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. Pioneer VSX-LX504
