Post Info

Sounds great and feels very premium with plenty of power for future upgrades.

The System

Listening with

Focal Alpha 65
Focal Clear MG · Headphones: open-back, dynamic (40 mm Mg M-dome), circumaural
  • 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: 3.5 mm cable (1.2 m) with 6.35 mm adapter; 4-pin XLR cable (3 m); cup sockets 3.5 mm

Matching notes: At 55 Ω and 104 dB/mW, the Focal Clear MG 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 3 Reference. Its 32 Ω and 100 Ω ratings (5 W SE; 1.75 W SE) fall either side of it. The Conductor 3 Reference’s 0.5 Ω headphone output impedance is 1/110 of the load. [1] [2] [3] [4] [5]

Specs from manufacturer data unless a source below says otherwise. “calc.” values are worked out from those figures (V = √(P × R); 110 dB SPL used as a loud reference level). Gear listed without specs is not in our spec library yet.
