 I've owned a pair of SR-80s for 3 or 4 years now and they are excellent

 phones, but not 3x better and they cost 3x as much. 

Although it's worth noting that the HD-580s are available (at Amazon at
least) for $125, and they're 90% of the HD-650s.  This is an absolutely
stunning bargain, really.

That said, I wouldn't recommend those to the original poster, because
they're going to need an amp to be driven by most portable players (an
iRiver player made them sound okay; an iPod couldn't get them to
satisfactory volume at max settings; both would have benefited
enormously from an amp), and they leak sound like crazy.

But incredible comfort and sound quality matching that of $3K speakers
for $125 is still an attractive proposition.

 Hi. I'm curious, do any of you know of any portable (pocket) stereo

Your best bet would be to take the player out of the equation entirely.
The iRiver H140 (which has been discontinued for a while) has a digital
output on it, from which you can go to an external DAC.  Put that
together with HeadRoom's Micro DAC/Amp combo, and you'll have a source
that's a worthy match for any headphone.

 The trick is to make all the voodoo, selects, outer joins, etc.

A centralized database is a fine implementation choice for a particular
player, enabling various sorts, filters, and views of the data.  Which
is why almost all programs, from iTunes to WMP to Slim to Foobar, use a
database internally.

But a database is a TERRIBLE place to use as the primary storage for a
file's metadata.  It's difficult to use with multiple applications,
it's a single point of failure that can wipe out all metadata, and it
means that files copied off somewhere else lose all their metadata.

Metadata belongs in tags, and players that use metadata should build
internal database caches of the metadata.  Which is, fortunately
enough, exactly the current situation.

SlimServer is a single application.  Anything you put into SlimServer's

your music, or all the other devices to which you sync it.  That's fine
for metadata you don't really care about in a primary fashion, I suppose
-- if it's only useful to SlimServer, it's just as well that only
SlimServer know about it -- but definitely not how you'd want to handle
Artist/Title/Genre stuff.

 
 You are correct that moving files makes it harder to track the 
 descriptive data, but it is by no means all that hard.

I don't believe you understood what I was saying.  Any time you copy
files in a way that's not aware of the database -- by using a regular
file copy in Windows Explorer, an FTP upload, a BitTorrent thing,
whatever -- the metadata doesn't go along for the ride, and is lost. 
This is one of the well-known problems with centralized metadata
stores, and one of the reason that in-file metadata is standard for
essentially all types of files these days.

Amazon actually has more CD covers than you think.  The key is to

(And someone earlier in the thread asked how cover art was embedded. 
In most metadata schemes, it's possible to put the cover art directly

I wouldn't by IEMs for a main headphone.  They're more comfortable than

significant lengths of time in a daily basis.  If you're going to be in
noisy environments that you want to tune out (airplanes, say), they're
indispensable; but for regular life, they're not entirely comfortable. 


Plus, while the sound quality is amazing compared to earbuds, it's not
as good as an excellent circumaural headphone.  Nor is it as consistent
-- minor positioning differences during insertion (or as they shift
around as you move) can radically change the sound.

I'd recommend the HD-580.  They're phenomenal headphones, with sound
quality rivaling that of $3,000 speakers, and they're only $150.  These
are genuinely one of the best audio buys around.

 Anyone compared the two?  I'm considering selling the Squeezebox for a
 360 due to the additional utility but I'm not looking to sacrifice a
 lot of sound quality (Although I would be willing to sacrifice a
 little)

Possible reasons to stick with the SB:

1.  The Xbox 360 (I've read but not tested) resamples everything to
48KHz.  

2.  The fan in the 360 is loud, for audio gear.  It's not running
full-speed when working as a Media Center Extender, but it's still
running loud enough to be irritating for music purposes.

3.  The 360's UI isn't as nice as the Squeezebox's, and not just
because you need the TV on to use the 360.  (I'm talking here about the
Media Center Extender version; the WMC version isn't better.)

The primary advantages to the 360 over the Squeezebox are that: 1) It
can play PFS DRMed tracks, and 2) it can do a LOT more than just play
music.

Get an amp.  The headphone jack on the SB2 isn't bad, but it's not

volumes without much in the way of distortion; but the difference
between the SB2's headphone jack and the output of a HeadRoom Micro Amp
is huge, a genuine Wow moment if you've got the headphones to benefit
from it.

(For calibration of what I mean by huge:  I think cables make zero
impact, I think DACs in modern equipment make very little impact (I
couldn't tell a difference between the SB2 and the SB2 through a
Benchmark DAC-1), I think regular power amplifiers for speakers don't
make much of a difference once you've gotten above a certain base
quality level -- but I think speakers and headphones make a huge and
obvious difference, and that lossless compression sounds noticeably
better than 192kbps.)

 allows you set the gain of each input so I made sure they were as close

 had to do this by ear as I do not have the appropriate electronic
 measurement tools to be able to ensure they were within +-1dB (if any
 one does I would like to see if you get the same results). Once this

One thing that's interesting to do in those kinds of situations is to
do the initial test, then adjust the levels to equalize it (that is,
turn up the one you thought was worse by a titch), then listen some
more.  It's surprising how often the one that you think is better ends
up losing that title if you just titch up the volume on the other one.

I _think_ that I can tell a difference between it straight-up and
running through the HeadRoom Micro DAC, but I wouldn't swear to that; I
didn't do anything like a rigorous comparison, because I knew that I was
keeping the Micro DAC no matter what (it has a USB input, and it's way
way better than the sound card in my computer, so I use it to listen to
music when at the computer) and didn't end up keeping it hooked up to
the SB.  Associated equipment on that was HeadRoom's Micro Amp driving
HD-650 headphones.

It's possible that my speaker system isn't good enough to reveal
differences between the built-in and an external DAC, so if you've got
a system that you've spent $20K on, you'll probably want to try it out
anyway.  But for the most part, I expect that differences between
