Burson Funk, Schiit Modi 3, Sennheiser HD 800 S

This is my first Burson piece of equipment so experience is limited, but I hope it will be a positive one.

The System

Listening with

Schiit Modi 3

Sennheiser HD 800 S · Headphones: open-back, dynamic, circumaural

Impedance: 300 Ω
Sensitivity: 102 dB SPL @ 1 V ≈ 96.8 dB/mW (calc.)
Frequency response: 4 Hz – 51 kHz
Plugs / cables supplied: 6.35 mm unbalanced; 4.4 mm balanced

Matching notes: At 300 Ω and 102 dB/V, the HD 800 S is a high-impedance load that needs voltage more than current: about 2.5 V (21 mW, 8.4 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 9 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]}

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.
