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 use the Toslink digital output, using Wireworld Supernova 7 Glass Toslink cable, from my Wave Broadband TiVo cable box to my Musical Fidelity M1 DAC that connects, using balanced interconnects (XLR), to my Ayre AX-7e integrated amplifier. The music sounds very good.

I'd say its almost always a good idea to use digital outputs form most all commercial AV devices whenever possible in that these devices are for mass markets and most audiophiles would prefer results from their own carefully selected DACs, digital amps, etc.

I am such a dummy!

I forgot my Outlaw Audio receiver has a usb input but I ran a cable from my Genie unit to the receiver and no sound!

I checked all the obvious things...

Curious how it would measure using high definition direct tv receiver and the HDTV service upgrade?

I had a similar problem with my Sony Blu-Ray player. Please review the Menu>Settings & Settings>Audio>"options" for your Genie unit. Look for something that says PCM output. If this does not work, please call Genie and ask them.
