hi all. i'm looking into purchasing a new HT AV receiver. problem is i've only been exposed to a few brands and don't really know the landscape very well. i'm looking for something fairly high-end, but not the highest. looking to spend anywhere from $1K - $2.5K maximum. the brands i'm familar with and are considering: denon kenwood sovereign onkyo pioneer sony can somebody add to this list and provide a list of pros/cons for me?
