Adrien, is your brother's Sony a RMA-3100? Big 4"-5" square thing that requires 2 hands, has low ligth & contrast and collects finger grease from the enire family on the touch screen so you know where to find it if you want to do some french fries? Yeah, I had on of those and got the MX-700 instead. I considered the Harmony as well (nice unit), but I liked the way the 700 felt and it's combo of hard buttons and LCD screen. I absolutely love the thing.

MX-700 or Harmony? SVS or HSU? Denon or Yammy or Onkyo or HK? Nice set of problems all with the same answer!
