Well, ze crafty testers use their own equipement to test stuff. So hard facts can be biased only so much by marketing.
Cool thing is these facts really bring out the fanboyism in the thread...

Heres the disortion facts:
Ipod Shuffle 2. Gen very low power single-ended, capacitor-coupled output.
THD+N (%)
0,140(Best 0,006)
Frequenz 20 Hz (dB) 0,21(Best 0,01)
Frequenz 20 kHz (dB) 0,57(Best 0,03)
Ipod Shuffle 1. Gen push-pull output
THD+N (%)
0,0085(Best 0,006)
Frequenz 20 Hz (dB) 0,08(Best 0,08)
Frequenz 20kHz (dB) -2,23(Best 0,04)
ALSO: Testing chain: External loopback (line-out - line-in)
Sampling mode: 16-bit, 44 kHz headphones into motu 828:
Frequency response (from 40 Hz to 15 kHz), dB: +0.04, -0.22Very good
Noise level, dB (A): -104.7Excellent
Dynamic range, dB (A): 88.1Good
THD, %: 0.0097Very good
IMD + Noise, %: 0.014Very good
Stereo crosstalk, dB: -105.5Excellent
IMD at 10 kHz, %: 0.016Very good
THEN:
40-Hz square wave:
Pretty much stays that way under load:
Zen micro + others look more like this under load: (edit: Zen Micro delivers a clean wave without load.)
Summary: 1. Gen is a clean driving powerfull little thing. Sounds great too.
[size=large]2. Gen sucks. Really bad.[/size]
That is all.
