Device
| Name | Entry-Tier USB-C Dongle DAC (Single CS43131) |

| Power @ 300Ω | 45 mW |
| Output impedance | 1.0 Ω |
Analysis
- Power headroom: ~130 mW available at 16Ω. Sufficient for the transducer's sensitivity.
- Damping factor: 16:1. Above the 8:1 audibility threshold; bass response is well-controlled.
- Direct termination: No direct connector match between transducer (0-78mm-2pin) and device outputs (3-5mm-trs). Use a balanced upgrade cable terminated to one of the device outputs.
Cable recommendation
If the transducer ships with a detachable cable (detachable), a balanced upgrade cable terminated to one of the device's outputs (3-5mm-trs) gives you the most power and the cleanest signal path. See our balanced cable buyer guide.
