  I am not sure if the manufacturer's warranty will replace the
  product with a new one. Anyway, about 3 and 1/2 years ago
  I bought a dual cassette panasonic boom box from Good Guys. At that 
  time I also bought a 3 year extended warranty from them. After 2 and 1/2
  years of operation, one of the casette heads wasn't playing in stereo.
  (i.e the sound was coming out of only one speaker). I took it to good
  guys and much to my surprise they replaced the whole unit for me. Since 
  my original boom box was discontinued model, I got the latest comparable
  model with more features.

  Note: The original problem with my boom box was so trivial, that I wouldn't
        even have taken it in if I didn't have extended warranty.

These little half-pint all in one systems seem to be all the rage these
days and the models kep changing constantly. I heard a nice Aiwa system
recently with dual cassette, CD, tuner. Some come with a CD built-in,
others have CD inputs for adding an external CD player. This is not
a bad way to go since you can buy a portable CD player and at home
run it through the system and take it with you to school/work.

I should also mention that some of the newer models incorporate
multi CD changers (3-5 CDs depending on make and model). 

You should decide what features you want, ie. do you want CD built in,
and if so do you want a changer, and then take some tapes or CDs
you are familiar with and listen to some systems.

I believe that this is the case with the Arcam transport/DAC, but I believe
that Linn simply take an analogue voltage back to control a VCO in the
transport.  This will give them long-term speed stability, but I can't see it
doing anything about jitter.  They'll still have to recover the clock from
the SPDIF data.

Deltec (DPA) have a DAC that generates a clock, and will sell you a bolt-in
conversion for your transport that clocks the transport from the DAC.  This
seems a cheap(ish) solution, rather than buying a whole new transport, and
I'm surprised it hasn't received more attention on this net.

[Note:  None of the above is to be taken as an admission that I think that
        getting rid of jitter by external clocking is any substitue for sound
        design in the first place!]

  Perhaps not human levitation, but there are areas involving what is
often referred to as paranormal phenomenon that would justify scientific
investigation.  Perhaps we have truly just begun to unlock the potential
of the human mind... but I think we're now completely off the topic of
audio equipment and I apologize.

  On the topic of cables, however, I do have a question.  I wish to
run speaker wires from my amplifier to another room.  Is there a limit
to the length of the wire before the sound is adversely affected.  I would
assume the shorter the better, but perhaps I'm out to lunch.  A
salesperson told me not go more than a certain distance (I can't remember
the number exactly) with certain qualities of wire.  If this is true,
could someone tell me what factors I should consider before installing
the wire?  Any help would be greatly appreciated.
  Thanks very much.

Oh, *now* I understand. Even though it looks like a duck, walks like a duck,

possibility, based on blind faith alone, that it's really a pterodactyl. Hmmm.

Yes, often very greatly.  When speakers are called "8 ohm", they
probably go from 4 to 60.  It's often unclear just what you should
call a given speaker.

>In the same vein: What damage could be done if you have 40 ohm

None, except for a very wierd amp.  The normal problem is reverse,
using 4 ohm speakers with an amp that is only designed for 8 ohm
speakers.  Many good speakers are 4 ohms, and apparently some amps
don't do well below 8 ohms.  Better ones will drive speakers down to 1
or 2 ohms.

>Is this just a problem of impedance matching ?

No, there's no real matching with speakers.  The primary issue is that
lower impedance speakers try to draw more current for a given voltage.
If the amp can't supply it, you get bad sound or a damaged amp.  Thus
you'll see ads talking about "high current capacity" for amps.  This
means they can deal with low impedance speakers.

Positive to positive for a 6dB per octave Xover ( which a single cap is)
BTW a tweeter is probably unnecessary for surround, rear channel high

If you mean that you use a ground spike for grounding the neutral and safety
grounds at the breaker box - surprise! That's usually the way it is on many
homes already!  Grounding to the water pipes is electrically equivalent, 
though, given good clean connections to copper, since you're just tying back
to earth via the pipes.  The only way to "fully isolate" your home from the
rest of the neighborhood would be via a separate isolation transformer for
your house, and then NOT connecting to earth ground anywhere; but this would
be an EXTREMELY dangerous thing to do, as you would no longer have a grounded
"neutral" line.   I wouldn't worry too much about ground noise from the
rest of the neighborhood, though - it is undoubtedly several orders of 
magnitude down from the noise induced on the ground within your own home.

If you're talking about grounding a given piece of equipment using a "local"
ground rod, that's always a "best practice" - assuming good connections and
a short run to ground.  (One problem with connecting equipment to pipes is
that you're never sure whether or not you've REALLY got a solid connection and
a low-loss path all the way back to "real" ground - you might even tie to a
pipe which is isolated from the supply by a section of PVC!

Date: Fri, 16 Oct 92 09:16:40 GMT

I purchased a pair of JM Lab's Micron Titane several months ago and
have been very satisfied.  They do a lot of things very well (one of
the best midranges I've heard).  However, there is virtually no deep
bass.  The -3db spec is only to 60 -- and I even have a tough time believing
that.

My mission:
To find the best subwoofer possible for under $500.  Bass quality
is really important to me.  I'm not looking for something just to boom with.

Possibilities I've considered:
1)  Audio Concept's Sub 1 ($469 parts) or LV Subwoofer ($199 parts).  Has
anyone had any experiences with these subwoofers?  I plan on
purchasing the parts kit so I will have to build the cabinet.  How
difficult is the cabinet to build and what are there any special tools
required?  How much extra is the wood itself (MDF I believe)?  How
much control does one have over the crossover?

2)  Dana Audio's Sub ($295)
"Tight bass down to 25hz."  For $295?  I'll believe it when I hear it.
Any experiences with these?  The thirty day home trial period is mighty
tempting. 

3)  Homebrew subwoofer
I've considered constructing my own subwoofer.  I'm open to any
suggestion for designs of moderately sized subs.

All comments and suggestions will be appreciated.

There was an article on this "subject" in the recording trades,  it
was Mix or Studio Sound.  The consensus from  the professional
recording engineers was that It was useful as an effect to affect a
single signal.  Basically making mono sources "stereo".  This effect
is only useful in _small_ quantities.  Used the same way one would use
an echo box or the like.

It was tested as a "global" effect for stereo mixes and it was deemed
unsuitable in this mode.

A little more fat for the fire:

When I started buying CDs, I didn't own a player;  I was borrowing a
really cheap yamaha unit, a CDx3, or something.  Although it sounded
pretty good for the money, my tape deck still tended to sound better.

I bought a pack of 10 cd rings, red things about 1/2" wide, that you
stuck to the label side of the cd.  For good.  I went through each of my
CDs (only 10 at that time) and listened to it, applied the ring, then
listened to it again.

On that player, the rings did make a difference.  Mainly a tighter mid
range and clearer highs, for whatever that is worth.  Some disks more
than others, but they all did sound better.

About a year later, I bought my CD player, a yamaha 520.  A much more
solidly built player.  I repeated the test with another ten rings, and
couldn't detect any difference this time.  Just this year, I had my CD
collection stolen (grumble, grumble), so of course the replacements did
not have rings.  Did I notice a difference in the CDs that used to have
rings.  No.

Summary:  If your player has a cheap, shaky transport (does it skip when
you slam a door) then you will probably notice a difference.  If you
move up to a player with a solid transport ( you have to bounce it
around pretty hard to get it to skip), you will probably not notice any
difference.

For those with $1000 players, forget the green pens and cd rings.  For
those with $120 players, perhaps it is worth a listen.
