Summary:  dad owns one, doesn't use, what is it worth?

he hasn't used it for years but it did work when he bought
**new** equipment some 15 years ago ;) .  he also has an 
accompanying marantz amp that needs a new power supply
for one channel (this is not a tube amp however).  since
i have net access, i may as well tap you for your
estimates on the 10-B.  I know I have seen ads in hi fi
magazines and in SpeakerBuilder for people who buy such
equipment.  Thoughts, comments, and interested parties...?

that's about the best way i can describe it.  my B77 makes grunting noises
as the reels rotate.  sigh.  examination shows that the source is the hubs
and how the tight reels are on them.  I have the aluminum hubs which click
into the "correct" position, unlike most other hubs which allow you to
really tighten the reel onto hub.

this does not seem to be related to tape winding. neither the akai nor the
tascam make this noise.

clues?

  I have a Moscode 150 running thru an Audible Illusions preamp. I
  purchased it after listening to some Hafler, Adcom, NAD and Conrad- 
  Johnson amps thru a tube and solid state preamp a few years back.
  As I recall the Hafler and Adcom sounded a little thin, the NAD
  a little warmer, the CJ nice and soft, and the Moscode a nice
  middle ground between the solid state and tube gear. The Moscode 
  and CJ imaged better than the other gear when listening thru
  some Spica TC-50's.  

  Don't know about the Moscode preamp as I've never heard one, but
  I seem to recall that the 'sweet' Moscode sound tends to be a
  bit overdone when using both components.

  I put some in the amp four or five years ago and haven't had any
  problems ever. The Moscode like the Counterpoint SA100? is a hybrid
  design with tube input/MOSFET output, so the tubes aren't stressed
  like the big, hot, glowing power tubes on real tube amps. I recall
  that the Moscode uses 12AX7's (?) and 6DJ8's, which are pretty common
  and not expensive.

  Don't know about the preamp but I think the amp is worth $200, but it's 
  always best to listen before buying. When I was putting my small system 
  together I wanted the best midrange and imaging for my money and the
  Moscode fit right in. I suspect that they won't be at their best 
  driving a difficult load at high volume, and the 300 had a reputation
  for flabby bass, but with my Spica's I wouldn't know.

So now we know that you're not an Audiophile or Golden

All you need is a good CD player and a good pair of headphones.  By
usind direct conparison you can easily tell the differences between
speakers, amplifiers, speaker wires and YES EVEN connectors!

All you have to do is _trust_ that the CD player and 'phones are very

I won't touch the golden ears flame with YOUR hands!  :-)  I do
believe that Audiophiles become very acoustomed to what they
hear.  That ear training will allow them to hear differences in other
systems and components but the training is slanted in favor of their
current set-up.  So yes "they" can hear a difference that may not be
measurable with common instruments.  So if I go out on a limb here I
just might say that the serious listening of Audiophiles doesn't
concern it's self with _accuracy_ per say..........I don't really have
a problem with that fact.....There I've said it! AHHHHHHHHHHH!!!!!!!
I'm a dead man......

"....Shields Up!...."

I do believe that extensive in depth scientific testing with
sophisticated measurement equipment would be able to define, in
engineering terms the subtle effects that are heard.

Sure,  look over the specs.  If you don't like them or don't see a
value in the cost then don't buy!  That's  your freedom speaking!

The hard core types will totally dismiss yours and my comments.  I
wish I had the time and money to do the necessary testing to determine
just exactally what the deal was once and for all!  But those engineers 
and scientists how may be able to are uninterested!  And the audiophiles
know they are right so they don't *need* the proof.

Have a nice day!

Give me the exact internal dimensions  of the box and I will run it on
LEAP.

Also choose the low end response characteristic that you want.  I will
have to choose the driver from my LEAP transducer libraries for a
driver that fits the box....

If you must choose the driver then choose a driver who's equivalent box
volume (Vas) is equal to or less than the actual box volume.

The Grado uses dynamic drivers.  They do not use a tube amp (or any
other amp) to provide voltage and impedance matching.  They're rated
at 40 Ohms (nominal) and require a reasonably strong source to drive
them properly.

Summary: Need info about using a one-source passive preamp (pot-in-a-box)
Originator: tjk@csd4.csd.uwm.edu

Hi all -
	a friend of mine mentioned that he had heard of a company which sells
high-quality potentiometers and stepped attenuators installed in a nice-looking
chassis.  It was basically a pot, two input RCA jacks and two outputs --
very simple.  I think they were made to spec, so you could tell them what kind
of pot and what type of RCA jacks to use (wiring, etc, I suppose).  The main
feature, though, was that the chassis was well-constructed and shielded.
Does anyone know of this company?  Since I only use CD as a
source (sorry, vinylites), and I currently drive my Aragon amp directly
through my CD player's variable outputs, I'd like to experiment with this
"passive" preamp approach.  I think the quality of the attenuation will be
much better than the cheap op-amp which is in my NAD 5000 CD player.

	Also, how do you know if your line-source impedance is "compatible"
with the input impedance of your amp?  I think the CD's output is 120 ohms,
and the amp input is 22 kilohms.  Do they need to be the same?  As different
as possible?  I thought that larger differences of impedance from one
end of a circuit to the other meant greater susceptability to interference.
How about a good (layman's) reference on electronics/theory of this type?

