Pioneer has recently introduced VX LX 503 and not yet updated the SC LX 701 series. SC LX 701 is quite old ( 2 - 3 Yrs) model where as Denon AVR x4400h is 2018 model equipped with latest technologies like Heos, Aura and have advanced calibration system. Pioneer runs lot cooler than Denon. Can store multiple speakers calibration settings.No individual cutoff frequency for each channel ( not sure) .Wait for SC LX 703 arrival else look for Pioneer VX LX 503, Yamaha A-1070/2070 and Marantz SR 6012/7012 and are the closest competitors for Denon AVR x4400h.
