Pairing analysis: power headroom, damping factor, output topology and signal path. Good match
Transducer
| Name | Planar Magnetic In-Ear Monitor (14.2 mm Driver) |
|---|---|
| Type | Iem |
| Driver | planar-magnetic · 14.2mm |
| Impedance | 32 Ω |
| Sensitivity | 98 dB/mW |
| Recommended drive | 80 mW |
Device
| Name | USB-C Dongle DAC with Dual CS43131 and Balanced Out |
|---|---|
| Category | Portable Dac |
| Topology | Class AB integrated (CS43131 internal) |
| Power @ 32Ω | 210 mW |
| Power @ 300Ω | 62 mW |
| Output impedance | 1.0 Ω |
Analysis
- Power headroom: ~210 mW available at 32Ω. Sufficient for the transducer's sensitivity.
- Damping factor: 32:1. 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, 4-4mm-balanced). 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, 4-4mm-balanced) gives you the most power and the cleanest signal path. See our balanced cable buyer guide.
