Totally,
Martin suggested something using what Ray already had (arduino - L298), but these chips seems perfect.
and can easily be control thanks to a line out and small electronic circuit (OP AMP)
You meant: (square wave) --> [dac] --> line out --> op amp --> Step (logic)
Right?

hello,
electronic circuit like : http://reprap.org/wiki/Pololu_stepper_driver_board [http://reprap.org/mediawiki/images/a/a3/0J4575.1200.jpg]http://reprap.org/wiki/Pololu_stepper_driver_board
Pololu stepper driver board - RepRap - RepRapWikihttp://reprap.org/wiki/Pololu_stepper_driver_board reprap.org Please note: Pololu stepper driver boards has 0.05 ohm sense resistors instead of StepStick 0.2 ohm. A Pololu stepper driver board is a well known RepRap machine ...
or http://www.schmalzhaus.com/EasyDriver/ can control the steeper in a more acurate way than what you can do with an audio amplifier. (see datasheet for more info about the way this chip control a motor).
they are inexpensive and can easily be control thanks to a line out and small electronic circuit (OP AMP)
I think you will have better result using this dedicated chip than hacking an audio amplifier.
