My Burson Funk easily powers my Omega Speakers. Room is filled with Excellent Sound Quality.

The System

Listening with

Sennheiser HD 600 · Headphones: open-back, dynamic, circumaural

Impedance: 300 Ω
Sensitivity: 97 dB SPL @ 1 kHz, 1 V (as published) ≈ 91.8 dB/mW (calc.)
Frequency response: 12 Hz – 40.5 kHz
Plugs / cables supplied: 3.5 mm stereo jack plug with 6.3 mm adapter; 3 m cable
Other: THD <0.1% (1 kHz, 1 V)

Matching notes: At 300 Ω and 97 dB/V, the HD 600 is a high-impedance load that needs voltage more than current: about 4.5 V (67 mW, 15 mA) for 110 dB SPL (calc.). Burson rates the Funk at 0.15 W (SE) into 300 Ω, which is about 6.7 V RMS (calc.), roughly 4 dB more than that. The Funk’s under 2 Ω headphone output impedance is less than 1/150 of the load. ^{[1] [2] [3] [4] [5]}

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.
