I appoligize to others for doing a followup, but I was unable to mail Ryan.

Sony MDR-V6's are surprisingly good for being made by Sony.  They actually
got into Stereophiles Recommended Componets list.  They list for about
$100, but you can pick them up from Crutchfield (1-800-955-3000) for about
$80.  They fit all of your requirements.  Very good at blocking out external
sound (put you in your own little world) and the sound qualty is quite
good.

Asside from that, both Senheizer (sp?) and AKG make some very good 
audiophile headphones, but I know less about them.

I use a pair of Sony MDR-V6's, and I just love 'em.  They actually sound
a heck of a lot better than my main speakers (a pair of Bose 301's).
The frequency response is something outrageous, something like 5hz-
30000Hz, more than anybody could ever need.  They retail for around $90
now, but can probably be found for $80 or so.
Not only do I use these headphones (as if I count for something!), but my
school (a music conservatory) uses only this model of headphones.
Telarc, an all digital CD recording company, also uses this model.
So, assuming you purchase this model, you'll be in good company!
Oh, and they feature padded around-the-ear sealed cups, which is what it
sounds like you're looking for.  You can wear 'em for hours with no
discomfort.  (You may just get a little warm.  It's a little like wearing
ear muffs.)
I'm curious what others have to recommend.  For $80, I say you can't beat
this model.

In case you haven't all figured it out by now, I am looking
for new speakers.  I want to replace my mains in my pro-logic
system with new mains and a center channel.

Today, I auditioned Polk S-10 mains and Polk SC-100.  I was
very impressed with the S-10s both with and without the SC-100.
Package price is $750.

Opinions would be appreciated on the S-10s and others in this
price range.  I am so far considering NHT and Paradigm.
I have dismissed KEF, M&K and Infinity.  While I would consider
any speaker, I have discovered I usually like acoustic suspension
enclosures over passive radiators and ported enclosures.  Main
channels are 125W, Center is 40W.  Of course, I am partial towards
a matched set for the three components.

In fact, one of these companies based out of St. Louis and working in the
midwest area in fact was under indictment by the state of Illinois about 3
years ago. I was involved as an expert witness in the case. Both the
prosecution and defense had bad cases, the Illinois A.G. hadn't a clue as
to what he was talking about, and the claims that he was making were
pretty bogus, especially regarding "typical" parts cost to suggested
retail price ratios in the industry. They also hired two expert witnesses
who were complete bozos, and weren't involved in any way in consumer audio.

The upshot is that they reached a plea agreement where the company was to
advise its "dealers" in writing that they were to cease and desist under
penalty of individual prosecution from making the outrageous claims about
performance and price. They cannot claim that they sell for the prices
they do, they cannot claim the level of performance they do. Other than
that, they are not restricted from selling the equipment. In exchange, the
company agreed to accept all court and prosecution costs, plus a fine or two.

They still can sell the equipment, but the company must instruct its
dealers to represent them fairly. Now, of course, there are several
companies in this business, and this case involves only one.

Still, caveat emptor is the rule of the day.

I get the feeling that many of the people that have contributed to this
discussion/argument have little to no experience of high-end DAC's and
transports.  Of all those making such a noise, who will tell us what
the best is you've listened to (let's say best=most expensive system)
and if empirical evidence stands up to dry analysis.

I have another question.  Much of this argument seems to be that if two
transports can read precisely the same material off a CD, then they
should deliver exactly the same material to a DAC because we are working
in a digital domain.  The premise is a little shaky in that it is evident
(from experiment) that not all transports get the same material off of
a disc (the detail and extra-sounds from a top quality transport is absent
from a run-of-the=mill one).  I agree that with the present method
of transmission from transport to DAC there can and will be errors, and these
won't be corrected by retransmission because there is no protocol in force.
My question is:  why not?  The stated bandwidth required for data and
control bits is far below what can be carried on coax and, particularly,
optical fibre.  Why is it that no bullet-proof protocol is implemented
between the two?

Cheers

Gavin

Bi-Amping has many advantages, although hard to describe.

First of all, the crossover is placed prior to amplification,
rather than after resulting in far less robust crossover components.

Since the crossover is prior to the amplifiers, they do not
consume inordinate ammounts of power wasted as heat. you pay alot
for those watts, don't burn them up in a crossover.

Crossover impeadance for a speaker crossovers has to be low, resulting
in high power loss. Bi-Amp crossover impeadance is high.

Amplifiers are not working as hard. The bandwidth the amps are
seeing is much smaller, resulting in less phase distortion and THD.

Gives greater control over equalization of speakers.

 It had 18 bit D/A converter. IS 18 bit better than 1 bit D/A converter.

 Never trust a salesman!! He/she wants you to buy a more expensive product.
 Now, since SONYs can handle two pairs of 8 ohm speakers, then two pairs of
 8 ohms speakers connected with this receiver will be like having two 
 resistances in parallel.  This will give a total resistance of 4 ohms!!
 Which means that regular SONYs can handle impendances lower than 8 ohms.

I am also looking for an indoor antenna. I have also decided to avoid
active (powered) antennas such as those made by "Terk", (probably what
you saw at the Good Guys.  There are two "passive" models that I am
now checking out - one made by "Magnum Dynalabs" (their "whip" antenna -
retail $89) and the other by "Audio Prism" (model 6500 - retail $65).
The Audio Prism is a black rectangular box with an attenuater and a bias
control.  I just tried out a demo and it was a significant improvement
over the cheap dipole that you described.  It especially seemed helpful
in eliminating signal noise. i.e. sometimes the signal strength was 
actually less than with a dipole, but the signal was much cleaner.  I
am waiting for a demo of the Magnum Dynalabs to come in so I can test
it out.  As far as I know, both of these antennaes are available through
various high end stereo stores and maybe some mail order catalogs
as well.  Also, for those with deep pockets, there are of course much
more expensive models available. 

If anybody has any thing to add to (or correct in) this posting,
please do so by posting.

I doubt it's really a significant problem.  Consider all the bits
