Be aware that $1295 IS a discount.

The 2Cis were 1295 + stands (125-250)
The 2Ces are  1495 and do not require added stands.

Vandersteen has limited distribution, and significant
discounts are not common.  Note that on this net, 2Cis
are going for $895-950 and 2Cs for $700+.

I've been putting together a pretty spiffy system for use with my band
(a 7 piece salsa dance band) that I can also use with jazz trios.  So far,
I've gotten the Mackie 1604 mixer, have a Bryston 250Watt power amp on
order, a 31 band stereo Rane EQ (primarily for home use, but it can be
used for performances as well), and am in the process of seeking out
speakers with these specs in mind.... can anyone offer any name brands
that would do?

The Specs: (2 speakers needed)
1. Each must weigh < 60 lbs MAX (not only would I buy and run the sound, 
   I have to roadie it as well).

2. Be rated for use with the power amp (250 Watt, stereo)

3. rugged, of course

4. be considerably better than "ok" sounding.  While dance music can be 
   played thru just about anything, there's got to be quality for the
   jazz and quieter stuff I do.

5. $1500 for the pair MAX...

6. High re-sale value
-----------
So far, names have run like:

EAW:     great recommendations, but apparently *very* heavy
Tannoy:  excellent recommendations, but something like $1500 Each, not pair
Peavey, JBL:  never mind, I'm not interested
Crate:   too ordinary, but maybe they are ok
EV:      again, too ordinary, but one cat really likes the stage speaker
         (i don't have the model number on me) since it's 30lbs and rather
         compact.
Klipsh:  ok for home, but I don't know anything about their stage speakers.

I will soon be looking to purchase a new pair of speakers for my system.
I will be able to spend about $500, so I am looking for 
speakers under $800 new (i.e. under $500 used.) They will be 
driven by a 60-watt Adcom amplifier. I listen to all types of
music, from John Zorn to Beethoven to Coltrane to Zeppelin. My 
priorities:

 - the speaker should be engaging. A counterexample: my father has
   a pair of Magnepan SMGa's and, while they sound wonderful, I 
   always find myself ignoring them.
 - the speaker should be tonally accurate. No recessed midranges,
   especially.
 - the speaker should not have any inclination toward 
   overbrightness. My current electronics tend to exaggerate any 
   such tendency.

I will post a summary if there is demand.

For 78s, the cartridge that I prefer is the Stanton 681EEE.  The Stanton
has an amazingly flat response and great freedom from overload.  It also
has the worst imaging I have ever heard in any stereo cartridge, but for
78s that's not a problem.  It also has some real difficulty reproducing
very low bass, but again for 78s that's not a problem.  

The Stanton comes with a 1mil stylus, and Stanton sells a 2.7 mil stylus
for electrical 78s and transcriptions.  If you need a larger stylus to
play pre-electrical recordings or damaged records, they are available from
a number of suppliers, among them Esoteric in Chicago.  As I recall,
however, there is an Australian company that also makes custom styli for
about $60 US a pop, which is pretty low, but I don't recall the name offhand.

There are other folks who prefer the Stanton 500 cartridge but it's much
more easily overloaded.  There are also some folks who prefer some of the
Shure cartridges (which I have personally never liked).  Your mileage may
differ, but these are all priced reasonably enough that you can get a few
and try them.  Espect to spend several times more for styli than for the
cartridge, since you will want a few styli of various sizes, depending
on what you are playing.

	While shopping at my friendly hi-fi dealer last weekend, the
owner made a comment about amplifiers that can deliver a great deal
of current. One of the benefits that he claimed for a high-current
design was better sound, specifically in the midrange.

	Does anyone care to comment on this statement? I don't know
enough about the basics of electrical engineering to effectively
critique it. (BTW-- if anyone could recommend a good book on the
basics of electrical engineering as it relates to hi-fi component
design, I would be avidly interested.)

	The amplifier that I eventually purchased was a Parasound
HCA-500. The manufacturer claims that it can deliver 50wpc into 8
ohms and 75wpc into 4 ohm. (RMS output.) They also claim 10 amps
average current and 20 amps peak. Does this strike anyone as being
a particularly good current rating? If so, why?

You should be able to rewire any stereo cartridge so the channel
windings buck each other instead of add together for mono.  This
would provide the desired vertical response.

With passive preamps, it's critical to keep the interconnects as short
as possible.  Anything over a meter is too much.

Probably not - check out the rec.audio FAQ. (I only read it yesterday!)
*BUT* if they liked the sound - its fine.

Normally one would use an electronic filter, between the pre- and
power-amp, and a second (power) amp for the subwoofers.

>3.  Is the Integrated Amp being beat upon?

It is.  (I assume the 'A'+'B' you mentioned are just 2 speaker sets on the
amp..)

They are (effectively) running the amp into just under 4 ohms.

>To cut a long story short, the Amp was getting burning hot

Class A amps usually run *very* hot: "burning" could be about 50C - well
within component specs.

If the tuner stills lights up, the amp has a major problem.
If everything is dead, it's probably just a fuse (maybe internal)

I would give the inexpensive D/A a shot.  I'm personally using an
Audio Alchemy D/A along with their DTI anti-jitter device.  The DTI
cures that which ails many inexpensive transports and is quite cheap
to boot.  In terms of bang for the buck, I think the outboard D/A will
do you a whole heck of a lot better than flat out buying a new
high-end player.

