7 things, making this device better then PC with a sound card:- Not everyone PC's sound card have SPDIF/TOSLINK outputs.
- Not everyone PC's sound card have I2S output
- Not everyone PC's sound card have external MCLK input
- JKG 384-12 is much smaller then desktop PC
- JKG 384-12 have less surrounding cables, then desktop or laptop with external sound card
- JKG 384-12 can be powered from the battery, allowing "on field operation"
- JKG 384-12 can be powered from the battery, avoiding the ground loops
Can be purchased as a complete device,
