7 things, making this device better then PC with a sound card:

1. Not everyone PC's sound card have SPDIF/TOSLINK outputs.
2. Not everyone PC's sound card have I2S output
3. Not everyone PC's sound card have external MCLK input
4. JKG 384-12 is much smaller then desktop PC
5. JKG 384-12 have less surrounding cables, then desktop or laptop with external sound card
6. JKG 384-12 can be powered from the battery, allowing "on field operation"
7. JKG 384-12 can be powered from the battery, avoiding the ground loops