I am slowly putting together a vinyl based system (listed below) and
am about to replace my receiver with separates.  I particularily enjoy
the process of finding and buying used gear and plan to do that this
time.  Today my system mostly suffers from limited sense of performer
& instrument separation and stage (it's a too "bright" also).  I
listen mostly to traditional jazz (vocals and instruments) and have a
very small listening room (9X12).

Current System:

Sota Panoramas with low end "Original" Monster Cable
Rega Planar 3 with RB300 arm (audio-technica AT-71E cart.)
Kyocera R-861 integrated receiver (100wpc)

Considering:

Pre Amps

Superphon Revelation II
Adcom GFP555
PS Audio 4.5

Amps

Unknown except that each company has companion amps worth considering.

I have an opportunity to buy a Superphon Revelation II preamp for
under $300 (I'm a cheapskate).  However, I have also heard impressive
things about the sonic value you get with both Adcom's GFP555 and PS
Audio 4.5 preamps.  These seem to run a couple hundred more than the
Superphon.  Stan Warren (designer of the Superphon line and the S in
PS Audio) suggested the Rev II as an inexpensive launching point into
real high end.  I'm having a problem being able to audition any of
these units locally much less compare them against each other so I
would really appreciate hearing about your own first hand knowledge.

Aside from the Superphon's dual volume control problem, could those
of you who have some knowledge of these "bottom of the high end"
products (or alternatives) give me some arguments and suggestions on
such "starter sets"?  I'd also like your opinion on the reasonableness
of sticking with amps from the same company as the preamp?

Hi there everyone,

I have a couple of questions, with different scenario's:

I was at a friends place the other day and I noticed the following
setup :

Denon New Class A Integrated Amp (xyz 520 or something)
Cambridge Soundworks Ensemble System (dual subwoofers)

Well, I noticed that the Subwoofers were plugged in to Channel A (Left and
Right) and the Satellites into Channel B (Left and Right).  Knowing that the
Impedance on the Subs are 8 ohms and the satellites are 6 ohms, is this

1.  The correct way to hook this system up?

2.  The most efficient way to hook them up?

3.  Is the Integrated Amp being beat upon?

To cut a long story short, the Amp was getting burning hot (no-one noticed)
and after a while, it just switched off and has not switched on since.  The
Amp allows for current to pass thru to the Denon Tuner thru the switched out
on the back, but since there are virtually no lights/indicators on the Amp
(w/ the exception of a source selector LED (off)), does anyone know what might
have happened? Is is really major or just some fuse or something?

Please let me know...thanks in advance.

While shopping around for a used tube amplifier I came across a Dynaco. 
I understand that these amplifiers can be easily upgraded and modified. 
A friend of mine did this to a model that he had, but could not identify 
the one I had found while shopping around. The amp did not have any 
distinctive markings on it that I could find. The name on the front was 
simply "Dynaco", and there were two large heat sinks on the back. Each 
sink had fins that ran vertically about 3 inches apart. Any info as to 
the vintage and feasibility of improvement would be appreciated.

Most critics will agree, even though it is an analog recording.
Grammophone regards the Blomstedt / San Francisco Symphony Orchestra
version on the London label issued last year as the best digital
recording.  They didn't compare it with the Previn version.

The Ozawa / Berlin Philharmonic Orchestra version is well regarded
also.

After scanning through the ENTIRE r.a.high-end archives and carefully
read through all the related articles of how to make a pair of decent
interconnect, I ran to my local electronic supply store and bought 20
fts of Canare star-quad, and Belden 1192, a bunch of Switchcraft RCA
plugs, and 4% silver solder. 

The consensus in the archive (and further verified by my Audioquest
and Moster Interlink cables) seems to be, for shielded twisted pair,
connect the center conductors to the signal, and tie (only at the
source, CD for my case) the shield to the RCA shell. 

After 1 hr of "hard labor", I have a pair of shining (the Canare and
Belden cables look real nice) interconnect. For safety purpose, I
first connected them to NAD 5000/NAD 7100 driving a pair of Snell/E. 
Comparing to the Monster Interlink (CD), the sound is more refined,
especially on the mid range, though I didn't listen long enough to do
a detail comparison. 

So I then switch to the NAD 5000/the recently acquired Acurus DIA.
The result is very disappointing!!!
There's a constant low level hiss/hum. I have to turned up twice the
volume knob to get the same speaker volume, and all the dynamics are
lost. 

My suspicion is in the Acurus DIA passive preamp section, since it has
high sensitivity. My question to your cable guru is:
why and where did I do wrong, what kind of improvements I can make?
Shall I try different grounding methods, get a different cable (I
can't seem to find a local dealer willing to sell the Belden #89182
for < 50 fts)?

Any suggestions.

CM

BTW, the DIA is one hell of an amp, and yes, it's well worth it to

I've got an HK 870 amp with a very annoying problem.  
After just a few minutes warming up one or both channels begins
to crackle (static) very badly.  Its several years old and I'm sure that
the problem is thermal and component drift related.  I've got 
the tech sheets that contain the adjustment procedures along with
a good schematic, but it's annoying to have to rip it apart every
6 months or so.  

I've taken it to be fixed twice, neither time with much luck.
I'm just curious to know if anyone else has had this problem 
with the 870??

Thanks,
