There is often talk of the sport of falconry on this newsgroup, and such
threads often decay into arguments over the rights and wrongs of the 
practice.  In particular, I have heard people who accuse falconers of
"kidnapping" birds from the wild, treating them as pets, or otherwise
mistreating them.

I would like to pass on a passage from the book "Medical Management of Birds
of Prey", by Dr. Patrick Redic, DVM.  Dr. Redig is considered the country's
foremost authority on raptor care, and with his forgiveness I wish to quote
from this text:

"One of the most meticulously cared-for patients that an avian veterinary
practitioner is likely to encounter is the trained falcon.  The person
possessing such a bird has undergone, as required by a uniform nationwide set
of government regulations, a program of examination and facilities inspection
that not only insures competency but also dedication to the sport.  The 
raptors utilized have been taken from the wild as nestlings or free-flying
first-year birds, or more recently, there is an increased number produced
in breeding projects.  It is against regulations for there to be any monetary
or other aspects of trade involved in the production and exchange of raptors
among persons, hence the birds have no inherent commercial worth.  Neverthe-
less, the bond established between falconer and falcon is strong, nurtured by
weeks and months of association which produces an extreme level of confidence
in the bird toward her handler and a deep respect on the part of the falconer
for this wild and independent creature that, despite daily opportunities to
fly off, chooses to maintain the cooperative relationship that has been
established.  Because of this relationship, the falcon (be it peregrine or
red-tailed hawk) is extremely valuable to the person who has her in his
possession."

There is no more qualified person to judge the well-being of a captive
bird of prey than Dr. Redig, so I would hope that those who are quick to
judge falconers will remember these words.

I shall add that this book, which I have found absolutely priceless in my
rehabilitation work, is available at a very reasonable price.  Interested
parties may inquire, and I shall inform them how a copy may be obtained.

I don't know about "invention of the decade", but there is at least one
"universal remote", the Memorex CP8, which will do the job.  It has a built-in
clock and can send a sequence of one or more stored control codes at a
programmed time.  

In fact, for those of you who are looking for a way to "time-shift" radio
broadcasts as you can do for TV with a VCR, this unit will do it for you --
provided that both your cassette deck and your tuner use IR remotes.  their
remotes don't have to be compatible with each other, as the CP8 can learn the
codes for each independently, and a timed sequence of commands can consist of
codes for several different devices. 

I think Radio Shack sells this remote these days.

One way that we hypothesized that they might work (over lunch) was to
take N equal-time slices out of an exponential ramp, where N is the
number of bits that you are converting.  You need to get your decay
characteristic right, of course (so that the integral of slice N is 2
times the integral of slice N+1, or vice-versa), but I wouldn't be too
surprised if this could be compensated as you used it.

I can imagine two advantages and two disadvantages of doing it in this
(hypothetical) way:

a1. doesn't need a speedy clock -- sampling at the bit stream rate is
    all that is necessary.

a2. it's probably easier to generate a precise exponential ramp than
    it is to assemble 18 precision resistors.

d1. you have to be careful of the high-frequency components of the
    ramp, since it isn't a sine wave.  The initial fall-off (or final
    rise) is pretty steep, meaning that it does contain so HF
    components.  Of course, if you keep them on a chip, that might
    not be such a big deal (after all, many computer chips clock at
    50-100MHz).

d2. I'm not sure exactly how hard it is to keep the decay exactly
    right, since resistors and capacitors do vary with temperature.
    I'd expect that you could monitor the final result of the ramp,
    and depending upon whether it was high or low, tweak the circuit
    up or down over time.

Several years ago, there were ads in the audio mags from a

memory dims.

It showed their woofer hooked to an AC cord, plugged into an
outlet.   But as other replies to this thread have shown, no
one burns in their speakers like that.    And probably only a
few VERY high end burn them in - if any one does.

I would like to purchase a bookshelf system to save space (and avoid annoying
the neighbors).  I need opinions on what real audiophiles think are good
systems.  I would like to keep the cost in the range of $750.  A little more
or a little less is fine.  However, if this price range seems a bit ridiculous
to those of you who know your stuff, please tell me so.  

I most frequently play classical CD's.  My power requirements are not that 
important, but I don't want a wimpy system.  I would prefer a remote (wireless)
In all I would like an elegant system that has ease of use and is well.
designed. (Isn't that what we all want?)

