Can I buy a streamer that has a digital audio output other than HDMI? (Because if the audio signal passes through my television it's been reduced to crap.) I can deal with USB, Coax, or Optical - anything other than HDMI. To utilize ROKU (the least expensive device in the chain), or most other streamers, it seems I have to upgrade my television (to get an un-defiled pass-through of the digital audio signal), or DAC (to accept audio via HDMI). WHY?
