Since I will be using HDMI for audio and video, I have been thinking that I would go for the BD60, since the only thing the 80 seemed to offer over it was 7.1 analog audio, which I will not use.
However in looking at the User Manual, there is one feature the BD80 has, that the 60 doesn't, which seems like it might be useful: 'High Clarity Sound'. This is an option to turn off the power to the analog video circuits (i.e., the Component video output) if one is using HDMI, and this is said to produce less interference for the audio channels, and produce a higher quality audio.
I would be very interested if those of you with the BD80--and use HDMI connections--would try out this feature; i.e., listen to the audio with the 'High Clarity Sound' option 'on' and with it 'off', to see if you can perceive any difference. Would greatly appreciate it. If there's no diff, I will stay focused on the BD 60, but if there is a significant improvement I might consider the 80. TIA!
