Sennheiser in Germany makes Sennheiser headphones (surprise , surprise !).
Why don't you look in the Yellow Pages and find a HiFi dealer that 
carries Sennheiser and then call their service dept. regarding getting
your headphones fixed. Given current labor rates, you will probably find 
it cheaper to buy a new pair rather than getting them fixed. Good luck !

Gawd, I wish I knew. If you know of some place that can analyze it, I'll
send you a sample. It smells something like benzine or paint remover,
but "stronger". It will dissolve most plastics unlike the benzine whose
odor it resembles. It seems to have a low vapor pressure too, 'cause
it takes forever to dry; you have to wipe it off. Somewhat more like
a very thin oil than a volatile solvent. It does not smell like xylene
or toluene.

I know this doesn't help at all. The bottle just says it contains aromatic
hydrocarbon (right..) and antioxidant.

With modern solid-state amplifiers that behave essentially as pure voltage
sources, no, I don't know of any dynamic driver that presents a wierd enough
load. I've not seen any reasonable theoretical or empirical evidence advanced
to prove the case. This is not to suggest that's it's balony, it's just that
no one has advanced the case.

Aperiodic systems claim to be able to do this, but the impedance curve strongly
suggests otherwise. In an aperiodic system, the attempt is made (among other
things) to add as much mechanical and acoustical loss to the system as
possible. The problem with this approach is that the predoiminating loss in
a speaker system is the electrical losses in the voice coil, and typically the
sum total of the mechanical losses (in the driver) and the acoustical losses
(in the enclosure) are no more than 1/4 that and often an order of magnitude
less. Doubling the acoustical losses has a negligable effect on the total
system losses. An aperiodic system can reduce or eliminate the impedance
effects that would otherwise arise due to the fact that the system is a vented
cabinet, but in doing so, you've also eliminated any advantages of a vented 
cabinet.

As to the electrical vs acoustical results, the use of aperiodic designs has
profound effects on the acoustical response of the system. However, linearizing
the impedance with conjugate networks will have little effect, presuming the
system is driven from a low impedance source, as most amplifiers provide.

Hi Jeff. I've got the Boston A120's for my front and love them (plus I have
a pair of Baby Advents on the sides of the listening area for fill), then
I built some small speakers for the rear. I'm extremely pleased.

My brother bought Cambridge and he loves them. but I haven't heard them, but
I do trust his judgement (although his opinion of appropriate bass is
different from mine, so I suspect that the Cabridge might not have as 
strong of a low end as the Bostons - but I don't know that for a fact).

For the center I just bought a Design Accoustics (don't remember the model
number but it has the 6.5" woofer). And it's very nice.

Oh, here's a comment to all of you that have pro-logic but use the 
phantom mode (center) instead of an actual speaker.... GET THE CENTER
SPEAKER. I've been using my with phantom since I bought the receiver several
months ago. Than last weekend I bought the center speaker. BIG DIFF! The
surround effect is much better defined for some reason. Can anybody 
explain that?

Now I just need a bigger TV set! (19" don't cut it :-)

My girlfriend's cat was in the same room as my stereo, and decided to use
my speakers as a springboard to the window.  In the process, its hind legs
pushed in one of the tweeter domes.  To be more specific, the speakers are
Acoustic Research 98LS, and are 4 way, 4 driver.  The two tweeters are a
dual-dome mid/high range driver.  The 38 mm hemispheric mid-range tweeter
that used to be a dome is now a kind-of flat squashed thing.  The speakers
still sound fine, and they equalize flat.  However, every once in a while,
the receiver (a "The Carver Receiver") cuts out for about 10 seconds
(presumably it's the speaker protection circuits kicking in.  I don't play
the system very loud at all, so the problem can not be because I am
over-driving the speakers).  Do any of you have any advice?  Should I worry,
or are the speakers just fine (if a little funny looking)?

Also, in the process, the cat's claws put a few scratches on the
enclosure.  Do any of you know how I can go about removing them?  I have
heard that there are some kind of pens that you can use on scratched
furniture.  Do any of you know of such a thing and if so, how well do they
work?

