Asking your question on this forum is sort of like asking a fashion designer forum who makes the strongest shoe strings.
I think you need to look (listen) hard at your local brick and mortar electronics store and you may be pleasantly surprised by something with a household brand name. You might also be surprised how well your existing Onkyo performs against audiophile brand name components.
All that is not to say that I don't really appreciate the cool factor of some of the components already suggested in this thread. I just think that when you want excellent amplification for low investment, the efficiently mass produced receivers are the way to go.
Or, you could buy a Nad or Arcam:).
