Clinton’s Burson Conductor 3X Reference with Dynaudio BM6A and Focal Clear HP

Published on

Post Info

I recently purchased my first high end headphones for both enjoyment listening and for the ability to check my recording mixes on highly resolving but non “pro-audio” equipment. I was not satisfied with the tonal balance of my Focal Clears from my audio interface, so after much research decided on the Burson Conductor. I am thrilled with the sound so far- much more balanced presentation with superior imaging to my Apogee interface, and for enjoyment listening I also really like the Burson on my studio monitors! So far I’m convinced the outstanding reviews of Burson are well-deserved, and I look forward to getting to know the system even better!

The System

Listening with

Dynaudio BM6A
Focal Clear · Headphones: open-back, dynamic (40 mm Al/Mg M-dome), circumaural · discontinued
  • Impedance: 55 Ω
  • Sensitivity: 104 dB SPL / 1 mW @ 1 kHz ≈ 116.6 dB/V (calc.)
  • Frequency response: 5 Hz – 28 kHz
  • Plugs / cables supplied: 4-pin XLR; 6.35 mm; 3.5 mm cables supplied

Matching notes: At 55 Ω and 104 dB/mW, the Focal Clear is a low-impedance load, and an efficient one: about 0.47 V (4 mW, 8.5 mA) for 110 dB SPL (calc.). Burson does not publish a 55 Ω rating for the Conductor 3X Reference. Its 32 Ω and 100 Ω ratings (5 W XLR / 2.5 W SE; 1.75 W XLR / 0.88 W SE) fall either side of it. The Conductor 3X Reference’s 0.5 Ω headphone output impedance is 1/110 of the load. [1] [2] [3] [4] [5] [6]
