I am currently using a Harmond Kardon AVR 7200 receiver with my HT set-up. I would like to start building toward seperates over the next year or so. The HK receiver is rated at 7 x 100 watts per channel and has a pretty good array of surround sound modes and speakers settings. I currently have about $1,000 in my budget that I can spend to move forward with my plan. I would like to use(3) 2200 model amps to power my front and center channel speakers with the AVR receiver powering the side and back surrounds. I have a few questions concerning using the AVR 7200 as my pre-amp processor.

1. First of all does anyone see anything negative with this approach working toward adding seperates?
2. The receiver has pre outs but I do not see that it has a 12V trigger for the amps. Is this a problem?
3. Any problems using the receiver's amps to power the surrounds with the 2200's for the fronts?

Any recommendations would be helpful