As always, thanks in advance...

I don't own a DAT (yet), but I have a couple of friends who
work in Jingle Studios, and they have tried out several 
machines...

>From their stories of problems, I have decided to NOT buy
DAT until 'bugs' are ironed out.

What they tell me is that if you go for a top priced PRO 
deck, you generally get great recordings, with no problems.

With the Cheaper Pro/SemiPro/Consumer decks, they say it is
a crap shoot - a rigged against you crap shoot.  I got so
fed up with their list of bad makes and models that I stopped
paying attention to which ones they tried...

The worst I have heard is that they made a tape on the machine
in their studio, send it off to the client, who sent them back
their 'blank' tape.  When they tested the tape to see if it was
truly blank, it played just fine on the machine it was recorded on,
but had significant dropout on a different deck, and failed to play
altogether on another deck.

I haven't heard of dropout problems on the same deck the recording
was made on, but their best guess is that the DAT format isn't really
standardized, or that tracking is not the same on all decks.

This may be similar to the problem that Consumer level critics site
Nakamachi with, where their 'better sound' comes from an exclusive
'tracking' of the tape, so that tapes made on a Nakamichi will sound
great on another Nakamachi, but not so great on NON-Nakamachi.

Tracking problems on digital recordings don't really make sense.  The
'skip' phenomena experienced with CD's sometimes is due to the fact
that the data is corrupted (bad disk) or unreadable (moisture on lens,
fleck on disk, etc) and the laser beam does not get proper tracking
direction.  I would expect with digital recording, that you would 
generally get all-or-nothing from it.  An inability to track the CD
or DAT tape would result in no sound at all.  Dropout, I would think,
would be a result of bad D/A conversion.  Unlike standard audio tape,
where tape saturation can be inconsistant, and dropout can occur from
a loss or lack of audio information - with digital, the machine either
CAN or it CANNOT read the data.  There is no way it is going to mistake a 
5 for a 3 and play 'less' that what was originally recorded.

Howdy -

I've been asked by my sister in law to determine what the best set of stereo 
headphones available are - with price being _no_object_ (must be nice, I know).  
I'm sure the answer isn't cut-and-dried, but I'd appreciate the opinions of 
anyone willing to give them.  Just assume that these headphones would be a part 
of your theoretical "dream system" - absolutely no holds barred.  Oh yeah - 
wireless headphones would be nice, but only if audio degredation is _minute_ (if 
that's possible).

Hi Folks!


My two cents to the Golden Ear discussion.

My opinion is that it's difficult to hear that a system is better, but fairly
easy to tell that a system is worse.  It's all in getting used to a better
system and training your ears.

I found this out when I was buying my new CD player. At first I hardly heard any
difference between them. After two times one hour listening, I was very able to
tell the difference. Believe it or not!

I just got an older Pioneer PL-A35 Turntable.  I hope to get it running well.
It is belt drive, with a standard shaded-pole motor.  The old belt is limp and
won't even stay on, so I have to replace that first thing.  I put a long
rubber band on for fun and it worked, so I think that the turntable itself is
fine.  Let me ask about belts first.

I measured the limp belt.  It was 26" circumference.  I used string to
measure the belt path and measured approx. 25.5".  There is a standard
23.6" replacement belt and a standard 25" replacement belt in the MCM catalog.
MCM is a cheap replacement parts dealer who doesn't speak high-end.

A)	Should I buy a standard replacement belt?

B)	Should I buy a Pioneer-brand replacement belt?

C)	Should I buy a specific third-party replacement belt?

D)	What size is right?

E)	How do you judge a better/worse belt?

Now on to the second question group.  I want to adjust cartridge
position, tonearm height, tracking force, anti-skate, etc.

F)	Is there a good reference on the subject of setting
	up a turntable for best sound?  Book?  Owner's manual?
	Archived text file?  Magazine Article?

Finally, let me get to the cartridge.  The cartridge is an abused 
Shure M93 with an 8X stylus.  I keep hearing that the cheaper Grado 
cartridge is a good value and a	very musical cartridge for mid-fi.  

G)	Can anyone recommend anything else in the under $75 range, 
	or is the Grado still a good value?

H)	Should I just replace the stylus and keep the M93 for now?

I)	Where do you recommend buying belts, cartridges, etc, in the USA?
	If you couldn't guess, I'm cheap, and hate wasting money.

Thanks to everyone for suggestions, ideas, opinions, etc.  Please reply
directly.  I will send summaries to anyone who asks.  I will also post a
summary if enough people are interested.

> Should components be left on all the time?  

If after reading the various wise contributions on this topic you are
uncertain I suggest a compromise.  In Winter don't worry about the cost of
leaving gear on all the time.  The waste heat will just mean that you need
less input from other heating sources.  Those you mentioned thermal cycling
will be happy because the temperature changes on warming up will be
greatest in winter.  In Summer turn them on as required.  What do I do?  I
leave my solidstate power amp (woofers only) on all the time but with the
speakers relays open.  One channel is noisy for a while until it warms up. 
Probably some fault due to being home-made but it behaves when warm.  The
rest of my amplification is valves so I turn them on as required to
maintain long life.  The preamp has a slow turnon cycle built into the
power supply.  Moving-parts equipment stays off till needed.
