Hybrid Tribrid IEM with Reference Portable DAP
Pairing analysis: power headroom, damping factor, output topology and signal path. Good match
Transducer
| Name | Hybrid Tribrid IEM |
|---|---|
| Type | Iem |
| Driver | hybrid · 9 (DD)mm |
| Impedance | 18 Ω |
| Sensitivity | 106 dB/mW |
| Recommended drive | 20 mW |
Device
| Name | Reference Portable DAP |
|---|---|
| Category | Dap |
| Topology | Class A balanced (BTL) |
| Power @ 32Ω | 650 mW |
| Power @ 300Ω | 210 mW |
| Output impedance | 0.8 Ω |
Analysis
- Power headroom: ~650 mW available at 18Ω. Sufficient for the transducer's sensitivity.
- Damping factor: 22.5:1. Above the 8:1 audibility threshold; bass response is well-controlled.
- Direct termination: No direct connector match between transducer (pentaconn-ear) and device outputs (4-4mm-balanced, 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 (4-4mm-balanced, 3-5mm-trs) gives you the most power and the cleanest signal path. See our balanced cable buyer guide.
