in reviews of this unit, I have noticed several things that have been brought up as faults in this receiver: no component video switching, lack of 96-192 khz 24 bit DAC and no DTS-ES. My question is what are the real world connotations of this? Is it really anything that problematic? How does it affect music playback (what I would use my system for the most)? How do these problems affect its usefulness for playing movies?
