This is just too cool.  Where did you hear this?  Are you sure this is
a feature of the MD?  I've read a lot of articles about the MD and I've
never seen this discussed.  If this is true, then then DCC just got
another nail in it's coffin.

This should also mean that players (at least some day) could easily
delete/renumber/re-order tracks with little problem.

My DAT machine will let me re-record tracks, insert new tracks, add
skip marks, and even renumber all the tracks (because after inserting
they get out of sequence).  But you are still limited to the amount
of space available on the tape when you record over an old track.

Imagine being able to record a collection of your favorite songs, and
then be able to delete and add new songs over time without having
to re-record the whole disk?

DCC has the ability to encode text in the data so it displays when you
play the songs.  Until recently, I didn't think MD had this feature -
which would be a big shame.  I always felt this was something that
should have been part of the CD standard.  But I saw a picture of an MD
player the other day and it included an LCD display that was showing
the name of the song/album - so it looks like MD has this feature
also.

One day, we will have an affordable juke box type systems to store all
our music.  You just put the disks in, and it reads all the info off
the disks.  You get a nice menu that lists all the music and it can
even cross reference the data and show it to you sorted by title, or
musician, etc.

I have seen this mentioned before.  Just how can a well designed
double blind experiment using a two alternative forced choice
procedure "reduce" your sensitivity?  After all the data returned
will simply be a probability of making a corect identification.
On 100 trials, that should give a fairly accurate indication of your
subjects sensitivity to change in the componedts manipulated.

Add to this a set of trials where you ask the subject to make 
subjective comments like "better, worse, same" to the manipulations
and then we can not only start to see if there is any detectable
difference but if the change is "better" and on what proportion of
trials it was judged better.

I have the same problem. It gets even worse when I connect the VCR.
This happens:

TV audio outs connected to preamp: no hum
Connect antenna (cable) to TV: a bit of hum.

Disconnect everything.

VCR audio outs to preamp: Lots of hum
Connect antenna to VCR: a bit of hum

Funny, must be something electrical :-)

The high-end hi-fi store suggested a ground-breaker (they were out at the moment).
The said it was a common problem.

Anybody knows what a ground breaker is?? And will it help??

	I would suggest that you stay with an all-wood or other

use those fat rubber washers to isolate the gear from the frame.

Hello,

I wonder wonder how come people complained about the "curved lines"
on the actual Nak line: have they looked at the Harman-Kardons???
Naks are _not_ curved compared to them.

What I hope they bring out is single CD versions of the CD1,2,3 players.
To me, a CD changer is *not* a good base for """real""" hi-fi (too many
moving parts succeptible (sp?) to vibrations, etc.). And what about 
optical links to an external DAC???

And a simpler CD1 (CD1.5 ???) could be cheaper, because no "MusicBank"
system"... It would make way more apealing to the budget-conscious 
audiophile (I still can't get over Stereophile calling a $1400US amp
a "budget" model...  =8-O !!! )

If they brought out a single CD version of the CD1, I'd trade my CD4 
faster than you can say "Nak"...

Which leads me to ask:

I've seen people advocate Zoebel-ing the individual drivers in a
multiamped installation.  Can any single driver actually pose a wierd
enough load to a reasonable power amplifier to make this exercise
worth the effort?

Reference was made earlier to using a Zoebel to smooth out the
impedance bump of a woofer at resonance.  Aperiodic (resistively
vented ? Lossy sealed ??) enclosures are said to do the same thing.
Do both techniques have the same effect on the complete system's
acoustic response, or does the Zoebel approach somehow only change
what the amplifier sees?

In my main video system, I have a couple of VMPS ST-IIa/R speakers for the
front speakers; the literature that came with them claims an efficiency of
101 dB (1W/1M) (none of the drivers are horn-loaded) and a -3dB point at only 
17 Hz.  Now, just for fun, I A/Bed them with a pair of B&W speakers that
claimed an efficiency of 90 dB--and if there is a difference in the volume
produced by these two pairs of speakers with 11 dB different claimed
efficiencies, it was small enough to be hard to tell.  Further, the 
Morel tweeters used in the VMPS speakers are only rated at 90 dB
efficiency themselves, which suggests to me that it would be difficult 
to design a speaker with 101 dB efficiency around them.

So, how fast and loose do manufacturers play with specs like this?  Are
there tests out there that actually give the results given?
