Hi! Been looking through the virtual ground concepts for creating a virtual pos/neg supply to opamps for headphones amplifiers that has been posted here and at Tangentsoft's homepage. But, if the input voltage is known and stable, why not simply put a voltage regulator that regulates at half that voltage? 5V supply here because of designing for USB voltage, but the concept can be used at any voltage levels, with an adjustable regulator. Any reason this wouldn't work?

EDIT! It has come to my understanding that the virtual ground is of course serving AC signals, and therefore need to both source and SINK current. Therefore the above design is moot.
Please disregard this suggestion, and put it in the trash can. I would have deleted the thread if possible...