Thanks for your patience with my limited knowledge.  I greatly appreciate the
input.  (please make suggestions specific if possible)

None, the convertor you're talking about would appear to ahve a 
single-stage clock recovery circuit that can't both lock to the
data AND recover a silent clock.  As I cannot comment on
any specific bit of equipment and I do not have the prints
for the box you mentioned here, all I can do is speculate. I 
do know that convertors that work nicely with all sorts of
transports DO exist, and that some of them don't cost
a fortune.

As usual, audio seems to be behind the rest of
the world, where clean clock recovery seems to have been
examined rather more closely that rec.audio seems to think.

WATTS and Puppies may not be inexpensive, but they are certainly
a long way from being $220,000 a pair.  (Even the WAMM system is only
$125,000 according to the last Audio Equipment Directory.)

Having lusted after a pair of WATTS and Puppies for years, and finally 
getting a pair, I would say that they should qualify as one of the 
better speaker systems available.  (purposely understated)

	Well, (1) how big is your room, (2) how efficient are your
speakers, (3) what kind of music will you be listening to, and
(4) how loud is "loud"? 

	If you are going to buy the 7100, I would audition it against
seperates from Adcom or Parasound. Once you get into the $700+ range,
you can usually get some nice seperates.

The Sony Pro walkman WMD6C has Dolby C. It also sounds very good indeed.
The only potential problem with this is that it may not solve your
problem of carrying a load of stuff around with you because it's not
small, and it costs #250 in the UK ( I think I saw one for $349 in
the US ).

Also, this thing eats batteries quicker than most, I use NiCads only
and they work OK.

I'm a satisfied customer.

According to the salesman at a local Mid-Fi store, the standard
SONY line is supposed to shut down whenever the speaker impedance
drops down below 8 ohms.  If you wanted a SONY that could handle
lower impedance, then you'd have to spring for the SONY ES line.

The SONY STR790 (~$330) would be comparable to the SONY STX59ES (~$600)
as far as Wattage, however the ES line is supposed to work fine 
down to 4 ohms.  When you attach more than two speakers, the 
impedance ratings become even more of a problem.  If you
look at the fine print for many receivers, you'll see that 
they may be rated to 4 ohms minimum for 2 speakers, 
but 8 ohms minimum with 4 speakers (or 5 for Dolby ProLogic)
 
The SONY ES line is supposedly better made than the standard SONYs.

Instead of wasting tons of net.bandwidth with individual replies, I'll
try to summarize:

I agree entirely with Mr. Williams.  Yes, technically the quality of
D/A converters does vary, as the does the quality of the analog side
of a CD player.  

Beyond a certain point (I would say > $500 U.S.), the quality of the D/A
converter and analog portion should be sufficiant as to make any
so-called differences listening to real music close to impossible.
(I'm talking at CD player prices here)

Yes, listening to test tones and other artificial sounds might show
a difference, but detecting whether or not the 'distortion' in real 
music is due to the D/A converter or a true noise present in the
original recording is so totally subjective as to make any scientific
claims iffy at best.

Best to spend your money on a better room, better speakers, better
insulation.  Your fridge or air conditioner is probably polluting the
sound at a level that is a magnitude greater than whatever a decent
D/A converter would do.  Think about it, white noise is present everywhere
and we tend not to notice it.

Hello people,

well, it is the first time I write an article in this newsgroup, so please do
not get angry, if such questions are asked in loads. :)

I have to possibility to buy a Denon PMA 1560 remarkably cheaper than normal
list price (which is around 1340 swiss francs I think...). The things I wanted
to ask are:

1) I have a new pair of boxes (Heco Cantata 550), that are rated with 110 Watts.
   Is the Denon strong enough for them? Or may the boxes burn out the amp?
   The amp is rather big, looking strong enough to me.

2) How is this amp rated overall?

3) It has a print on its front: Mos super optical class A. What does it mean.
   (When I looked at it, I saw no optical inputs....).

I did not found any article about this amplifier in all the magazines I read
(is it that new?). And i do not thrust the things vendors say, so I tried this
newsgroup in hope to find any competent hifier. :)

The standard digital filter has somewhere around 200 taps or delay stages. The 
actual number is always an odd number (for example, the ubiquitious NPC 5813 
(Burr Brown's DF-1700 equivalent or is it the other way around?) has 199 taps. 
The reason for the odd number of the filter taps is for symmetry around 0.)
The filter usually has lower than +-0.0001dB passband ripple and more than 
100dB of stopband attenuation. So I wouldn't be too worried about using 
"off-the-shelf" digital filter like the NPC 5813 or the DF-1700.
