Sound Quality of Direct TV audio

I recently put a 1/3 octave spectrum analyzer on my Direct TV audio outputs and was shocked to find that they are brick wall filtering all low frequencies below about 150 Hz. Not a gentle roll off mind you, everything from 150 Hz down is gone.

I thought they were supposed to be delivery "high quality" audio. Anyone else discover this or am I getting something unusual?

I have an HD Directv receiver and run HDMI to an EVS moded Oppo 105, which i have do the processing. From there xlrs to Ayre equipment.

I cant measure anything but it sounds really good. Not as good though as the wav files i have on a solid state hard drive I have connected, via usb, to the Oppo.
