Desktop Grounding Tips
- Connect DAC and active speakers to the same power strip to avoid ground loops
- Use XLR balanced cables over RCA — superior noise rejection in RF-noisy desktop environments
- Keep Bluetooth antenna away from Wi-Fi router and USB 3.0 ports (2.4GHz interference)
- LDAC Bluetooth is sufficient for casual listening; switch to USB wired for critical sessions
