12BH7 driver tube as
well as mosfets (approx. $1250.00), or either a pair of old Dynaco ST-70's
modified to the hilt (I recommend Curcio or Sonic Frontiers) or one of the
Dynaco ST-70 Mk II's--priced at about $700/pair (if you do the modifications
yourself) or $2000/pair respectively.

You can also try the Sonic Frontiers SFS-80 stereo tube amp, priced at $2750 or
the SFM-160, priced at $5495/pair.  They can be reached at (416) 847-3245.



Or hell, you can go to your local used audio bin, buy up an old Hafler or B&K
and send it to Lazarus where they will make it a hybrid amp for $799. (Hey,
it's worth a shot if your low on green...)

Have fun agonizing over all the choices, and try to listen with your ears
rather than your wallet if you can.  ;)
