Pairing analysis: power headroom, damping factor, output topology and signal path. Good match
Transducer
| Name | Multi-BA Studio Reference IEM (6-Driver 3-Way Crossover) |
|---|---|
| Type | Iem |
| Driver | balanced-armature · n/amm |
| Impedance | 22 Ω |
| Sensitivity | 112 dB/mW |
| Recommended drive | 5 mW |
Device
| Name | Entry-Tier USB-C Dongle DAC (Single CS43131) |
|---|---|
| Category | Portable Dac |
| Topology | Class AB integrated |
| Power @ 32Ω | 130 mW |
| Power @ 300Ω | 45 mW |
| Output impedance | 1.0 Ω |
Analysis
- Power headroom: ~130 mW available at 22Ω. Sufficient for the transducer's sensitivity.
- Damping factor: 22:1. Above the 8:1 audibility threshold; bass response is well-controlled.
- Direct termination: No direct connector match between transducer (mmcx) 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.
