I'm looking to get a DVD-A or SACD player in the future. I'm wondering what the consensus is of this community on what makes a proper 5.1 mix. I'd imagine that i'd like to see a mix where the main vocal or instrument is placed in the center, the accompaning musicians in the main's and the backing vocals, percussion, strings mixed between the surrounds with drums and bass mixed between the LFE and mains. I also believe there should have the original 2 channel mix included too! What are your opinions?
