John’s Burson Conductor 3X GT with Audeze LCD-5

• Impedance: 14 Ω
• Sensitivity: 90 dB/1mW (at Drum Reference Point) ≈ 108.5 dB/V (calc.)
• Frequency response: 5 Hz – 50 kHz
• Plugs / cables supplied: 2.5 m braided 4-pin XLR balanced cable; 4-pin XLR to 6.35 mm adapter; 6.35 to 3.5 mm adapter
• Other: recommended power >500 mW (min >100 mW; max 5 W RMS);

Matching notes: At 14 Ω and 90 dB/mW, the LCD-5 is a low-impedance load, and a fairly demanding one: about 1.2 V (100 mW, 85 mA) for 110 dB SPL (calc.). Burson does not publish a 14 Ω rating for the Conductor 3X GT; its nearest published rating is 10 W XLR / 5 W SE into 16 Ω. The Conductor 3X GT’s 0.5 Ω headphone output impedance is 1/28 of the load. ^{[1] [2] [3] [4]}
