The PC audio market has been churning out some great new high fidelity soundcards lately. A good example here is the recent release of the new Essence STX headphone card, which stirred up the audio community and caught the attention of people who usually look for external headphone amplifiers. Some of you may know there were rumors of ASUS expanding the Essence Line-up with possibly a PCI model.

Guru3D has the prototype the engineering sample of the Essence ST in our audio lab today, and will bring you a sneak preview on it to show you what ASUS is working on inside that chocolate factory of theirs.
