Pioneer VSX-LX503 review
The Pioneer VSX-LX503 Network AV Receiver has a 9.2-channel configuration with 180 watts per channel (8 ohms). The VSX-LX503 delivers the summarizing effect of Dolby Atmos / DTS:X technology, perfectly calibrated using the Multi-Channel Acoustic Calibration System (MCACC),, and even expandable to surround sound with channel configuration 7.2.4 using an external amplifier. FlareConnect wireless streaming technology provides multi-room wireless audio playback with simple remote control using the Pioneer Remote App, as well as the ability to enjoy Internet radio and network streaming services using Chromecast built-in wireless streaming and DTS Play-Fi through your smartphone. Powered Zone 3 provides support for a variety of home theater environments. 
Pioneer VSX-LX504 review
Pioneer VSX-LX504 has a configuration of 9.2, power 9 x 180 W (8 Ohms). VSX-LX504 supports the transition to HDR10, HLG (Hybrid Log-Gamma) and Dolby Vision. The MCACC adjusts the sound according to the room and speakers, and also produces a cleaner sound by suppressing the standing waves that arise between walls or the ceiling and the floor. By connecting the VSX-LX504 to Sonos Connect, you can play any music or audio in your Sonos app.
