Hey Chris,

I really appreciate you�re taking a few minutes to address this.  I�m still
struggling with Yahoo mail settings here, so bear with me.  I�ve got the
text width right, but I didn�t used to be able to delete mail I was
reading, and have the next email listed forward chronologically pop up. 
Yahoo would go backwards.  So I end up reading replies before the original
posts.  Yahoo has just reinvented their interface, so I�ll go check
settings to see if I can change that.

That was my experience on my first tests with this Libretto and these Altec
Lansing speakers.  The audio quality the speakers is reasonable for a
computer system, but not really high end consumer class audio.  The
Libretto has a very crude sound chip in the Yamaha OPL3-Sax.

That was my take on it.  I�m guessing that the increase in the introduction
of noticeable artifacts is going to increase perhaps exponentially (haven�t
looked at the math) with a linear increase of number of times the signal is
re-encoded.

You�ve hit on two of my biggest problems at the moment, the poor OPL3-Sax
sound chip, and a broken set of already pretty poor headphones.  I�m
spending a bit of time now with family at one end of the country, while
most of my computer and stereo equipment is at the other end.

I have a bunch of duplicate MP3s on the Libretto encoded at both 128K and
192K taking up space.  They both sound identical through this equipment.  I
thought maybe I�d just go ahead and re-encode the 192K files with Lane VBR,
and shrink them down to about the size of the 128K files, and then axe the
128K files.  But I guess I better keep them until I can really A-B them on
a Rio, or something with sufficient quality.  I was just hoping to get
feedback from someone who's been through this.

Ah cats!  They can be amusing can�t they?  At least when their mischief
isn�t presenting a financial calamity. ;-P  

Thanks for the tip on the earbuds.  One reason I�m looking at the Rio is
the fact that they have one of the best signal to noise specs of the
portables out there I've looked at.  Something that still bothers me about
them is the proprietary rechargeable battery they come with.  You have to
buy their expensive battery if you need to replace it.  I�d prefer to buy
something that uses the NiMH AAs I use for other equipment.  I did read a
post on the net somewhere where a guy said he disregarded the
manufacturer's warning, and went ahead and managed to install common NiMH
AAs.  He said they seemed to be working fine, at least at the point he
wrote the article.  This is what�s been holding up my decision to get a
Rio.

The practical choice as someone pointed out, would be a MP3 CD player.  At
some point I�ll get one no doubt.  But my listening on the run at this
point is relatively limited, and the shirt size and light weight of the MP3
portables is pretty attractive to me.

By DSP settings, are you referring to its audio equalizer that offers,
"..user defined bass/treble.."?  That�s another thing I like a lot about
the Rio.

Heh...  I went through a period edging on high-end snobbery for a while,
never really getting too wrapped up in it all (or really that knowledgeable
about it).  I was sharing a home with a friend who was really
"over-the-top", but the most level-headed and practical of the audiophiles
in his crowd.  So I got quite an education.  Not having the kind of income
to pursue that level of equipment, I developed a 'when in Rome'
adaptability to whatever kind of system was around at the moment.  If a
person can be more infatuated and thrilled a greater percentage of the time
with music coming through a $19.95 Walkman than an audiophile with his
$40,000 setup, he�s ahead in the game as far as I can see!  Of course I�m
always in awe of the sound coming from most high-end systems.  But a good
deal of the audiophiles I�ve known seemed to derive more pleasure with
hours and hours tweaking their systems, as opposed to spending the same
amount of time actually listening to their recordings!

This is just the sort of feedback I appreciate Chris.  Maybe a few more
listers have their own takes on how much, of any noticeable distortion
thry�ve noticed when attempting to shrink a few irreplaceable 192K+ MP3s.

Ciao for now,

Shel
