Lingjie’s Burson Funk with DALI Oberon 1 and Sennheiser HD 6XX

Published on

Post Info

It handles all of my gears very well and the build quality and aesthetics are excellent.

The System

Listening with

DALI Oberon 1 · Speakers: passive 2-way bookshelf, bass reflex (29 mm soft dome, 5.25 in wood-fibre woofer) · discontinued
  • Impedance: 6 Ω
  • Sensitivity: 86 dB (2.83 V / 1 m)
  • Frequency response: 51 Hz – 26 kHz (±3 dB)
  • Recommended amplifier power: 25 – 100 W
  • Other: max SPL 106 dB; crossover 2.8 kHz

Matching notes: The Oberon 1 is rated at 86 dB (2.83 V / 1 m) into 6 Ω nominal. Burson rates the Funk at 35 W into 8 Ω and 45 W into 4 Ω. At that rating the speaker would reach about 101 dB SPL at 1 m (calc., one speaker, before room gain). DALI recommends 25 – 100 W amplifiers. [1] [2] [3] [4]

Sennheiser HD 6XX · Headphones: open-back, dynamic, circumaural
  • Impedance: 300 Ω
  • Sensitivity: 103 dB SPL @ 1 kHz, 1 V (as published) ≈ 97.8 dB/mW (calc.)
  • Frequency response: 10 Hz – 41 kHz
  • Plugs / cables supplied: 3.5 mm stereo jack plug (6.35 mm adapter); 1.8 m cable
  • Other: THD <0.1% (1 kHz, 1 V)

Matching notes: At 300 Ω and 103 dB/V, the HD 6XX is a high-impedance load that needs voltage more than current: about 2.2 V (17 mW, 7.5 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 10 dB more than that. The Funk’s under 2 Ω headphone output impedance is less than 1/150 of the load.
