Nathan’s Burson Soloist 3X GT with Denafrips Venus II and Meze Empyrean

• Impedance: 31.6 Ω
• Sensitivity: 100 dB SPL (1 mW / 1 kHz) ≈ 115.0 dB/V (calc.)
• Frequency response: 4 Hz – 110 kHz
• Plugs / cables supplied: 4-pin mini-XLR cable; 3 m OFC XLR cable
• Other: max SPL >130 dB; THD <0.1%; ~430 g; Rinaro driver

Matching notes: At 31.6 Ω and 100 dB/mW, the Meze Empyrean is a low-impedance load, and an efficient one: about 0.56 V (10 mW, 18 mA) for 110 dB SPL (calc.). Burson does not publish a 31.6 Ω rating for the Soloist 3X GT. Its 16 Ω and 32 Ω ratings (10 W XLR / 5 W SE; 8 W XLR / 4 W SE) fall either side of it. The Soloist 3X GT’s 0.5 Ω headphone output impedance is 1/63 of the load. ^{[1] [2] [3]}

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.
