Aldo’s Burson Conductor 3 Reference with Gauder Akustik DARC 80 and Audeze LCD-3

• Impedance: 110 Ω
• Sensitivity: 101 dB/1mW (at Drum Reference Point) ≈ 110.6 dB/V (calc.)
• Frequency response: 10 Hz – 50 kHz
• Plugs / cables supplied: 4-pin XLR cable; 4-pin XLR to 6.35 mm adapter cable; 6.35 to 3.5 mm adapter
• Other: recommended power >250 mW;

Matching notes: At 110 Ω and 101 dB/mW, the LCD-3 is a low-impedance load, and an efficient one: about 0.93 V (7.9 mW, 8.5 mA) for 110 dB SPL (calc.). Burson does not publish a 110 Ω rating for the Conductor 3 Reference. Its 100 Ω and 150 Ω ratings (1.75 W SE; 1.16 W SE) fall either side of it. The Conductor 3 Reference’s 0.5 Ω headphone output impedance is 1/220 of the load. ^{[1] [2] [3] [4]}
