With THX Select2-Certified sound, the tunes will sound like they being heard at an arena, just as movies will have theatre-quality sound. To make the Pioneer Elite VSX-84TXSi easy for the average user, this receiver comes with auto setup as well as Multi-Channel Acoustic Calibration (MCACC). This feature adjusts the sound and EQ to the specific acoustic situation in the room. This is to ensure that the best sound as possible is delivered, suited specifically for the situation. The reviews of the Pioneer Elite VSX-84TXSi have been fairly positive, but this receiver has now been discontinued.
