why does "Shuffle" sound best?

I was thinking the same thing...

First of all kevmakara - WRONG. Having flash memory does not give better music. The Shuffle's better sound quality (by some opinions this is not really true, but then again not all people think the same... or hear the same for that matter) comes from the output stage. If you are not a techie you wil probably not understand but here goes:
Ipods generally have very good sound quality... there is little distortion (in fact almost none) and overall they simply rule. BUT... full sized ipods have for a very long time now been manufactured with an output stage (the part of the amplifier that drives the headphones) based on a transistor - capacitor design. This being said there is a very unfortunate consequence of using a capacitor - if it doesn't have enough juice to feed the headphones, high energy sounds... like bass, actually drive the capacitor way down in charge and it no longer has enough juice to deliver the punch.
That being said, the Shuffle uses a capacitor-less design. It has 2 transistors that drive the headphones independently (one for the plus part of the wave, and the other for the minus part). This construction is called "push-pull". And if you understood this, then there you are. The shuffle doesn't necesarilly sound better. It just has a better punch to the music :)

and here we go again with the "factory equalizer setting" drivel some of you guys just won't quit. The shuffle has no equalizer. It has been demonstrated. EQ's create artifacts in the sound. Superior harmonics that show up in the high frequencies. This is just bad for the sound. So just stop it. No eq's people! and get over it. The shuffle has a very good spectral image therefore it has no EQ

ok... let's begin
First of all: wyneken... i'm enough of a man to see when i do something wrong and to admit it. Therefore I admit that the "drivel" bit was totally rude and I am sorry.
Second of all: I am actually flatered that you consider me to be a hardcore techie... even though I am just studying to become one (I'm a student at the Electronics College in Bucharest :P )
And Third of all: I got a little bit carried away when I saw how this issue about how "the shuffle was <worked> to sound better, though it is really a lot worse than the full sizes" issue arises everytime someone asks about it's sound quality. I guess I just really like my Shuffle (and maybe I am a little neurotic about getting people to accept what is objectively true :D )

I keep hearing that the Shuffle sounds the best--in fact Apple said the new iPod 5G sounds as as good if not better than the Shuffle--which seems to suggest that the Shuffle has set the bar for all in the iPod family. Is this the consensus, and why?

2nd best.

I have the 5G iPod and did a comparative listen on the same tracks. The 5G sounds better.

haha, and that is the answer. definatively.

on a serious note, what headphones where you using? i'll assume the test was double blind? and what was your sample size? did you sample tracks from multiple genres? what file format did you use? how long did you listen for? what are some specific qualities you prefered in the 5g over the shuffle?

No, the effect of shorter signal path has no effect. A home stereo has signal paths about 200 times longer and still sounds great (if it is a good quality one of course).

Signal path length only matters when the wavelength of the signal starts getting comparable to the path length. This is well up into the GHz range, and audible frequencies top out at 20kHz, which is about a million times lower frequency.

As someone else said above, the reason the Shuffle sounds better is its push-pull amplifier, as opposed to the capacitor-based design in earlier iPods. It's not a subjective thing, guys; the Shuffle produces a better output waveform, period. See for yourself: have a look at the graphs on the page that stryder linked to above:

Actually 3rd best.

1) 5G
2) Nano
3) Shuffle
