Subject: Need recommendations (turntable, laserdisc) & info
Date: 15 Apr 92 21:18:35 GMT
Organization: Purdue University Engineering Computer Network

My brother, who is in possession of a large number of records,
is interested in buying a good turntable.  He asked me for 
suggestions; unfortunately, I have never been in the market
for a high quality turntable (I don't have enough records to 
justify it).  I told him I'd heard glowing reviews of Linn
products, and suggested he find a dealer who had such things.

His local dealer (he's in the not-such-a-metropolis of Normal,
Illinois) seems giddy over turntables made by a British company
called Revolver (coincidentally , this dealer carries 
Revolver :-) which I haven't heard of as far as I can recall.

Can anyone comment on these?  A significant attraction (for
my brother) is that they make both a standard (33/45 rpm) and
a dedicated 78 rpm turntable (he's contemplating buying both).
How does Revolver compare with the "audiophile" favorites:
is it even in the same league?  I have my doubts, as this store
seems geared toward the Onkyo/Nakamichi/Klipsch crowd.  Is
the difference worth whatever additional cost may be involved
to buy a Linn or what-have-you?  Does Linn or someone of that sort
make a table which can play 78's?  Is there any merit in buying 
a separate turntable to accomodate 78's (other than avoiding
the need to change needles (and speed control :-) when playing
them)?

Diverging somewhat from audio, can anyone suggest a few good
laser disc machines?  Here I am even more ignorant (not a video
type myself) and can offer even less advice.  These would not
necessarily have to be the kind which play all varieties of
optical disc (although let's not exclude those either if the
picture and sound are sufficiently good).

Altogether unrelated: does anyone know the phone number for
Proton?


Thanks!

I had a pair of old (like 15 years, maybe) KLH speakers that I shredded with
my synthesizer, by accident (of course).  The cones literally fell apart.  A
certain example of foam rot if I've ever seen one.

I replaced them with Infinity RS-3001s (with plastic components ...) which are
vastly, vastly superior.

Those KLHs lasted, though, about fifteen years before I killed 'em with a
digital synth with 22 bit dacs and one hell of a fat patch !

Hi there everybody,

	I'm just curious if anyone has ever heard of ACOUSTIC speakers.  I
don't mean the adjective "acoustic," but rather the name brand ACOUSTIC.  If
so, how are their speakers?  How much do they cost?  Any information would be
appreciated -- either e-mail me or post replies.  Thanx in advance.

What's wrong with it is "deviation from the original waveform" has NO meaning
until you specify how this deviation is to be measured.  There are literally
an uncountably infinite number of ways deviation could be measured.

E.g., you could measure the mean-square-error, the mean-cubed-error,
the mean-x-error where x is any real number used as a power.  You could also 
measure the average maximum deviation in a second, maximum deviation in a
millisecond, etc.  (And that doesn't even BEGIN to exhaust the possibilities.)

As you would expect, some ways of measuring
deviation are more relevant to what the human ear-and-brain hears than others.
That is to say, some kinds of distortion are more meaningful to audio
interests than others.  But what kinds of audio distortion are the most impor-
tant I cannot say.  It's probably very imperfectly understood by anybody, 
though of course many understand it better than I do.

Why did you opt for a Linn when the Victrola had such a warmth and
true-to life quality?  I think you could substantially improve the
sound of your system by substituting a Victrola for the Linn.

  If you have a Service Merchandise in your area, check out to see

  These have twin 4" (or so) drivers with a single tweeter in the

The Victrola can be made to sound just as good as the Linn by simply
tying a knot in the horn of the Vic. The type of knot will, of course,
affect the coloration of the sound; for example, a clove hitch will produce
a nice warming effect, while a hangman's knot will function as a dynamic
range compression filter (sorta like half a dbx box). My favorite,
however, is the slip knot. It allows the musical nuances to "slip"
through.

Here's a surround question for you folks:

Some front speakers project a 3D image (a bit behind the speakers as
well).  Another type projects a very flat, closer to 2D image that may
be a bit more accurate in frequency response; this type of speaker
also seems to have an image which begins from the speaker.

What would be better for a surround sound Prologic system?  The
question is whether the 3D image of the former speakers interfere with
the Dolby Prologic decoders intentioned image after you add the center
channel and rear channels and subwoofer.

In case you're wondering, the B&W 804, Martin Logan Sequel (when pointed
at you), and the Khorn fall into the former category.  The Thiel 2.2,
Vandersteen 2, and Kef 104 fall into the latter.  (or at least to my
humble ears ;-)

It seems like a fundamental question I need answered before deciding on
anything...especially since I'd like to set up a surround system in the
near future...

Me too.  While I might agree with the original writers subjective
experience (didn't read it all-too long, to drivelish), the

resolving -60 dB sine waves without distortion hartks back to
last summer's bad ole days of the "harmonics of sine waves". Ugh.

This attitude is just as closed-minded.  Certainly, digital reproduction
has a long way to go, just as it has clearly improved amazingly over the
past eight years.  Attributing all the subjective liking for analog
to "euphonic distortions" doesn't cut it.  The fact that these
euphonic distortions _just happen to_ be the exact reverse of what's
lost in recording / mastering / storage / etc. is too great a 
coincidence.  Sort of a lucky encode-decode function that 
never requires engineering and planning.

Where, oh where did moderation, reason, and the quest for 
answers ever go?

Sorry to pick on your post.  The original certainly deserved
a curt response.  I just don't think that the perceptions
of the author were as off base as his technical conclusions.

I've heard one and modified it. The Pioneer 1-bit machines sound ok. Not
great, but not fatiguing either. In fact, they're pretty dynamic and
vocals sound natural. I suppose the turntable eliminates the need for
Navcom rings, but the 7700 is also otherwise better built than its
cheaper brothers (4700, 5700, 6700).

Problems:
1. No high end. 2. mediocre soundstage and seperation 3. fair detail.
4. L,R channel outputs share cheap dual op-amp with +/- 6v rails.
5. Unbypassed electrolytic DC-blocking caps.

Solutions:
Replace the opamp with a good dual like the LT1122. Put some MIT bypass
caps on the dc-blocking caps and the power supply electrolytics.

Futures:
Experiment with the power supply bypasses around the DAC. Try MIT's or
Mica's. I also tried replacing the ceramic 39pf caps in the low-pass
output filter with Mallory 'styrenes - turned out a little bright
though. You really have to be careful on parts selection or else the
basic musicality of the machine disappears.

I bought a 5700 to play with myself ($139), but ran out of patience
finding the right mix of modifications. Appearantly, Musical Concepts
has, and is selling modified machines.
