I listened to the Deftec 7000 series with a Denon Receiver.Everything was powered like your setup. It nearly rattled fillings loose in my mouth! The Deftecs do just fine with a nice receiver for HT. You can get a nice Yamaha,Denon or Marantz sometimes on closeouts in the $1000.00 range..and put the rest of the money in your pocket. I think you will be happy for sometime to come!
Good Luck!
