Absolutely fantastic! I am genuinely impressed with the quality and performance. It truly stands out, and I couldn’t be happier with my experience. This has definitely exceeded my expectations!

The System

Listening with

Genelec G3 · Speakers: active two-way bookshelf, Class D 50 W bass + 50 W treble

Frequency response: 47 Hz – 25 kHz (-6 dB); ±2.5 dB from 54 Hz
Connectors: not published
Other: 130 mm bass + 19 mm tweeter

^[1]

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 GT4 at 1.3 W (XLR) / 0.65 W (SE) into 300 Ω, which is about 19.7 V / 14.0 V RMS (calc.), roughly 18 dB / 15 dB more than that. The Soloist GT4’s 0.5 Ω headphone output impedance is 1/600 of the load. ^{[2] [3] [4]}

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 Soloist GT4. Its 32 Ω and 100 Ω ratings (10 W XLR / 5 W SE; 8 W XLR / 4 W SE) fall either side of it. The Soloist GT4’s 0.5 Ω headphone output impedance is 1/110 of the load. ^{[5] [6] [3] [4]}
