I bet my Yamaha MX-A5000 amp is similar to the amps inside the RX-A3080.
I am using the MX-A5000 amp to power RBH SX-T1/R x 5 and RBH VM-815 x 4 in a 5.1.4 (Atmos, DTSX, DSU, DTSX) system in a 22 ft x 26 ft x 14 ft room and listening distance of 18 ft.
Volume is definitely very loud during action scenes.
