What's the consensus on CD player lens cleaners?  I believe in good
maintenance, but I'm hesitant to put a spinning brush in my player.
I never use "home" VCR head cleaners (I have it professionally cleaned),
and only clean my computer disk drives when there's an error (i.e., never).  
Am I being too shy about the lens cleaners?

Didn't sony or somebody have a personal digital cartridge system
out a few years back?  I seem remember these things lying around
at K-marts, the cartridges each held one song (usually a teeny-
bopper mega-single) and cost about $3. They probably used data
compression algorithms

I just got a 325 (same box plus remote) for that price, at Sony Sound Center

Can't say much about DCC or MD, but the subject has been discussed at
various times as to making DAT copies (or CD to DAT, etc.)

The limiting factor is the SCMS copy protection/inhibit codes.  In the
past it has been discussed that the simplest thing would be to run the
digital signal (from the CD or anothe DAT machine) through a "black box"
that would allow you to reset the SCMS copy code bits (there are 2)
to whatever code you want.  The black box apparently wouldn't
be too uch more than some digital buffers with enough smarts to
determine the framing of the digital signal to sync itself with
each frame and then a pair of switches could be used to force the
SCMS copy code bits into any state you wanted.

Is such a device legal, probably not, do they exist..probably,
would designing and publishing the details as to how to build your
own be illegal...I think not.   Much like this has been done with
video "enhancer" black boxes which provide means to defeat the
signal spikes that some video makers put on their prerecorded
videos to fool VCRs into setting the automatic gain control
at a low level which results in a poor reproduction.

Now as to the legality of such equipmen, my understanding is it is OK
for "professional audio folks," but not the common riffraf audiophile :-)
Of course the determination of who is or isn't a pro has never been
tested in any court as far as I know.

From: marc@dwp.la.ca.us (MarcHall 4735)
Date: 15 Dec 92 01:57:05 GMT
Organization: L.A. Dept. of Water & Power


  I have a 37 foot sailboat in which I am currently in the process of acquiring and installing
a sound system. One requirement for the system is that it can be driven by the 12VDC supply on
the boat so I have already purchased a auto Kenwood CD Player and a SoundDesign 30 W per channel,
4 channel amplifier.

  I am looking for a set of speakers to place in the main cabin area. Three sets I have listened to
at various local outlets include

	1 - Polk Audio - small Triangular shaped speakers selling for $200/pair.

        2 - Bose 3 component system including 2 very small triangular shaped speakers and a 
	    sub-woofer/woofer component that is about the size of a large shoebox. Priced at
	    around $400 for the system.
	    
        3 - Bose 3 component system similiar to 2 above but the sub-woofer/woofer component is
            about 7"Wx14"Hx19". The other two components each consist of 2 small speakers one
            of which is stationary when mounted and the other which can rotate (90 deg ??) in one
	    direction. Retails for under $700.


  I like the sound of the third system the best but placement of the sub-woofer/woofer component would
be a lot easier if it was a couple of inches less tall. 

  The Polk audio sounded decent but not as good as the $700 Bose but I listened to the these at a 
different retail outlets.

  I live on the boat year-round so I am not too concerned about the effects of the humidity on the
components -- I think I will get a lot of use out them before they need to be replaced.

  
  Any suggestions on any of the above speaker systems or others that I might want to consider.
I don't mind mounting speakers like the small Bose components or the Polk Audio's to the boats
bulkheads but I am not very willing to start cutting big circular holes into the teak to install
the normal flush mount auto speakers.

  I am also looking for a set of speakers to be mounted out in the cockpit. If permantely mounted
these would have to be somewhat waterproof as I wash down the boat at least on a weekly basis.
The cockpit is fairly dry when underway although some saltwater spray will likely reach the
speakers. The local Marine Store sells a set of flush-mount Jensens and Bose has a small 
self-enclosed set of speakers that are apparently somewhat waterproof.

  Any suggestions for these ?


  Thanks

because of another discussion going on, I just happen to have been thinking
about the VMPS line. There are three subs from about $280, $325, $450, these
prices may be old. I've auditioned the middle size "Original Sub" and liked
it alot, so did Stereophile. Good bang for buck. Kits, need to be assembled
but cabinet work is already completed. Available direct or through A&S Speakers.

They both advertize in the back of Audio I think.

"Quality" is not "information content."

You couldn't call it misleading.

BTW, I went back up to Hi-Fi Sales in Mesa this afternoon,
because they've been doing ads for the Technics DCC
including a promo where you get "$200" worth of "software"
free if you buy the deck.

Problem is, they've stickered it at $898, and for some
reason they don't have any "software" in the store, so they
refuse to demo the thing.  Their floor model isn't even
plugged in.

Instead, I switched to plan B and got a Yamaha MRX-101
multifunction remote.  No more trying to remember the eight
things I have to do to turn all that crap on just to see
Koppel when I get home late...

Subject: HELP!  Sony ES 5-disc player busted
Date: 17 Dec 92 00:33:26 GMT
Distribution: rec
Organization: M.I.T. Media Laboratory

Greetings!

  I've had a Sony C-85ES 5-disc CD player for a bit over two years
now, and I've been quite happy with it.  However, the other day, it
spontaneously broke.

  The problem is this:  you put in a disc, hit load, and the player
loads the disc normally, right up until the point when the disc is
supposed to start spinning.  Then, the motor seems to spin, but the
disc never spins up.  After a few seconds, the player decides
there's no disc in that slot, and tries the next one.  After trying
all five trays, it gives up.

  The machine's under warranty, so I should just get it fixed,
right?  Well, two things interfere with that plan:

  1)  I can't find the damned receipt.  I have found, in the last
two days, every receipt for every piece of consumer and computer
electronics that I own, and even some for stuff I sold/discarded
years ago.  But, no receipt for the player.

  2)  I have ANOTHER ES player, which has the same problem.  It's
four years old, and is therefore out of warranty.

  So, what I'd like to know is this: What's the matter with it, and
how much does it cost to fix?  I took the old player apart, and it
seems that what's happening is that the motor is spinning, but the
hub which is attached to the motor's spindle is not spinning along
with it.  With the player open, I was sometimes able to nudge the
disc to get it to start, but this is clearly unacceptable.  This
seems like it should be easy to fix, but I expect that they'll
probably try to bill me for a whole new mechanism.

  The reason I ask about cost is twofold:  if I can't find my
receipt, I'm going to be stuck paying for the repair.  And, even if
I do find it, I'd like to get the old one fixed and give it to my
parents.  But, if I could buy them an inexpensive new single-disc
player for something comparable to the repair price, I won't bother.

Thanks for any help!

For a better more involving sound.  Its an engineering fact of life that
the parts budget and development effort for a $13,000 D to A (digital to
analog) converter will result in better sound than a $800 Nakamichi.  That
doesn't address the larger question of if ANY mere stereo component can
be "worth" $13k.  Like $5000 wrist watchs its a luxary item for the rich
and self indulgent.

Why? Why not use the right woofer for the application (which might well be
a Vifa woofer)? Why not define what the performance you expect from the
system should be, then derive the necessary woofer paramters from that,
then find a woofer that most closely matches those parameters.

Doing it your way is like have an answer then trying to fabricate a
suitable question for it.

I've tested 'em both and if there was any difference (and it's NOT
