In a review of the Vimak DS-2000 DAC in Australian Hi-Fi, the following
statements are made:
"The Vimak accepts up to 24 bits of external audio data. At present, the
standard CD data-stream cannot provide this level of precision, but it
seems likely that that by using presently unused channels on CD's to
encode additional data, 24 bit precision on CD, with no loss of playing
time, and no loss of compatibility, is more than just a possibility, its
a probability. In the US, the smaller specialist record labels are
already investigating the encoding algorithms necessary to perform this
clever trick."
I am seeking comments on these interesting statements, and any further
information that people may have on this. Is this of any relevance to
the current recording pratice of recording at 20-bits and Sony's SBM
process? Is this possibly used in the HDCD process where the New York
Times article stated that the HDCD process samples at several hundred
K samples per second, and 20 bits and then uses some algorithm to get
rid of redundant information? To exploit this potential we may see
completely new DAC's with DSP chips in them like in the Vimak.

Summary: After a year, I still LOVE my Snell Type B speakers.
Keywords: audio, hi-fi, speakers
Originator: tjk@csd4.csd.uwm.edu

A year ago when I auditioned many speakers and chose the Snell Type B, they
were very controversial in the audio magazines.  R. Greene from the Absolute
Sound loved them, while Stereophile said they were good but seriously flawed
of auditioning various speakers, I chose the Snell B speakers because they
provided me with the most satisfying emotional responses to the music that
I love (whether classical, instrumental or vocal music, jazz, or rock).
They also sounded to me more like actual live music sounds than other
speakers did.  In constrast to most speakers, they were not too bright (with
an apparently hyped-up treble), and they were capable of reproducing bass
at lower frequencies than most speakers.
   After a year, I can report that I am VERY happy I got the Snell Bs.  In
fact, I don't see why anyone would buy another speaker in this price range 
(including those costing $2000-$3000 more per pair than the Bs).  I have
heard, for extended periods, other speakers with outstanding reviews, like
the Pro-Ac Twos and Threes, during the past year.  And every time I hear 
these other speakers play music that I am familiar with and that I have 
heard on my own system, I prefer my Snell Bs.  (The ProAc Threes are better
than my Bs at soundstaging, thoug, although that may be due to my very small
listening room.)  Even in my small room, the B's are tremendous.  (No, I 
don't have any connection with the company.  I just love these speakers.)
FYI, I use a Counterpoint 5000 preamp and Counterpoint 220 amp, lapis
interconnects, and the B's are bi-wired with Audioquest jade and clear (with
the clear on the bass path).  At this point, all I need is more well-recorded
music.

     I have a pair of Sub 1's, 10 months old, which deserve all the praise
     afforded them in recent commentaries. But my priorities are shifting
     toward an outdoor hobby (blasphemy!), and I'm considering liquidating
     my high-end system. My Sub 1's are custom-finished in a light *white*
     stain over cherry veneer -- gorgeous. I did not have them urethaned,
     so that choice is left up to you (I liked them flat). I think I respect
     these babies too much to subject them to shipping, so I'll strongly
     favor local buyers. I'm asking $640.00. [But I'm getting pangs already,
     so I reserve the right to change my mind and keep them!]
                 New would cost: $799 + $60 S/H, plus $100.00 assembly = $960.

Hi,
	I have an urgent question about interconnects and speaker
	cables for my new system...there seems to be too many different
opinons about the wires.  My friend, whose system I've listened to
before, recommended MIT interconnects and cables for my ARC system.
But when I talked to the salesperson, he was totally against this and
thought I should try wires with Litz, in this case, Hyperlitz design to
complement the ARCs (He mentioned the wires inside ARC components are
"twisted?")  So I opted for Kimber Kable Silver, but ultimately
switched to Audioquest Lapis interconnects and Audioquest Clear speaker
cables.  Does anyone have any experience with ARC components or these
wires?  Is the Clear 6N copper?  My friend was distressed when I told
him what I purchased; he insisted on MIT and Kimber interconnects and,
I think,he agreed on the Audioquest Clear.  Incidently, we tried out
the MIT's before with my ARCs and they sounded great...but I opted for
Audioquest 'cuz the salesperson claimed MIT is great for solid-state
equipment, but less desirable for hybrid designs.  I'm using ProAC
Response speakers.  Any suggestions?  Please email as soon as possible,
thanks in advance!

  Unless the speakers were bought before Jan. 22, 1988 or they were bought 
  used, Polk should replace the tweeter for free.  All Polks come with a 
  five year warranty and that warranty should be honored at *any* authorized
  Polk dealer.  I've received warranty service for my RTA 11t's at two 
  different dealers without the benefit of having my receipt - and those
  two dealers were located roughly 300 and 500 miles away from the shop
  where I originally bought them.  If your friend is the original owner 
  and they were bought after 1/22/88 he should still be eligible for
  warranty service.

