What is the best "Op-amp Circuit" that....

  • Has stereo output & uses 8ohm speakers?

  • Has a 3.5mm audio jack input?

  • Can receive it's audio signal from...

    -A- a MP3 player's 3.5mm earphone jack
    -B- a laptops 3.5mm speaker jack
    -C- a PC microphone (external mic)

Things like the supply voltage avaiable, and the method of volume control (digitally controlled? or analogue with a pot?) and the wattage of the speakers will help us to decide on your dream chip....
