Sounded good right from switch on.

The System

Listening with

Audeze LCD-5 · Headphones: open-back, planar magnetic, circumaural

Impedance: 14 Ω
Sensitivity: 90 dB/1mW (at Drum Reference Point) ≈ 108.5 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 >500 mW (min >100 mW; max 5 W RMS);

Matching notes: At 14 Ω and 90 dB/mW, the LCD-5 is a low-impedance load, and a fairly demanding one: about 1.2 V (100 mW, 85 mA) for 110 dB SPL (calc.). Burson does not publish a 14 Ω rating for the Soloist 3X GT; its nearest published rating is 10 W XLR / 5 W SE into 16 Ω. The Soloist 3X GT’s 0.5 Ω headphone output impedance is 1/28 of the load. ^{[1] [2] [3]}

ADAM Audio T5V · Speakers: active nearfield studio monitor, two-way (5″ woofer + U-ART ribbon tweeter), rear bass reflex

Frequency response: 45 Hz – 25 kHz (-6 dB)
Connectors: XLR / RCA inputs (10 kOhm / 20 kOhm)
Other: max SPL per pair >=106 dB @ 1 m; crossover 3 kHz; THD >80 Hz 0.5%; 5.7 kg

Also in the system

Holo Audio Spring 3 · DAC: discrete R2R ladder DAC with native DSD (optional preamp module, Level 1/2/KTE editions)

Output impedance: 27 Ω (RCA); 54 Ω (XLR)
Output voltage: RCA 2.9 V (PCM) / 1.45 V (DSD128) · XLR 5.8 V (PCM) / 2.9 V (DSD128)
Inputs: USB (isolated; PCM to 1.536 MHz, DSD1024 native); I2S; coaxial; optical; AES
Outputs: RCA; XLR (preamp module optional: 5.8 / 11.6 V)
DAC / chipset: discrete R2R (no DAC chip)
Other: PCM 48 kHz NOS: THD+N 0.00032%, DNR 127 dB; 40 W

Matching notes: Burson lists the Soloist 3X GT’s analogue inputs as line level (35 kΩ input impedance). The Spring 3 is rated at 2.9 V (PCM) / 1.45 V (DSD128) (RCA) / 5.8 V (PCM) / 2.9 V (DSD128) (XLR) output. ^{[6] [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.
