The System

Listening with

ADAM Audio A7X · Speakers: active nearfield studio monitor (7 in woofer, X-ART tweeter) · discontinued

Frequency response: 42 Hz – 50 kHz (-10 dB)
Inputs: XLR / RCA
Input impedance: 30 kΩ
Other: built-in amps 100 W RMS woofer (PWM) and 50 W RMS tweeter (A/B); max SPL >=106 dB (sine, 100 Hz-3 kHz at 1 m); pair >=114 dB; crossover 2.5 kHz; input impedance 30 kOhm; THD <=0.5% (90 dB / 1 m, >100 Hz)

Audeze LCD-4z · Headphones: open-back, planar magnetic, circumaural

Impedance: 15 Ω
Sensitivity: 98 dB/1mW (at Drum Reference Point) ≈ 116.2 dB/V (calc.)
Frequency response: 5 Hz – 50 kHz
Plugs / cables supplied: 2.5 m braided 4-pin XLR balanced cable; 4-pin XLR to 6.35 mm adapter; 6.35 to 3.5 mm adapter
Other: recommended power >250 mW (min >100 mW);

Matching notes: At 15 Ω and 98 dB/mW, the LCD-4z is a low-impedance load: about 0.49 V (16 mW, 33 mA) for 110 dB SPL (calc.). Burson does not publish a 15 Ω rating for the Soloist Voyager; its nearest published rating is 10 W XLR / 5 W SE into 16 Ω. The Soloist Voyager’s 0.5 Ω headphone output impedance is 1/30 of the load. ^{[2] [3] [4]}

ZMF Verite Open · Headphones: open-back, dynamic (vapor-deposited beryllium), circumaural

Impedance: 300 Ω
Sensitivity: ~97 dB/mW (approx., “~” as published)
Frequency response: not published
Plugs / cables supplied: not published (ZMF lists no connector type)

Fostex TH909 · Headphones: open-back, dynamic (50 mm Biodyna, 1.5 T neodymium), circumaural · discontinued

Impedance: 25 Ω
Sensitivity: 100 dB/mW ≈ 116.0 dB/V (calc.)
Frequency response: 5 Hz – 45 kHz
Plugs / cables supplied: detachable 3 m 7N-OFC Y cable, 2-pin rhodium-plated sockets; 6.3 mm plug (XLR cable ET-H3.0N7BL optional)
Other: max input 1,800 mW; approx. 390 g without cable

Matching notes: At 25 Ω and 100 dB/mW, the TH909 is a low-impedance load, and an efficient one: about 0.5 V (10 mW, 20 mA) for 110 dB SPL (calc.). Burson does not publish a 25 Ω rating for the Soloist Voyager. 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 Voyager’s 0.5 Ω headphone output impedance is 1/50 of the load. ^{[7] [3] [4]}

Dan Clark Audio EXPANSE · Headphones: open-back, planar magnetic, circumaural

Impedance: 26 Ω
Sensitivity: ~90 dB/mW
Frequency response: not published (page states “Yes, it has one”)
Plugs / cables supplied: VIVO cable
Other: 418 g; THD <0.1% ref 80 dB

Abyss Diana DZ · Headphones: open-back, planar magnetic, circumaural

Impedance: 50 Ω
Sensitivity: 92 dB/mW ≈ 105.0 dB/V (calc.)
Frequency response: 5 Hz – 65 kHz
Plugs / cables supplied: JPS Labs cable with choice of 3.5 mm, 6.3 mm, 4-pin XLR or 4.4 mm plug

Matching notes: At 50 Ω and 92 dB/mW, the Abyss Diana DZ is a low-impedance load, and a fairly demanding one: about 1.8 V (63 mW, 36 mA) for 110 dB SPL (calc.). Burson does not publish a 50 Ω rating for the Soloist Voyager. Its 32 Ω and 100 Ω ratings (8 W XLR / 4 W SE; 3.8 W XLR / 1.9 W SE) fall either side of it. The Soloist Voyager’s 0.5 Ω headphone output impedance is 1/100 of the load. ^{[9] [3] [4]}
