So it would but be "flat" at ~13hz? My amp isn't an Aegir or Vidar. They have 44k balanced input impedance. My amp is 22k. Just want to make sure I'm not messing up. The load is too low for my D. Sachs DS2 tube linestage.
Thanks for the help,

for Freya+ / Freya N with 2.2uF output coupling caps per phase into 22k SE / 44k balanced input of Vidar:
-3dB at 3.6Hz, and -0.32dB at 13Hz. (in line with Schiit's published specs for 20-20kHz and -3dB points)
for perspective, the volume steps (single click using the front panel knob) on Freya + / Freya N / Freya S are 0.625dB... twice that of the fall-off at 13Hz.
re 13Hz (IMO many more significant non-linearities in the system WRT steady-state frequency response "flatness"):
were the recordings made with a signal chain flat to below 13Hz???
can you even hear or sense (jawbone conduction, etc) that? and the speaker's anechoic response at 13Hz vs at normal bass frequencies at reasonable output levels??? and the in-room response??? there's only so much a DSP correction system can do...
there's more to subjective performance of audio reproduction than steady-state measurements...
look up the frequency response ranges of musical instruments in the bass range (e.g. string double bass, tympani, tuba, etc)
