Although it’s my first experience with Burson Audio, I’m in love with its quality and sound. It’s sad that since I have to go business trip quite often, I cannot enjoy it daily. But I’m definitely going to purchase the V7 classic op amps as well and share my experience with people around me.

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 Soloist Voyager at 0.64 W (XLR) / 0.32 W (SE) into 300 Ω, which is about 13.9 V / 9.8 V RMS (calc.), roughly 15 dB / 12 dB more than that. The Soloist Voyager’s 0.5 Ω headphone output impedance is 1/600 of the load. ^{[1] [2] [3]}
