Greetings. I have had moderate success in finding good local sources of
bulk cassettes. I'm interested in good quality chrome C10's and C20's for
demo work. TDK now sells a "Master Series" cassette that I've had
excellent results with. It comes in C10, 15, and 20 configurations. The
problem is that I can only find it at local record stores, sold
individually, at prices that I'm sure can be beat.

So my request is:

1. For a good priced source of brand-name cassettes (mail order?)

2. For a good priced source of bulk cassettes.

Any information would be appreciated.

Paco

The system that I described is not totally immune to this kind of
fault but it is an order of magnitude better.

Lets say that you install the system and figure that the .5 watt
tap will provide enough power to drive the phones you are using.

You will need an amp that can put out 20 watts and is one headset
shorts out you only have a drop in level of .5 watt instead of the
whole line going down.

In actuality if you the volume control as I have suggested you have a
little better isolation due to the voltage divider action of the pot.

The only two ways to measure AC current are a Hall-Effect device, and
a current transformer. 
Most current transformers are made for continious use, however they
require an ampmeter as a load (otherwise they self-distruct).  Going to
low DC voltage will require some processing, so you might as well use
an ampmeter as the readout.

CT's are rates as a ratio, 400:5 means 400 amp full load gives 5 amp
output.  This is based on a single turn (straight through) primary.
You can use multiple primary turns to alter this ratio.

Check out C&H Sales in Pasadena CA, (they have an 800 number) their
catalog lists AC ampmeters (up to 30 amp), and the transformers.  The
Electronic Engineer's Master will list CT sources also.

	I've borrowed my friend's X-26 to play around with for a while. 
There seems to be a problem with it, and it looks to me like the erase head 
may be fried.  I'm no expert at such things, so I thought I'd run it by
the net audio pros.  What happens is, when re-recording a track, it doesn't
seem to erase what was previously recorded.  Even re-recording white space
leaves a slightly softer, yet definitely present previous recording.  I 
tried this using a brand new high-bias casette, so it's not a factor of the 
bias or age of the casette.  I've tried demagnetizing to no avail.  Any 
suggestions?  Another fact just to toss across:  a person who borrowed the 
machine from my friend (not me!) "lost" the power adaptor.  Could using the 
wrong type (polarity, voltage, current) of adaptor have hurt the erase 
head?  Everything else seems to function properly. (BTW, I used "lost"
because I am wondering if the person did the damage, then conveniently "lost"
the adaptor so my friend wouldn't find out...).  Anyway, any suggestions,
expected costs to repair, etc.  would be GREATLY appreciated.  TIA!

The best possible source of information on setting up your subwoofer is
the manufacturer of the subwoofer!  Why don't you write them, describing
exactly what you want to connect it to, and asking for their advice.  In
my experience, the manufacturer will do everything in his power to make
certain that his equipment sounds as good as possible.  He certainly
doesn't want a customer flaming his speakers on rec.audio.

Apologies to everyone for posting what was meant to be private e-mail. But
my mail keeps getting bounced back to me. Could you (J. Johnston) send a
reply with an e-mail address with which I might have better luck? Thanks.
--------------------------------------------------------------------------------
J. Johnston,

Thank you for providing one of the few sound voices of reason on
rec.audio, especially in the talk about jitter. I have a request for
clarification, and a repeat of a question that came back to me as
undelivered e-mail.

I had asked whether there would be generational loss in MD or DCC
copying, specifically whether COMP(DECOMP(X)) would equal X. You
responded by saying that the compression was lossy (I was aware of
this), and I sensed an implied "So of course they can't be equal." Was I
misreading you?

It is possible to have lossy compression that does not degrade with
repeated application. To take a simple example, suppose you compress a
digital image by saving only every other line. The image will be
(imperfectly) rendered by filling in the missing lines with copies of
the previous lines. If you apply the process again, the same lines will
get saved, and the same decompressed results will be produced. After an
initial 50% loss in information, the situation will remain entirely
stable with repeated applications.

It should be possible for a lossy audio compression scheme (even though
obviously far more complex) to have the same characteristic of
preserving the information retained by a first application of the
compression. What I'd like to know is do either ATRAC or PASC have this
characteristic. It seems unlikely.


The other thing I meant to ask you was this: Do you have some way of
getting standard CD audio data into a computer (preferably a Macintosh).
CD-ROM drives that I have used don't allows audio sectors to be loaded
from a disc. Something that you wrote earlier indicated that you had the
ability to examine the audio data on a CD.

