Have you tried spackle? Also, try sanding with the grain using 400 grit paper 
and finishing with several coats of polyurethane.

I just got a Kenwood 6+1 CD changer.  The model #is ??-?6640 and I
like it alot.  I haven't used a carosel changer, but I looked at both
types of players and decided on the magazine type player.  I can put
6 in the magazine, and one in a normal tray. this allows me to play
a CD in the tray while changing the ones in the magazine or vice versa
so I can constantly play a cd while changing my choice of music. Some
of carosels let you change 4 while playing 1 so it's the same type of
deal.

The noise of the changer is kind of annoying, but nothing that really
bothers me.  

Some advantages that I saw in the magazine type cd player.
1: I can get another magazine and switch 6 more with out having to 
spend 5 minutes sitting in front of the thing.  Just pop one out and
put the next in.

2: Since I have various types of music Rap, Alternative, Classical,
classic rock and top 40.  I will get a few more magazines and store my
music by my most lisened to in each catagory.  I can then store my
cd's in the magazine and never touch them again.

3: on each magazine, I can program my most listened to songs for each
magazine.

To me these are major benifits since I hate having to take a cd out,
put it away, get another cd, put it in the player etc. 

Just my .02.

I think the fact that CDs provide higher fidelity will insure that

Discs offer random-access, while tapes require rewinding/fast-forwarding.
Discs are more durable (the read/write head doesn't touch them, and
they aren't susceptable to magnetic fields).

As for MDs vs. CDs, it is true that MDs have inferior sound, but in
many situations, far more noise is added by the earphones or the
surrounding environment than the compression algorithm.  Also, if
MDs have jackets like 3.5" floppy disks (as I've heard), then you
won't need to keep them in their cases.  I estimate that you could
then fit 12 MDs in the space of one CD.  If you only like 1/3 of the
songs in your CD collection, then copying them to MD will result in
a 36:1 space-savings.  I find this exciting!

Really?  MD recorders are being introduced at $700.  Where can I get
a DAT recorder for that price?

On the set I owned, I chose the oak trim with the white cloth. The
cloth is actually a VERY light gray. Given the size of the speaker,
and the typical placement (at least 3 feet from the back wall), I
felt the black would be too oppressive and would make the room feel
too small.

The speakers are fairly stable on the stands; I don't think they'd
tip over easily. Beware that they are much easier to damage from the
back, and consider that during the placement (in my case, with 3 kids
and a dog, it was a consideration). You may find that the best location
for optimal sound is a poor location for appearance or the traffic
patterns in the room. Magnapan suggests you may want two locations:
one for casual listening (and appearance) and one for critical
listening. This is the approach that I used; you need to be careful
when moving the speakers to hold them near the base to avoid strain
on the stands.

They stand perpendicular.

They are mirror images, but not dedicated L/R. Some people prefer
to place the tweeters to the inside (toward the middle) and some
prefer to place them on the outside. Your choice...

No?  Well, I know that some CD players spec a minimum input impedance
that they will drive.  CD players have fairly high output impendaces.
Use el-cheapo or high capacitance interconnect with a high Zsource and a
high Zin amp and the highs might just go right thru the dielectric not making
it to your amp!

I just had a great idea.  I don't work for Phillips.  I don't like DCC. 
I hope it dies.  *IDEA*  Why don't I kill it?

Heck, if they can lie and say it is equal to CD quality, I'll tell all
my friends that it doesn't work, eats tapes, takes too much electricity,
and has a yearly renewal fee.  50% of the purchase cost goes to the
record companies, 1% goes to the Jimmy Fund (I want to gain
creditibility so they believe me).  DCC blank tapes are $10 now but will
go up to $25 each in the required 10 pack you must buy in a year (if
they ask why I'll say blank tape royalty tax).

I'll say it can't reproduce classical music (it plays sine waves
instead, due to its extreme dynamic range); after 50 plays, it won't
read your tapes anymore, making you think the unit needs repairs (when
really the repair people hit a switch on the machine, charge you 80
bucks, and 50% of that money goes toward the renewal fee that I
mentioned before).

I won't forget to mention DCC is an insult to humans by saying it is CD
quality when really the linear audio tracks of a VHS VCR has better
quality.  It also makes dogs go deaf since they put in a tone slightly
out of human hearing (copy protection), but for dogs, too bad.  (One
good benefit of the copy protection is that it will clear your home of
rats, and other rodents.)

I'll say you can't make copies, because the way it works is, there is
digital inhibit, which sometimes doesn't work since the way PASC (see,
I'm getting all the terms they've heard in there) decompresses,
sometimes it changes from copy protection to the sound much like that of
a cow mooing.  But the converse is that analog copies get confused with
that cow sound, thus preventing analog copies either.  And how could I
honestly recommend a format that won't let them do home taping onto the
tapes which you already pay a blank tape royalty tax on.  (Just WAIT
'till I write my Anti-royalty tax letter!).

