I've never seen a receiver with preamp outputs on the front. doesn't mean one doesn't exists but I've never seen one.
What can't you just run the preamp outputs from the back? connect a dual rca extension cable from the back and run it under the receiver to the front as most receivers have a 1/2" to 1" of clearance underneath.
ok thanks -- may need to just get in my receiver and add my own. another thing if anyone sees this, off topic though -- has anyone seen a receiver with HDMI inputs and will supply whatever HDMI video you're watching at either a composite or S-video output?
most of the receivers I've searched will only output an analog video input.
