Emotiva makes the best amps for the money. I own 2 upa 7s and an xpa 5. I started with onkyo 3008 and first added upa 7. Huge upgrade. I now run the 3008 with an xpa 5 and upa 7. I run 9.2 with klipsch reference speakers and the emotiva amps make the system. It is clean and quiet. I have multiple theaters in my house and will eventually use emotiva in every one of them. The upa 7 is no longer made but there are plenty of other models to choose from and every one will blow your mind. Amps like this usually cost triple what they charge and are not make anywhere near as well as these. They way a metric ton though. Enjoy.
