You'll be bitsreaming the audio to the receiver in its raw digital form over HDMI. So in a way, the audio quality of the player is mute. I'd focus more on video quality and streaming features.
They all seem pretty similar...my primary area of focus with the three is what will output the best audio and the best picture. In terms of bonus features, again they seem fairly similar. I will be purchasing a top notch sound system, most likely the Onkyo S9100 THX, so need the best in terms of audio decoding.
And about the bonus features, does one have a particular feature that actually IS worth making an important consideration for because it is so unique or effective and worthwhile?
Any advice no matter how detailed or brief is greatly appreciated! Thank you in advance!
