The X4000 has more than enough power for that speaker setup and takes the nod on subwoofer EQ using Audyssey MultEQ XT32 which can EQ the subwoofer and also has Audyssey Sub EQ HT (dual sub level/delay calibration) and comes with a 3 year warranty vice only 2 years on the Pioneer. If you plan on connecting a Zone 2, the X4000 can also route an independent HDMI PCM 2.0 signal to Zone 2 and optical/digital coax PCM 2.0 to Zone 3 as well.
