I Personally own a PS 600. I got to say it one of best I have ever tired. All of my front end of the system is hook up to it and there is ever a day I could live without it. The highs and mids are lifted and the bass got tighter. As for Video the color became more lifelike and the blacks became blacker. I am thinking about getting the PS 1200 for my amp but right now need to save some money.
Wish you the best of luck
