	There is a CD about which gives you a series of recordings made using
different microphone techniques. It's by James Boyk(?), I think I have the
catalogue number floating about somewhere at home. Although this is only
mildly related to the original question, it does allow you to see what sort of
imaging you system can resolve.

   For once, Kurt does have a point....musicians often have been
   known to be satisfied with truly horrid audio systems.  

   I must confess that if given a chance between a $1.95 K-Mart AM
   special and no music at all, I'd have to think about it but would
   take the K-Mart and listen.

   And it is not at all unusual that musicians have truly horrid
   tastes in sound engineering.  After all, if you have the tympani
   and tubas blatting in your ears all day, it is hard to appreciate
   the sound of a solo oboe from in FRONT of the conductor.

   Note that this isn't all musicians...some have excellent taste
   and artistic judgment.  But a lot shouldn't be allowed within a
   kilometer of a mixing console or EQ.

    A bit of new Spinal Tap trivia.  I never knew the movie was
    actually based on a TV show.  Was the movie the pilot, or and
    entirely separate creation based on the same mythical BRB?

    And was it Squiggy or Lenny from Laverne and Shirley that played

    And why has that film become so popular all of a sudden?  I
    don't remember that many people who even heard of it in the year
    or so after release,,,I've even seen it on TV a couple times.

    But lately, it seems a lot of the younger element are quite
    aware of the movie...almost like it is becoming a cult classic
    like The Rocky Horror movie.

Got a quick question for all of you...

Does anyone out there have a schematic for a simple echo box?  I recently
was handed the job of "Chief Engineer" at our dorm radio station, and one
of the neat-o things that I promised to look into was building a box that
would give the station mike an echo effect.  If anyone has a design or
pointers to one, it would save re-inventing the wheel.

Thanks...

Hi there...

	I am planning on replacing my amps and a set of speakers.

	In the past, I have been using 2 Carver M4.0s bridged
into mono amps, each driving an Infinity RSIIIA. Since RSIIIAs
are pretty much fossils at this point, I am considering an up-
grade.

	I'm considering replacing the RSIIIAs with the new
Infinity Reniassance 90s. I gave a pair a listen a couple of
months ago, and I really liked them. Really bright and open
up top, when compared to the RSIIIA. Kind of like the old
RS2.5 of years ago, except with much tighter bass response.

	Although I have not had much trouble from my Carver
amps (I've owned 4), I have heard horror stories from others.
One suggestion I've heard is Hafler. The power range I'm in
the market for is 900 plus watts RMS, bridged or mono.

	Aesthetics are a consideration here, as are physical
dimensions, to some degree. This is going to be a home stereo,
and should look pretty, as well as sound pretty.

	Any info you can provide on the above, including list
pricing is appreciated. Opinions are welcome.

Thanks -- Mike

As a non-audiophile musician, I can't help gloating a bit. None of the

I'll second that.  I love Neil Young's work, artistically.  But from     
an audiophile viewpoint, a lot of it is terrible.  For example,
"Harvest" (great album, artistically) has extremely muddy sound 
whether on LP or CD.  When I used to listen to it on LP, I always 
had an uncontrollable urge to want to get up and clean the stylus!  
Alas, the distortion is on the master tape, because the CD sounds 
just as bad.  Anyway, Neil Young has pretty much disqualified
himself from commenting on audio engineering.

I'm looking into purchasing a portable cd player for less than $200.  Several
people in this group have recommended the Panasonic SLNP-1a for around
$125.  The consensus appears to be that this has the best sound as far as
portables are concerned.  However, is this unit well built (rugged enough for
hiking, camping etc.)?  Does it have rechargable Ni-Cads?  Other units I should
consider?  Any suggestions will be greatly appreciated.

Not if the shutoff is simply current sensing (which it probably is;
power sensing is more complex).  If the amp cuts off at a certain
current, the power delivered to the speakers is the same whether a
series resistor is there or not, since power = I^2 * R; if max I is the
same, and R of the speaker is the same, power dissipated by the
speakers is the same.  The series R dissipates additional power, which
the amp does provide current and voltage for.  But you don't hear it!


  >A much better answer is a amp that is happy driving low impedance loads.

Might very well be.

This thread is taking an interesting turn (an thus far avoiding a 
religious war :->)

The Klipshorn design is right around 50 years old and, judging from the
posts, still accepted as a reasonable design (this as apposed to the
general tone of posts when a company whose name rhymes with nose is
mentioned - but thats a religious war after all :->)

50 years ago the sealed box designs that are currently in high regard were
in very low regard (look at H.F. Olson's comments in his book "On
Accoustical Engineering" from this period). The only attribute that the
sealed box had going for it at that time was small size. 

Market pressure (as in "if you will build it, people will come") put the
engineering into improving the sealed box. Consumers needed small speakers.
Given the SIZE of some of the current high end sealed boxes, small size
is no longer a requirement. 

Now to the question - What work has been done in the past 50 years with
horns that would point to improvement (refinements if you must) to the
design?  Tony Burke and others mentioned a throat to mouth ratio which
had an effect on sound quality (as a starting point).

As to an attribute which might attract "the market" let me invent one.
The "james bond microphone thread" is pointing to crowding people together
with paper thin walls between them. Perhaps the market will require a
speaker system which delivers all the sound information but at low volume
levels. Horns are tend to be just as effective at low levels as they are
at high SPL. As to coloration, the sealed boxes of 50 years ago were 
somewhat less than transparent :->

So what's out there, and while we're at it lets open the discussion to other
"archaic" and / or currently not state-of-the-art designs

I'd like to know more about this CD Rot. Since you appear to be
knowledgeable on the subject, perhaps you could answer the following
questions for me:

1) How many rotten CDs do you have?

2) What does CD rot look like?

3) What exactly *IS* CD rot? A clouding of the acrylic on the data side?
Oxidation of the metal in the data layer itself?

4) What causes CD rot? Manufacturing defects? Poor handling/storage by the end
user? Laser Bacteria?

Agree that we should restarin ourselves on quoting prior posts (like this

Also, sometimes someone uses FOLLOWUP (what I have done to type this

POINT of the article being followed up.  Being interested in DCC, I
selected 2323 RE DCC/MD COMPARISONS, but what the writer (er-author?)

I suggest that we should use FOLLOWUP to convey a sense of what the

you want to talk about---for example  NEIL YOUNG (in reference to article ##)

Arcam Alpha.  B&W 610.  To pick two (that I like) out of thin air.
It's hard to predict US prices from UK ones, but I'd expect them to be
sort of in your price range.  If carefully positioned, the B&Ws will go
a bit lower in the bass (probably about 1/4 octave).  The Arcams on
the other hand are a bit cleaner, aren't as fussy about precisely where
you put them, and in particular don't mind too much being put fairly
near a wall.

I just bought a cassette/receiver for my car from them. I found their
salesman/purchase advisor very helpful and knowledgeable. Having told
him my price range and car model and make he came up with a suggestion
which was slightly cheaper than what I had expected. Their installation
kits are really good. Delivery was a day earlier than promised. I don't
know how easy returns are since I didn't have to and don't expect to do so.
In short I have been quite pleased with my one dealing with them. One
caution -- From looking at their catalogue it appears that car stereo
is their specialty I don't know about the rest.
I have no connection with Crutchfield except as a satisfied customer.
