Default Anyone tried those cheap usb sound cards?

On dealextreme there are a few starting at $ 2.26 up to $ 10.79
and I wonder how they sound when the output is taken before the earplug
amp which I guess is also in there. I ordered three different ones just to play
with Maybe a clean 5 volts and some decent caps clean them up and make
them into real cheap dac's.

I think the cheaper one is based on a C-media CM108 chip which is quiet interesting:
SPDIF & I2S output
external 12MHz clock

Might be good with external 5V supply & I2S to external DAC & good clock

Datasheet here:

Let us know how it sounds & if you do open one up?