	Hello neters, are you interesed in Musical Fidelity A1 :

	I have got a Musical Fidelity A1 amplifier, for one year.
Actually, I appreciate a lot the quite good musical quality of this amplifier, 
given the price. In fact, I love my amplifier, I tried other amplifiers, 
twice the price (!) and I prefered the musical fidelity A1. I also tried the 
Musical Fidelity A200, thinking that as the A1 was so wonderfull, the A200 would
be very interessting. And I see that the A200 is less good than the A1 (!!).
This opinion, which surprised me at the begining, was confirmed by some Hi-Fi
vendors, who explain me that it is true that the A1 is an exeptional 
Quality/price ratio, so good that it is better than the A200.
but that the A1 has only one problem : it is very very FRAGILE.

A lot of vendors I saw who made the brand Musical Fidelity said me that they
stoped distributing this brand because almost all the amplifier they sold come back 
for reparation. And I heard this opinion from vendors of different stores, of town
 distant from more than 1000 km, so I think it is true. 

I have no problem with my amplifier now... But I would be glad to get the opinion
of other user of this amplifier. So, if you have a Musical Fidelity A1, if you had
some trouble with it, could you mail me to explain me WHAT SORT of trouble you get, 
How much time after buy, and was it repared ? 
If you don't have trouble, you can email me just to say me that this amplifier is
the best Quality / price ratio in the world, I will be very happy to agree with you.
And if you know this amplifier and that you found one better, 
please tell me which one ?

I am looking for a good pair of headphones, closed design if possible,
due to dorm noise from roomate's TV.  I wouldn't always be listening in a 
bad environment though, so I don't want to skimp on quality.  

Can anyone reccomend a comfortable, good sounding pair for around $100-125?

I listen to rock mostly, from Pink Floyd to Joe Satriani (guitar God), but
I'm not a bass freak.  I have a 6 changer and I use it, so I also have to
emphasize the comfort end.  I also wear glasses, and anything that presses 
on my ears eventually starts to bother me.  

There was no mentiosn (that I found) of headphones in the FAQ, so any other
helpful advice on what to look for and pay attention to in headphone design
would be most appreciated.

Thanks!

After auditioning speakers form Theil (1.2), Vandersteen (2ce), B&W (I
forget the model), Phase Tech (8.5), Klipsh (5.2), I finally found what
I was looking for.  I bought a pair of Definitive Technology BP 10. 
Under $3000, they easily are what I believe to be the best sounding
speakers one could by.  They are sweet and never harsh (at almost any
volume - depending on the amp).  Most of all, they are EXTREMELY
emotional.  I know I copying that discription from Stereo Review (yuck)
but I know of know other word that can discribe them.  I'm sure that
they are not the most accurate speakers in the market, but they can make
listening to music a totally wonderful and satisfying experience.  One
could listen to them all day without any fatigue.  My previous system
was the Cambridge Soundworks Ensemble.  The CSW are very good speakers
for their price ($500).  From what I've read and heard, they are crisp,
clean, quite flat and image very well (assuming proper placement.)  But
they, in absolutely no way can compare to the BP10s in sheer enjoyment,
volume, soundstage presence, and impact.  
I'm not much of a classical music fan (probably because I heard them
from "lesser" speakers), but now I'm hooked.  As I'm writing this
message, I'm listening to The score to Batman.  And it sounds just
wonderful.  Even with my back turned to the BP10s, I can swear that I
have real instruments playing behind me.  The imaging, huge soundstage,
clearity, and 20hertz bass extension is just phenomenal.  After
listening to other classical works, the BP10s (along with the bigger
BP20s), in my opinion are the "best" speakers one could buy under $3000
(maybe even more!)  Listen to them.

I really must take exception with your knock on those of us who make our
living in the digital world.  Having received what I believe to be a fairly
well rounded Electrical and Computer Engineering education (everything from
Circuits 1 to Op-Amp design to graduate level DSP), I have come to the
conclusion that all fields of endeavor (at least in engineering) are as 
"Hard" as we choose to make them.  

Any good Engineer/Scientist must always allow for the fact that the closer
one looks at a particular subject, the more likely he/she will need to explore
outside of their area of immediate expertise.  To imply that something is 
"simple" just indicates a relative non-familiarity with it's details.  

While I admit that at times I certainly come across lots of "no-brainers"
in the digital world,  I just as often encounter problems that require a
significant amount of creative thinking and pure hard work to solve.  I
even tackle some analog problems now and then.

To assume that your chosen field is the only one that requires any amount
real thought to accomplish anything is just plain dumb.
