Apparently the story also goes something like:
The rings affect the lens (tracking and focus) servos more. The angular
momentum of the disk must be relatively high but I suppose the spin motor
could cause problems. However, with a warped or off centre disc, the track
and focus servos will be going in and out as the warps go up and down and
side to side. Apparently the rings help the focus servo, which can draw
quite a bit of power with a badly warped disc or a disc that isn't spinning
around a perpendicular axis (to the drive spindle). Given that the rings are
so light and that the disc spind so slowly (500-200 rpm aint fast) I can't
see how it could help flatten what is a fairly strong disc that easily.
Though there is no reason for me to say that it would be impossible under
all circumstances with no audible improvement.

What I can't get is how they could have a 'major' effect when there is a
piece of glass connecting a transport and dac, and digital errors are in
actuality so incredibly rare with a clean disc. Anyone know what a Nyquist
Eddie is??? Sounds like it would be something that actually exists in the
realms of theoretical communications theory with a name like that, complete
with equations and all. Until I _hear_ the differences (rather than perceive
them, like the feeling of movement you perceive when you use a stationary 3D
flight simulator for the first time) and see the equations for the
theoratical realities (though I hate maths...) I will have a hard time
believing it all!

  Based on the room dimensions, I wouldn't select position b.  Surround
speakers shouldn't, in my opinion, be mounted so high, nor should they
be directed towards the seating position in this manner.  The viewer
on either end of the couch will likely miss much of the surround effect
because they will be able to localize the nearest surround speaker and
be 'pulled away' from the rest of the sound sources.
  I would think it better to try mounting the surround speakers lower
on the wall and direct them upwards towards the ceiling (depending on
the type of ceiling you have, of course).  This might preserve the
'wall of sound' (sorry about copyright infringement, Chris :-)) from the
rear.  I'm not familiar with the M3 but if I understand your diagram
correctly, this should not be difficult or aesthetically unpleasant.
  Of course, you could just try out a few arrangements (seeing as how
you own the equipment) and go with what sounds best to you.

Summary: reference 60 is cheaper but better
Keywords: infinity kappa reference 60
Organization: Computational Chemistry, ETH, Zuerich
Date: Fri, 9 Oct 1992 13:22:40 GMT

I just listened to the following
1. Infinity kappa 7.1              Sfr 1600
2. Infinity reference 60           Sfr 1340
3. Heco 'superior fortissimo 950"  Sfr 1600

For the prices in swiss francs, note that 1Sfr is approx
US$0.78
What surprised me was that I liked the reference 60's more
than the kappa 7.1's although they cost Sfr260 less.
The cheaper Reference 60s certainly had lot's more treble,
but, surprisingly, clearer bass. You could hear the distinct
twang that a bass sometimes makes.

Am I missing the reason the kappa 7.1's are more expensive ?
Am I brain damaged from listening to too many tinny speakers ?

I had never heard of the 3rd speakers listed above, the
Heco's, but I thought they also sounded better than the kappa
7.1's. I couldn't make up my mind whether I preferred the
Heco speakers or infinity reference 60's.

You have a slight problem considering a CD spins with constant linear
velocity (CLV), not constant angular velocity (CAV).  I believe a CD
begins spinning at about 500 RPMs gradually slows down to a minimum of
200 RPMs.

The length of the port is just that and only that,  the length of the
port.  It makes no difference if it passes through one, two or more
layers of cabinet thickness.

If the port length is .75" then you may be in trouble.  The size of
the port can be changed based on the length if this is the case....

Hi Netters!!!
   Just found you recently!  Can someone please offer recommendations
on fairly superior speakers (floor standing) in the 1000.00-1500.00
price range.  Are DCM Time Windows any good?  Is JBL still as good as 
it was, say 5-10 yrs ago?  What ever happened to Cannon operating
out of Van Nuys, CA?  Were they bought out by JBL?  I bought a pair
of Cannon 1032's in 1981 and they still sound as nice as they ever did.
Any opinion on the Bose 901?  What about Dahlquist?  Is anybody into
Kirksaedter?  Is Klipsch any good for other than base?  It has been so
long since I last looked into audio equipment that any advice will be
greatly appreciated.  Thanks!
PS  Would someone be so kind as to explain what is meant by a speaker's
driver?  Certain minimum-rated drivers require a minimum power rating
on the amp/tuner.

the difference in cables can be quite real, but it's not anything i have 
found because of exotic construction. the only difference i have been able 
to repeatably detect is low frequency rolloff because of 16 ga and 12 ga 
cable.

that's why i rewired my speakers. they came with 22 ga unknown

figure you spend $2000 a pair and get decent wiring, but you don't. i have

Just a reminder: There are several recourses for problems with sleazy mail
order dealers.  Some people have remarked that the Better Business Bureau is
generally on the side of the dealer, and likely won't be much help (think
about who the members are).  Most people already know about their recourses
available through their credit card company.  In addition, there are two more
allies in a situation like this.  First, if you feel you have been ripped off
and your order went through the mail, you can contact the post office and in-
stigate a mail-fraud investigation.  They are very serious about pursuing of-
fenders.  I don't even think you have to recieve the merchandise by mail, you
just have to place the order by mail.  This doesn't apply in a lot of cases
though because most orders are placed over the phone.

Your other recourse is the local police (where the business is located).
Police departments usually have a division that investigates cases of false
advertising, bait-and-switch, etc.  You should report this kind of thing to
them.  For all you know, the local D.A. may be waiting for just one more
complaint to put this dealer out of business.

For a glowing review of the Alon IV (the only review I have seen to

Systems has also reprinted this review.  Acarian can be reached by
telephone at 516-737-9369 and The Absolute Sound sells back issues for

dealer is a friend of Carl Marchisotto -- the designer/president).
Having always loved the Dahlquist DQ line, especially the DQ-20, I
looked forward to hearing Carl's latest, since IMHO, the new DQ line
was a real disgrace to the Dahlquist name.  Yes, they have "corrected"
errors in the original crossovers, but they still can't touch the Alon
IV's.  
	Now if I can just save up enough money...

	Has anyone seen a review of the Alon II?  Anyone heard the
speaker yet?  I'll have to drop by the dealer when I get back from
school... perhaps this weekend.
