Analysis
- Power headroom: ~1642 mW available at 80Ω. Sufficient for the transducer's sensitivity.
- Damping factor: 160:1. Above the 8:1 audibility threshold; bass response is well-controlled.
- Direct termination: No direct connector match between transducer (3-5mm-trs) and device outputs (4-4mm-balanced, 6-35mm-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, 6-35mm-trs) gives you the most power and the cleanest signal path. See our balanced cable buyer guide.
