I've never owned a sony amp in the past but I'm looking at the Sony2es AV reciever mostly due to the fact I could hook up my DVD-A and SACD player without a switch box. (using the 2 multichannel inputs). I've owned ONKYO and Denon in the past. I currently have for sale my Onkyo 575x for an upgrade like this. I do 50/50 music/ht. Will it dissapoint me ?
