   True, it is quite rare to find two decks with the same alignment to
play and record in Dolby C.  Dolby C is very sensitive to alignment of
the heap on the tape.  I own a Denon DRM-800 and I just bought a
DR3-610.  The very first thing I did when I got the deck home was to
set the tape head alignment on the DRS-610 to as close as I could to
the DRM-800.  This worked quite well, but tapes recorded on the Denon
drm-800 in dolby C still sound better played back on the same deck.
The same is true for the DRS-610.  Just my 2 cents worth!

I've had Maggies with ribbon tweeters for some years now, and have not yet had
any ribbon trouble. I know two other people in this town who also have MG3
or MG3a who have not had any problems either. So the problem is not too
serious. If/when they do eventually fail, they can be replaced fairly
cheaply. 

I must admit to having the same worries before I bought.

     You are now likely in the main output lobes of your tweeters.
     And pulling speakers away from walls can help with midbass
     excess.  (or putting bass-shy speakers in corners does the
     opposite....)

     A foot or two of speaker repositioning will almost always
     exceed the effects of exotic cables and most other typical
     tweaks.  And UNLIKE most tweaks, it is well based on sound
     engineering principles.

     Now try tipping them (or stands) so the tweeters are more or
     less aimed at your ears in listening position.  Then angle them
     in a bit...and keep them AT LEAST 3-4 feet or more from side
     walls.  

     Some speakers also sound better when at least 3-4 feet from the
     walls behind them...as long as it doesn't make them TOO close
     to you (or the wall behind you....)

     Try removing the grilles...some sound better w/o, some with.

A couple of questions.  Do you really need a changer.  I know that
there are several out there, but given the length of CD's, and the ease
of use, an in-dash CD unit might not be a bad idea.

I have an in-dash unit, and it will have been in place for 5 years next
month.   The only skips are on some really bad portions of the local
toll-road.  I also have stiff suspension and semi-racing radials.  You
can almost tell heads or tails when you run over a dime?   I feel
certain that you would almost never get a skip on a normally suspended
car.

That cost me $500 five years ago - and has never failed.  Units are now
in the $200+ range when on sale.  Changin a single disk is as easy or
easier than a cassette.

I see, dyslexics cannot make quality posts.  Excuuussseee me, I guess I 
can't make ayn quality posts.  I flunked spelling and handwriting
from 4th grade until they stopped grading it, but I manage well enough
to do world-class research in audio signal compression, and editors are
more than willing to fix my spelling. Furthermore, despite the fact they
know I can't spell, they surely send me enough papers to review.

Let me offer you another bit of advice:

4) Don't take someone out of context for the sole purpose of diminishing
them or their opinions.

5) Don't start trying to put form over content.  Only MBA's and Yuppies
can get away with that, and as the world is already showing, they

I have a slightly different question along the same lines:  Can I put together
a system from individual components that sounds better than a mini system, and
for not much more money?

I listened to a Panasonic mini system (SC-CH55) and it sounded suprisingly
good for $500.   I wonder though, if I could do better spending :

   Speakers $200
   Reciever $200
       CD   $120
      Tape  $130
   --------------
            $650

And get a better sounding system for slightly more money. 

Questions:

1.  Are my price ratios out of whack to maximize sound quality / dollar ?
2.  Which speakers & recievers are "best" in this price range?
3.  Has anyone put together a low-end component system that they are 
    particularly pleased with ??

When I was getting the Minimus 7's to hook up to my TV, I
compared them to the Minimus 77's.  Both were connected to some
RS reciever tuned to a top 40 station an the equilizer was set to
flat.  Tha main difference was in the bass response.  The 7
basically has none, while the 77 has a boomy upper bass and no
low bass.  Since 'The Simpsons' doens't have any 16 Hz organ
notes, I went with the 7's and Homer doesn't sound like he's
talking into a barrel.  In summary, I find the 7's to sound
better and they're less expensive.

Yes, the ideas are certainly impressive.  I've never heard it in anger, so I
can't comment on whether (IMHO) it works or not.

As for the Keltic, that'll be solidly in the Analogue domain, I can be almost
certain.  I've also heard from several people who've listened to the Keltic
system and not one of them has liked it.  There may or may not be a moral in

I believe that you have to connect each component to a Kenwood Receiver.  The
manual that came with my Kenwood 8010 reciever says that all of the individual
components are connected to the receiver.  It has four jacks on the back for
remote link.  I think that the reciever is the only device that can send a
command over the remote link, all of the other devices just listen.  For high
speed recording to work both your CD player and tape deck must have the high
speed capability, only some tape decks have the high speed option.

The only person who responded mentioned that you should be able to tell where
the instruments are in relation to you (the listener).  Well, isn't this highly
dependent on the source recording?  I didn't think that speakers could create
something out of nothing like that.  Could someone suggest a CD or tape to buy
which would enable us to test to see if our systems have good imaging?  Maybe
a walk-through?

I'm looking to purchase a new high-end walkman $150-$200 and was wondering
if anyone had any suggestions.  First of all I seems that every walkman that
I have bought quickly dies within the year (not abused).  I have decided to go  
for quality instead of economy with this purchase.  Question: Aiwa v. Sony? , 
How good is the DSP on some of the newer Aiwa's?  Durability? blah blah blah...