I've had a DAD5 for about a year now and have been very pleased with
it. I tested it against the Rotel965 and Arcam Alpha. I found the
Rotel was very neutral, but also very uninvolving, whilst the Arcam
was too aggressive (even though I tested it with some Slayer!!).
Overall, I preferred the Mission as it got me involved and made the
music much more enjoyable. I'm now considering adding the DAC5 so I
would be interested in auditions you do with it.  Most reviews I read
in the British press reckon that it gives improved performance, and
competes well with machines at the joint price range.

FALSE in my opinion, but yet again the last time I auditioned them was a year
ago (with Krell gear). I was not so impressed with soundstage.

That probably means that it's worth reevaluating the new Mirage 3's; maybe
some things have changed.

The latest Glass Audio (1/93) has an excellent article by Andrew Nehan
on a 40W triode amplifier.  The excellence is in that it talks a LOT
about the design decisions, and why things are done certain ways.
Much better than Joe Curcio, who may have excellent designs, but is
almost as cagey as Dave Hafler was about not explaining his designs
too well.  (Can't give away the secrets!)

The monoblock amp uses 6 6550's for 40 Class A triode watts.  The
input is based on the Hedge long-tailed cascode pair (like the
Curcio), but with cathode followers added to drive the capacitance of
3 triode-connected 6550 grids.  The current source designs are better
than Curcio's, and he shows how to use a current source to make the
cathode followers linear.  

Definitely must reading for tube amplifier homebrewers.  Well written,
well edited, with logical and readable schematics.  Just about on a
par with a good Crowhurst article.

If you had given up on Glass Audio due to the rather spotty editorial
content (ancient articles, inscrutable schematics, bad writing) in
1992, this article alone is worth the $20 a year.

I'm not really qualified to say if it's flawed or not, but I do know
that I saw some marketing glossies pushing something similar once. They
said the sound originated (in time) not from where the magnets are, but
from a point 1/2 way between the height of the edge of the cone and base
of the cone. Might have been sony. In any case, it basically meant they
put the woofer (and midrange too) on little spacers to make them poke
out the front more.

I imagine it is flawed though. I would much rather trus the design of a
speaker that had this taken into account properly when it was designed
(measured probably) than some rule of thumb which few people may agree
with!

Note also that there is a time delay from the voice coil to the cone.
Jast as with air, it takes time for the pushing and pulling to travel
thru the metal (or whatever). But it goes very fast (? 3000m/s), and
even faster still when the force is high enough to make the properties
nonlinear. The cone also suffers these effects, and that's why drivers
aren't operated at these frequencies hence crossovers, etc. And if
they are not operated at frequencies where the time delay is significant
it doesn't matter. Well, I imagine the story goes something like that.

To add my two cents.  I think the argument put forth to say it is ethical to
mailorder after previewing equipment at a local store is flawed.  The profit
margin of a big mail order house from NYC or LA is vastly different from a
locally-owned high-end shop.  Inventory costs are much higher because of
much lower volume of sales, salaries for a knowledgable sales staff who will
spend hours showing you equipment in a high rent,expensive retail space are
also much higher than a phone sales staff who will talk to you for only a
few minutes in a small office cubicle.  These people will also often have a
more limited knowledge of equipment.
Now I am talking only of locally owned high-end shops where they are
dedicated to honest service and quality of sound.  I can't defend places
like Circuit City, where you will not get knowledgable service on a bet.
The high-end shops can also be a real let down.  I went to one near my house
a few weeks ago to listen to the two Polk audio sat/sub sets ( the 3000 and
the studio 6, $800 and $400 respectively).  The salesman gave a pretty hard
sell on the 3000's ($800). They sounded pretty good, then I asked to hear
the studio 6's.  The salesman stood in front of the amp blocking my view and
switched the speakers, they sounded terrible.  He then left the sound room
for a moment and I looked at the amp.  When he set up the first demo, he put
in the tone defeat switch and turned the treble all the way down.  When he
switched to the lower priced pair of speakers he also turned off the tone
defeat switch.  I put the switch in and the speakers sounded amazingly good,
just as good as the $800 pair.
I'm sorry to go on like this, I guess I'm still upset by it.  My point is I
would love for anyone to do "unehtical" things to this buisiness.  I'm sure
the people at Polk would be thrilled with this behavior also.

Two things I've been wondering about or been annoyed by:

1) Why are there no pre-recorded metal cassettes, or no pre-recorded
   Dolby C cassettes? Every decent cassette deck for many years
   (even car decks, for crying out loud) has had metal and Dolby C
   capability. There must be some demand? Sure metal tape is expensive
   but so are CD's.

2) Why do they not "record" or "press" or "download" :) or whatever
   the appropriate term is, on both sides of a CD? Again, this would
   be more expensive, sure, but probably much less than two CD's?
   I certainly wouldn't mind flipping a CD over if I could save 
   several bucks and obtain the several other obvious advantages
   of this.

if it is the 102's about which people are talking, then putting them
inside a {paper|plastic|cardboard} sleeve makes them managable when
inserting records. not *more* managable, managable.
