Awesome experience with my LCD-5. Resolution and clarity even at higher volumes is amazing!

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]}

Matching notes: Burson lists the Soloist 3X GT’s analogue inputs as line level (35 kΩ input impedance). The Holo Audio May is rated at 2.9 V (RCA) / 5.8 V (XLR) output. ^{[4] [5] [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.
