Good, but Funk package arrived without power cable and RCA cables. I sent a message to Burson customer service, but did not receive any reply.

The System

Listening with

SEAS Pendragon

Focal Utopia · Headphones: open-back, dynamic (40 mm beryllium M-dome), circumaural · discontinued

Impedance: 80 Ω
Sensitivity: 104 dB SPL / 1 mW @ 1 kHz ≈ 115.0 dB/V (calc.)
Frequency response: 5 Hz – 50 kHz
Plugs / cables supplied: 6.35 mm cable and 3.5 mm cable, 4-pin XLR cable; Lemo connectors at the cups
Other: THD <0.2% @ 1 kHz / 100 dB SPL

Matching notes: At 80 Ω and 104 dB/mW, the Focal Utopia is a low-impedance load, and an efficient one: about 0.56 V (4 mW, 7.1 mA) for 110 dB SPL (calc.). Burson does not publish a 80 Ω rating for the Funk. Its 32 Ω and 100 Ω ratings (2.5 W SE; 0.6 W SE) fall either side of it. The Funk’s under 2 Ω headphone output impedance is less than 1/40 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.
