After purchasing the Burson Conductor Voyager and transitioning from the CMA18 one-box system to the detachable configuration, I felt the overall musical performance improved in a much more structured and refined way. The upgrade brought greater coherence and clarity across the entire presentation.

I also purchased the Burson Fusion Core directly from the Burson Audio website, and I was genuinely surprised to receive it just two days after placing the order. The delivery speed exceeded my expectations. Once I installed the Fusion Core in the Voyager, the sound quality took another clear step forward, offering an even more noticeable refinement and enhancement compared to before.

The System

Listening with

Sennheiser HD 800 S · Headphones: open-back, dynamic, circumaural

Impedance: 300 Ω
Sensitivity: 102 dB SPL @ 1 V ≈ 96.8 dB/mW (calc.)
Frequency response: 4 Hz – 51 kHz
Plugs / cables supplied: 6.35 mm unbalanced; 4.4 mm balanced

Matching notes: At 300 Ω and 102 dB/V, the HD 800 S is a high-impedance load that needs voltage more than current: about 2.5 V (21 mW, 8.4 mA) for 110 dB SPL (calc.). Burson rates the Conductor Voyager at 1 W (XLR) / 0.5 W (SE) into 300 Ω, which is about 17.3 V / 12.2 V RMS (calc.), roughly 17 dB / 14 dB more than that. The Conductor Voyager’s 0.45 Ω headphone output impedance is 1/667 of the load. ^{[1] [2] [3]}