   For one thing, I've never really found the need for noise reduction on a
HiFi deck. I could be wrong because I haven't paid attention. The quality
and frequency response is very good because of the head:tape speed. The
speed of the tape (i.e. SP or EP) doesn't make much difference at all.

There you go guys!  Trying to play on the emotions of Audiophiles.

Once you *say* there is a better cable and don't come through with a
manufactureable product you will have Audiophiles wandering the
streets bumping into buildings searching for the ultimate speaker
interconnect.

Some time ago I suggested the "perfect" speaker interconnect.  I will
hear and now offer that product for sale!

It's a damn shame I can't post this to rec.audio.high-end....Or maybe
it's good.

The price, and that is what is of prime concern,  is open ended.
First of all you have to pay me to come to your listening room and
evalueate your systems suitablilty for these intersonnect.

The sucessful applicant will have to pass a strict guideline set my
me and no one else.

The fee for this visit is $150 per hour travel time, on site and
return to base time.  Not included is plane fare, first class.  Meals
and any other expenses.  Minimum $15,000.

After I have accepted your system I will return to my office where I
will custom design the interconnects. 

Length of the interconnect is flexiable and no federal, state city or
county permits are required forthe interconnect system installation.

My detailed installation drawings and instructions should be sufficent
for any plumbing contractor to follow for sucessful installation.
The cost of materials and installation labor is extra.  Plan for a
total fee here of $10,000 and I specify the contractor.....

The design phase will take as long as it needs and cost $250 per hour.
Minimum $2,500.

The interconnect system will be guaranteed to be miminum loss for the
scientific freeks, and have a testable frequency response to not less
than 1 mHz.  

If a response effect is desired tuning stubs, err I mean system interconnect
tweeks can be designed for and will be considered at a fee of $5,000.

While the above offer only adds up to (with tweek option) a mere
$32,500 I can deliver!  The $10m cables, while really tempting, I
believe the "manufacturer" will be unable to deliver based on
manufacturability, fereral, state, city and county restrictions,
etc, etc, etc......

Don't call me at the phone number listed in my .signature for this
offer.  Please Email  your request.  Be prepaired to place $50,000
in my personal checking accound as a show of good faity and the fact
that you are a true believer.......

Since this offer is contingent on me and my time to personally
size up the situation this offer is limited.  I figure that I can only
deal with one trip a month so 12 units a year is it!

Any returns to personally tweek or inspect the system installation
will be based on the trip minimum fee of $15,000.....

This is because of general, widespread dissatisfaction with the

The shift will stop if Bush is reelected.  It will also stop if Clinton

Norman - I'm old enough to remember when the cassette first came on the
scene.  It was touted as portable recorder, and it was never thought of
as a serious music device.

The American music appetite seemed to want a way to put music in their
cars.   The 45 rpm players for the cars never caught on, but they were
available as a factory installed option from Chrysler corporation.

Then the 4-tracks entered the scene.  These were an adaptation of the
cartridge format used in radio - which was an adaptation of the
original cartridge design used for background music systems.

Then Lear came up with the 8-track design.  Made players cheaper and
tapes cheaper.  

At that time cassettes were just starting to come into use in the
home, and pre-recorded cassettes were just coming in to use.

In those days the 8-tracks sounded better.

But CHEAP wasn't the operative word.  Convenience was.

And pre-recorded cassettes cost more than the LP's.   The cassette
prices never really lowered, but the LP prices went up.

The oil embargo of the late 70's/early 80's was a good reason for the
LP manufacturers to raise their list prices $1 even though the cost
increase was just a few cents.  

I have never seen a decrease in prices, and when there was a reason
(however slim) to raise prices, it was done, and when the reasons went
away, the price never lowered.  Laser disks are about the only consumer
medium that incurs a higher shipping cost than LPs.  So that is another
reason they stayed high.  Even reducing the plastic content to save on
manufacturing and shipping didn't help enough.

It was only after the cassette took over 1/2 the market, and the rising
price of the LP that cassettes became cheaper than disks.

It wasn't cheap that made cassettes popular, it was that the popularity
of cassettes made them cheap.