I could go on, and another time I will.  This is fun.  Don't just hate
DCC, kill it yourself.  If you like my ideas and want more, Email me
$24.95 and I'll send you a complete package.  If you hate it, flame me.

But either way, have a great holidays.

	i recently acquired a somewhat peculiar CD `moodfood'
by the group `moodswings'. this was a pure guess, the CD turns
out to be the atmospheric style of new age music; some singing/vocals,
(chrissie hynde), some guitar (jeff beck) and mostly synthesiser-like music.
what puzzled me was the proud statement that ``This album was recorded,
mixed, and edited using analogue tape and sequential circuits technology.''
(the CD master was done through the sonic solutions system.)

	is this some kind of perverse pride in doing things the hard way?
or were they trying, at least for LP buyers, to give people the opportunity
to get a pure analog processing path? and what can this mean for synthesised music?
(actually, i may be wrong here; there are no credits for synthesiser but there
are for piano and for ``3d sound effects and "Space Surfing"'', whatever that is.
it sure as hell sounds like a synthesiser but could just be processed.)
and what is 'sequential circuits technology'?

Sir,
   In response to you request for carver info I have the following
to offer:
 
I personally own a Carver 1090 integrated amp ($600) with his
Sonic Holography circuit.
 
I really liked the way Carver's Amps sound i listened to NAD,
Adcom, B&K, Hafler, Denon, Yamaha, and Hardon Karmon and a few
others.
I felt that under $1000, Carver was the best deal.
I thought his amps had a "warm" spatial sound, and his holographic
circuit (if you have a good room set up properly) sounds really
nice. I listen to it through a pair of Paradigm 7se MkII's that
i have tweeked out to the max. i carted the integrated amp around
and listened to 30 pairs of speakers and nothing under $1000
sounded better (to me...) than the paradigms with this amp.
i set my spending limit at $1100 or so for the amp/speaker
combo, and i still get a lot of "slack Jawed" reactions from
friends when i crank it up. I keep it in a customized cabinet
with a cooling fan built into the back for those long parties.

A few things to note: The pre-amp section of this amp is not
the greatest, if you leave the tuner on, you can pick up cross-
talk on all of the other input channels except the "CD-Direct"
input which bypasses all of that. I borrowed a fiends adcom
GFP-565 preamp and ran it through the preamp inputs and man,
what a difference. (of course that is a $700 preamp)
you will also get crosstalk from phono and tape (it is only          
noticable with headphones and when the volume is cranked
and you have no other sound playing)
 
If you only play one source at a time, you should have no problem.
so my final recommendation is :thumbs-up Buy Bob!
if you can afford it, get one of his better separate power amp
pre-amp deals.

This is a repost (sort-of). I forgot to mention that the buyer pays for
the shipping.

Hi folks.

I am selling my NAD 5000 CD Player. It's a single-box British designed
player. Recommended by Stereophile (Class D, October 1992).

It has all the common features that any good CD player has. But it also
has a very nice variable output and you can remote control its volumn. I
found that connecting the variable output directly to my power-amp to be
worthwhile when I don't need any balance control. Without going through
my pre-amp, the sound is much more transparent. (Mind you, I have a very
good pre-amp - PS Audio 5.0 - so it's not saying my pre-amp is bad.)
Stereophile said that the variable output is worse than the fixed-level
output. I agree. (Yes, I connected both the variable and fixed-level
outputs to my pre-amp and tested them.) But it will take a pretty
discriminating pair of ears to detect the difference.

I also compared the sound of this machine to Rotel 955AX. My NAD5000 has
better-extended low frequencies. It's not quite as transparent as the
Rotel player, but there isn't a gross difference. Also NAD 5000 is not
quite as sensitive to the cables as Rotel does.

So the conclusion is that it's one of the best entry-level CD players.
But it's still entry-level. Therefore I am selling it and am planning to
get a Melos CD-T Bit player. Therefore you are getting a good deal.

The list price for this player is $499. I am asking $300 for it. I
bought it three months ago, so there is 21 months parts and labor
warranty left. It is (of course) in mint condition, and I have the
original manual and box for it.

Just one last thing. I am leaving for my vacation on the 24th but I'll
be back on the 13th next month (year). So send your reply as soon as
possible so we can arrange something now.

Thanks.

Howdy,
  I've got a 1hr long radio program that I would like to regularly tape. 
  However, I've only got a non-auto-reverse tape deck. This, along with the 
  warning in the manual not to use any 120min tape, means that I can't tape 
  the complete program. But what about all those 110min tapes? I notice that
  TDK puts out a lot of 110min tapes (available at least in MA and MA-X).
  How do these tapes compare to 120min? Are the 110min still too thin for
  reliable use? I would like to get some feedback before trying them.
