Personally, I would go with Denon, Marantz or Outlaw. The sony is difficult to use (I hate the remote), the yamaha is junk compared to the others, Onkyo makes better units, the pioneer is very nice but may not be able to handle the power requirements.
NHT are not easy to drive (but sound great). Most theater receivers are not rated below 8ohm speakers (especially yamaha). Check to see if they can drive the NHT. Also, due to the NHT's lack of efficiency, you will be working these amps hard and may blow the reciever.
Good luck,
Emery
