Pre-Amp or Integrated with a processor loop


I am trying to find a pre-amp or an int. amp that has a processor loop so I can run a HT receiver through it when I watch movies...but, can just use the pre-amp or int amp for music. Looking for something used <1000.00.

There have been several threads recently on just this topic. Do a search and you will see that I always recommend the Sonic Frontiers Line-1 for this.
